The effect of consecutive cycles of clomiphene citrate therapy on endometrial thickness and echo pattern.

OBJECTIVE: To determine whether successive cycles of clomiphene citrate affect endometrial thickness. METHODS: Thirty-four women presenting for treatment of anovulation, oligoovulation, or follicle maturation defects were given the smallest dose of clomiphene citrate necessary to attain a mature follicle. If no pregnancy ensued, the same dose was continued if a follicle 18-24 mm in diameter and a serum estradiol (E2) level greater than 200 pg/mL were achieved. Ethinyl E2 was supplemented for poor cervical mucus only. Endometrial thickness and echo patterns were measured each cycle at peak follicular maturation. RESULTS: There was no difference in mean endometrial thickness during the first six cycles of therapy, nor was there a trend for thickness to increase or decrease with successive cycles with or without the addition of ethinyl E2. There was no change in the distribution of echo patterns with successive cycles of clomiphene citrate. Post-treatment measures of thickness and echo pattern did not differ from baseline pre-treatment values. The homogeneous hyperechogenic pattern was the rarest. Mean serum E2 and progesterone levels at mid-cycle did not change with successive cycles. CONCLUSION: One proposed mechanism for the dichotomy between ovulation and pregnancy rates after clomiphene citrate therapy is that the drug adversely affects the endometrium. If clomiphene citrate does affect implantation adversely, the mechanism does not seem to be related to thinning the endometrium or causing an echo pattern that indicates a poor prognosis. The data also suggest that estrogen supplementation does not influence endometrial thickness and would best be used exclusively for hostile cervical mucus.

Using complete breastfeeding and lactational amenorrhoea as birth spacing methods.

The aim of this study was to evaluate the effectiveness of lactational amenorrhoea and to determine the relationship between extended breastfeeding and the return of fertility. Breastfeeding pattern, basal body temperature, cervical mucus, salivary ferning, vaginal blood discharge, frequency of sexual intercourse, and the presence of ovulation in the first cycle after the resumption of menses with ultrasonography were evaluated in 40 women. All subjects completed the study with only one case of incomplete breastfeeding. No pregnancies were observed. The mean number of feeding sessions and mean interval between sessions decreased significantly (p <0.01) during the first six months postpartum (7.5 +/- 1.3 after 60 days postpartum vs. 5.7 +/- 2.1 after 180 days, and 3.6 +/- 0.8 vs. 5.1 +/- 0.9, respectively). Eight women (20%) menstruated before weaning, but none had an adequate thermal shift, while 32 (80%) had their first vaginal bleeding after weaning with 12 (37.5%) registering an adequate thermal shift. Both basal body temperature and salivary ferning proved to be suggestive of ovarian activity, while mucus characteristics were not reliable in identifying fertile periods. Our study showed that breastfeeding associated with lactational amenorrhoea proved to be a good method of postpartum fertility control. Since the importance of supplementation is still debated, it is recommended that a "complete" breastfeeding program be used.

[Parenteral contraceptive drugs: depot progestins].

Depot progestins as injectables, implantables or vaginal rings are suitable for contraception in those female patients, in which risk factors (e.g. cardiovascular risk) exclude the use of estrogen-progestin mixtures. In this paper the mode of action, indications, contraindications, advantages and disadvantages of the various methods using depot-progestins are discussed. Injectables contain either medroxyprogesterone acetate or norethistronenantate; both steroids are released slowly within a limited time interval (2 to 4 months) out of a depot. The major effect is a change of the cervical mucus. Side-effects are disturbances of the menstrual cycle (e.g. breakthrough bleedings) as well as an amenorrhea after frequent use (up to 50% of all cases). The subdermal implantables (Norplant 2 or 5) release levonorgestrel out of a depot over a time period of at least 5 years. Steroid plasma levels are lower than in those patients using a progestin-only pill. Side-effects of implantables are disturbances of the menstrual cycle (e.g. breakthrough bleeding); in patients who desire to conceive a child or suffer from undesirable side-effects the implantables can be removed at every time. The progestin releasing vaginal rings are in a stage of controlled clinical trials. The advantages depend on ethe easy mode of administration (implantation or removal). Side-effects are also breakthrough bleedings.

The cervical factor of infertility and intrauterine insemination.

Results with intrauterine insemination in 25 couples are presented. The indication for this procedure was a cervical factor of infertility. After an extensive fertility survey in both partners, intrauterine insemination was performed four to seven times per cycle with up to 0.8 ml fresh semen per insemination. Only the first ejaculatory spurt was used. Prophylactic antibiotics were given to all female partners during the insemination period. Within a mean of 6 months 13 couples reported pregnancies (52%). Except for one midtrimester abortion that was probably due to obstetrical reasons, the abortion rate was 33.3%. There were no side effects related to the insemination procedure. Our data indicate that, with appropriate safeguards, intrauterine insemination should be regarded as a safe and effective method for the treatment of the cervical factor of infertility.

A new diagnostic aid for natural family planning.

INTRODUCTION: We have studied the use-effectiveness of salivary ferning as a diagnostic testing aid to natural family planning. We used PG/53, a pocket microscope. MATERIALS AND METHODS: Use of natural family planning methods was studied in 32 women who used the new technology PG/53 to detect the fertile period. By this means the women observed their menstrual cycles and other markers of fertility, such as basal body temperature and appearance of cervical mucus. RESULTS: Of the 32 women participating in this research, 28 women had a good salivary test with positive ferning by the microscope in the same period as other markers of fertility. In 4 cycles the ferning was uninterpretable as there was no correspondence with the cycle phase. Ferning began 1-2 days before cervical mucus appearance, and lasted a mean of 6.2 days. Ferning occurred, on average, 7.2 days before the first day of temperature shift. CONCLUSIONS: There is a direct correlation between salivary ferning and fertile period. Salivary ferning may be used as a new parameter to aid women to detect the fertile period in combination with other symptothermal methods of ovulation detection. We now need further research in order to improve the use-effectiveness of salivary ferning.

Chlamydiae in the ejaculate: their influence on the quality and morphology of sperm.

BACKGROUND: Given the lack of information concerning the role of Chlamydia trachomatis in male fertility, the aim of this study was to ascertain and analyze the quality of Chlamydiae-positive and -negative semen. MATERIAL AND METHODS: Sperm count was performed according to the 1999 World Health Organization (WHO) laboratory manual for examination of human semen and sperm-cervical mucus interaction, and sperm survival was assessed by a 120-min test. The evaluation of the morphological examination of ejaculates was carried out using the sasmo (strict morphological analysis of ejaculates) computer program. Chlamydiae were detected by immunofluorescent reaction using the Progen Biotechnik GmbH diagnostic set. Fisher's exact test and the chi-quadrate test were used for statistical analysis. RESULTS: Of the total of 627 sperm samples examined, Chlamydiae were detected in 136 cases (21.7%). Sperm analysis showed significant differences between Chlamydiae-positive and -negative samples. The Chlamydiae-contaminated group showed normal sperm morphology 14.4% lower, volume 6.4% lower, concentration 8.3% lower, motility 7.8% and velocity 9.3% lower than in Chlamydiae-negative samples. The average values for normal spermatozoa and motility in the Chlamydiae-positive group were also significantly reduced. CONCLUSION: Chlamydia trachomatis was found to be a possible factor in sperm pathology. These results could help to elucidate the role of Chlamydia trachomatis in male infertility.

[Zinc content analysis in serum, seminal plasma and spermatozoa of asthenozoospermic and oligoasthenozoospermic patients].

OBJECTIVE: To detect the zinc content in serum, seminal plasma and spermatozoa of asthenozoospermic and oligoasthenozoospermic patients, and analyse the relationship between zinc changes and sperm density as well as sperm motility. METHODS: Sperm quality analysis was made according to the WHO standard of Laboratory Manual for the Examination of Human Semen and Sperm-cervical Mucus Interaction (4th edition), and then 90 asthenozoospermic patients, 60 oligoasthenozoospermic patients and 20 fertile men with normal sperm quality were screened out as the objects to be researched. The zinc content in their blood, seminal plasma and spermatozoa was detected by flame atomic absorption spectroscopy. And then a statistical analysis was made on the test results. RESULTS: The blood zinc content among the 3 groups had no significant difference; the seminal plasma zinc of asthenozoospermic and oligoasthenozoospermic patients were significantly lower than that of fertile men (P < 0.05); the spermatozoa zinc content of oligoasthenozoospermic patients was significantly higher than that of asthenozoospermic patients and fertile men (P < 0.01), respectively. CONCLUSION: There may be a positive relationship between the feebleness of sperm production and motility of asthenozoospermic and oligoasthenozoospermic patients and the lower content of seminal plasma zinc; however, the relationship between the higher spermatozoa zinc content and the function of sperm production and sperm motility is still not clear, on which a further study should be made.

Antibodies to spermatozoa. VII humoral and cellular aspects of sperm inmunity and infertility.

The occurrence of sperm antibody in serum and cervical mucus of women from intertile couples in the serum of their male partners, as well as cellular immunity to sperm, has been studied by agglutination and immobilization techniques. For a total of about 260 couples, the tests on serum showed that 18% of the women and 8% of the men were positive by the Kibrick technique and that 15% of the women and 4% of the men were positive by the F-D technique. The women who were positive in their cervical mucus were 8% of the group by the K-agg (Kibrick agglutination) technique, 2% by the MIS-agg. (Microscale agglutination) technique, and 40% by the MIS-imm. (Microscale immobilization) tecnique. In considering all three techniques. 42% of a group of 132 women were positive. Cellular immunity to sperm, by the Migration Inhibition method, was positive in 18% and zero per cent of infertile and fertile women, respectively.

Influence of smear quality on the rate of detecting significant cervical cytologic abnormalities.

OBJECTIVE: To determine the correlation between cervical smear quality and the rate of detecting significant epithelial abnormalities. STUDY DESIGN: Smear quality was assessed routinely in a series of 68,328 cervical spatula and spatula/brush combination smears received by our laboratory during 1993. Quality was assessed using a semiquantitative method, evaluating the presence of endocervical cells, metaplastic squamous cells, endocervical mucus and overall squamous cellularity. RESULTS: Smear quality was graded as unsatisfactory, poor (18,680 smears), fair (9,739 smears) or good (39,909 smears); unsatisfactory smears were eliminated from the analysis. There was a highly significant correlation between smear quality and the rate of detecting significant epithelial abnormalities (chi 2=127.52, df=2, P<.001). CONCLUSION: Smear quality is an important issue. Many significant abnormalities are potentially missed because of poor smear quality.

Timing of onset of contraceptive effectiveness in Norplant implant users. Part I. Changes in cervical mucus.

OBJECTIVE: To provide scientific data regarding the changes in cervical mucus within the first hours to days after Norplant implant insertion and to estimate when the cervical mucus is hostile enough to suggest a contraceptive effect. DESIGN: Multicenter, clinical descriptive study. SETTING: Family planning clinics. PATIENT(S): Forty-two women who were between days 8 and 13 of their menstrual cycle and who had requested Norplant implants were admitted to the study. INTERVENTION(S): Cervical mucus and blood samples were obtained. MAIN OUTCOME MEASURE(S): Cervical mucus scores, sperm penetration distances, and serum levels of progesterone, estradiol, and levonorgestrel. RESULT(S): The median cervical mucus score observed at baseline was 6 ("fair"), indicating that the mucus was already somewhat hostile before insertion of the Norplant implants. The median scores declined to 5 at 12 and 24 hours and continued to decrease through day 7 to 2 ("poor"), a score that is judged as hostile to sperm penetration. Overall, 73% of all subjects had a poor cervical mucus score by 3 days after insertion; at 7 days after insertion, 90% exhibited poor mucus and none had a good score. There was a substantial drop in the overall median distance traveled by the vanguard sperm after 12 hours for each cervical mucus score grouping. The distance traveled decreased rapidly between 12 and 24 hours to < 0.5 cm in subjects with fair and poor mucus, and by day 3, 91% of the subjects exhibited poor sperm penetration. CONCLUSION(S): On the basis of our findings, deterioration of the quality of the cervical mucus and sperm penetration is evident by 24 hours after insertion, although not to a level that would suggest adequate protection until 72 hours after insertion. Therefore, we are confident in recommending that backup methods of contraception (e.g, condoms) need not be used for more than 3 days after insertion, even when the implants are inserted close to ovulation. These findings provide policy makers, clinic managers, and clinicians with important information about how they can improve client access to Norplant implants.

Fertility awareness and natural family planning.

Information about fertility awareness helps to fulfil the broader definition of the services many family planning clinics offer. Although information about natural family planning is requested by a small number of clients seeking family planning advice, many more clients benefit from information about fertility awareness. Fertility awareness is far more than just basic reproductive anatomy and physiology; fertility awareness involves understanding basic information about fertility and reproduction, being able to apply it to oneself, and being able to discuss it with a partner or with a health professional. Fertility awareness is fundamental to understanding and making informed decisions about reproductive health and sexual health. If clients have a better understanding of fertility awareness, they are in a stronger position to make informed decisions about how they wish to manage their reproductive and sexual health, for example: (1) Fertility awareness information is used to help couples to plan pregnancies as well as to avoid them. This can be helpful to couples who are having difficulty conceiving, for the timing of intercourse or for the timing of some of the sub-fertility investigations. (2) The information is also useful when helping couples to understand how each method of family planning works--how the family planning method interrupts normal fertility, how the method will fail if not used correctly, and how fertility returns when the method is discontinued. (3) Women who are fully breastfeeding value the knowledge about reduced fertility, as do women during the perimenopausal years who value being given clear information about their declining fertility. (4) When counselling couples about the importance of avoiding sexually transmitted diseases it is important they understand sexually transmitted diseases may damage their fertility. (5) Couples who choose only to use a barrier method during the time they think the woman is fertile are a group who do not readily identify themselves to family planning providers. These couples often do not have adequate information about fertility awareness. Advances in technology and the understanding of ovulation, ovum and sperm survival have confirmed that the guidelines used to teach fertility awareness and natural family planning effectively identify the fertile phase of the menstrual cycle. Serial ultrasound studies on the ovaries during the menstrual cycle have confirmed the accuracy of the hormonal assays in pinpointing the likely time of ovulation. Ultrasound studies have also shown that subjective observations of the alterations in cervical mucus and the basal body temperature rise are accurate indicators of the fertile phase. Research on the chances of conception on each day of the menstrual cycle, using hormonal assays to estimate the time of ovulation, was carried out in 1994 by Weinberg and Wilcox. Their results showed that the timing of sexual intercourse, in relation to ovulation, strongly influences the chance of conception. Conception only occurred during a 6-day interval that ended on the estimated day of ovulation. The chances of conception fell to zero 24 hours after ovulation. Several different methods of natural family planning are taught; some methods depend on only using one of the indicators of fertility, others are based on two or more indicators. The main indicators of fertility are: observing the cervical mucus, recording the basal body temperature, palpating the cervix and a calculation based on the cycle length. Research studies performed using a combination of the indicators of fertility show that the failure rate using a combination is less than most of the studies which use a single indicator. In each case the method failure is far lower than the user failure. (ABSTRACT TRUNCATED)

Clinical relevance of sperm morphology assessment using strict criteria and relationship with sperm-mucus interaction in vivo and in vitro.

OBJECTIVE: To determine the relationship of the differentiated morphological pattern of semen samples according to strict criteria and sperm-mucus interaction in vivo and in vitro. PATIENTS: One hundred sixty-three randomly chosen couples with long-standing infertility (median duration of infertility 4 years, range 1 to 19 years). SETTING: Outpatient clinic of the fertility unit at the Women's University Hospital of the University of Heidelberg, Heidelberg, Germany. MAIN OUTCOME MEASURES: Sperm morphology assessment using strict criteria (Tygerberg or Norfolk classification) parallel to standard methods of sperm analysis: Evaluation of the cervical factor of patients' female partners, including a microbial screening of genital secretions of both partners; Examination of sperm migration ability in vivo under hormonally controlled conditions for the cervical mucus (CM) quality and in vitro with the crossed sperm-CM penetration test performed with CM of patients' partners, as well as with CM and spermatozoa of donors; Determination of the selection capacity of CM with regard to sperm morphology by means of a biological model; Prospective analysis of the differentiated morphological pattern with respect to couples' subsequent fertility within 6 months. RESULTS: Using stict criteria, amorphous sperm heads were the most frequently found sperm anomaly (severely amorphous forms: median, 28%; range, 4% to 62%). The morphology index offered a median of 45% (range, 7% to 80%). Results correlated significantly with routine sperm analysis, including standard morphology. The morphological pattern differed significantly in samples offering adequate or inadequate ability to penetrate CM in the standardized sperm-CM penetration test or in the postcoital test, with the percent of severely amorphous heads as the most important parameter. Neck and tail defects did not play an important role. During passage of mucus columns in vitro, the rate of pathological spermatozoal forms was reduced significantly, from a median of 65% to a median of 38%. Better functional capacity of spermatozoa with normal head morphology also was reflected by a significantly higher pregnancy rate under natural conditions of conception. CONCLUSIONS: Sperm morphological properties, determined with strict criteria, are important factors for sperm ability to penetrate the mucus barrier at the uterine cervix before reaching the site of fertilization, but sperm morphology is only one among other parameters determining the complex phenomenon of sperm-mucus interaction.

Influence of the quality of the cervical mucus on sperm penetration: comparison of the morphologic features of spermatozoa in 101 postcoital tests with those in the semen of the husband.

The purpose of this study was to determine the frequency of abnormal spermatozoa in mucus by a postcoital test and to compare the findings with the teratospermia in a control analysis of the husband's semen. These data obtained from 101 hypofertile couples were correlated with the quality of mucus, which was classified into three categories according to rigorous scoring procedures. The morphologic features of spermatozoa were evaluated by the same investigator and classified on the basis of a system that allowed for multiple entries. This method provided an exact description when several anomalies were identified on the same spermatozoon. By this approach, spermofiltration of the mucus was determined both qualitatively and quantitatively. The proportion of abnormal spermatozoa decreased in the cervical mucus, compared with semen, when the mucus was abundant and of normal quality (32.3% +/- 8.7% in mucus, versus 55.7% +/- 13.9% in semen). The elimination of tail anomalies depended upon the quality of the cervical secretion. A normal mucus eliminated spermatozoa with abnormal heads only if they were associated with a tail anomaly.

Experiences with a tampon-spermicide device.

A tampon applicator is described in which a spermicidal solution is stored in the plunger and released into a disposable tampon just prior to insertion of the tampon. The experiences of 26 volunteers who used the device at the time of coitus suggest that the method is both acceptable and feasible, although four of the ten subjects attempting tampon removal by themselves experienced some difficulty. Postcoital studies of the cervical mucus near the time of ovulation were conducted on 16 subjects and no motile spermatozoa were found. This suggests a high degree of theoretical effectiveness.
