Psychosocial adjustment to unsuccessful IVF and GIFT treatment.

Twenty-one couples for whom in vitro fertilisation (IVF) or GIFT treatment failed were followed-up 15-30 months after treatment and compared with 20 couples for whom IVF had been successful. Current mental health status, quality of life and marital adjustment were assessed via standardised questionnaires. In addition, couples' experiences of IVF/GIFT treatment were explored via a semi-structured interview. Questionnaire results showed that unsuccessful IVF/GIFT recipients cannot be distinguished from general population norms. However, these couples reported more emotional distress relative to those whom treatment had worked and females in particular indicated a lower quality of life. Couples who had at least one child prior to IVF/GIFT treatment tended to show greater emotional distress at follow-up. Both groups gave similar accounts of the positive and negative aspects of IVF/GIFT treatment, but the unsuccessful group felt less supported by the IVF Unit staff and were less satisfied with the counseling they received. The data indicate that post-treatment counseling may be particularly important for facilitating positive reconstructions of the IVF experience when treatment is unsuccessful.

Regional anesthesia for laparoscopy.

A variety of laparoscopic procedures can be performed on patients under regional anesthesia. Diagnostic laparoscopy in elective and emergency patients, pain mapping, laparoscopy for infertility, and tubal sterilization are some examples. The key benefits of regional anesthesia include less emesis, less postoperative pain, shorter postoperative stay, improved patient satisfaction, and overall safety. Regional techniques, such as rectus sheath blocks, inguinal blocks, and caudal blocks, are useful adjuncts to general anesthesia and facilitate postoperative analgesia. Other techniques, such as spinal and epidural anesthesia, and combination of the two, are suitable as a sole anesthetic technique for laparoscopy. The physiologic changes during laparoscopy in the awake patient appear to be tolerated well under regional anesthesia. It is reasonable to assume that with advances in instrumentation and surgical techniques, the role of laparoscopy will increase in the future. The benefits conferred by regional anesthesia make it an attractive option to general anesthesia for many patients and procedures. Successful implementation of regional anesthesia is an important determinant of how anesthesiologists, surgeons, and surgical facilities cope with new challenges. In the future, it could be possible to provide "walk-in/walk-out" regional anesthesia with a real possibility of fast tracking patients through the recovery process after ambulatory surgery. For maximal patient safety, however, facilities offering regional anesthesia must have appropriately trained anesthesia personnel and the equipment necessary for monitoring and providing full resuscitation in the event of complications or a need to convert to general anesthesia.

Patient selection for assisted reproduction.

Patient selection is a critical factor in influencing results in assisted reproduction. Patients should be assessed individually in terms of all relevant fertility factors including age, duration and aetiology of infertility and psycho-social attitudes so that an approximate prognosis of their management can be made. Restrictive criteria for patient selection will enhance a programme's results but at the expense of depriving some couples of their only chance of conception. The best overall management of each individual infertile couple should always remain the main criteria for selection into a particular assisted reproduction programme.

Induction of ovulation for assisted reproduction programmes.

The decision to use enhancement of the natural ovarian/menstrual cycle to attempt collection of several oocytes during IVF and GIFT cycles has dramatically increased the pregnancy rates. Furthermore, the recovery of multiple fertilizable oocytes allows for cryopreservation of extra or surplus pre-embryos (or embryos), with the consequent reduction in the risk of multiple pregnancies and the improvement of the cumulative pregnancy rate following IVF and GIFT cycles. Here, we have reviewed the underlying physiological mechanisms in the natural ovarian-menstrual cycle. Subsequently, we have analysed the more frequently utilized ovarian stimulatory regimens with special emphasis on the use of gonadotrophins. Several conclusions may be drawn from the experience to date with these methods of ovarian stimulation. Primarily, lower doses of medication, when used appropriately, may result in a more favourable outcome. Most significant, it seems to be beneficial to tailor the dosages and timing of drug administration to the patient's individual response to medication. Because ovarian stimulation therapy is difficult to manage, a major challenge in reproductive endocrinology has been to develop stimulation protocols that would 'ideally' synchronize the development of a cohort of follicles. The development of GnRH analogues (agonists and antagonists) and the experience (both in women and macaques) gained so far when these drugs are used in combination with gonadotrophins, have helped both in the understanding of the underlying physiology and in the improvement of clinical results.

Assisted conception. Health services and evaluation.

Comparison of assisted conception in Australia, the United Kingdom, and the United States indicates that further rapid growth in services is likely in many countries. Better data on pregnancy rates and the outcome of pregnancy, as well as standardized reporting of national results, are needed to monitor the effectiveness of treatment.

Obesity increases the risk of spontaneous abortion during infertility treatment.

OBJECTIVE: This study examines the relationship between body mass and the risk of spontaneous abortion in a large cohort of patients who received infertility treatment. RESEARCH METHODS AND PROCEDURES: This is a retrospective study using data on pregnancies (n = 2349) achieved after treatment in a tertiary medical center from 1987 to 1999. One pregnancy per subject was included, and the subjects were stratified into five body mass groups based on body mass index (BMI): underweight, <18.5 kg/m(2); normal, 18.5 to 24.9 kg/m(2); overweight, 25 to 29.9 kg/m(2); obese, 30 to 34.9 kg/m(2); and very obese, > or =35 kg/m(2). Logistical regression analysis was used. RESULTS: The overall incidence of spontaneous abortion was 20% (476 of 2349). The effect of BMI on the risk of spontaneous abortion was significant after adjusting for several independent risk factors. Compared with the reference group (BMI 18.5 to 24.9 kg/m(2)), underweight women had a similar risk of spontaneous abortion, whereas there was progressive increase of risk in overweight, obese, and very obese groups (p < 0.05, p < 0.01, and p < 0.001, respectively). DISCUSSION: Of all known risk factors for spontaneous abortion, the control of obesity has great significance because it is noninvasive, potentially modifiable, possibly amenable to low cost, and self-manageable by patients. This study established a positive relationship between BMI and the risk of spontaneous abortion in women who became pregnant after assisted reproductive technology treatment.

[Hormonal and ultrasound monitoring of early pregnancy--differential diagnosis of extrauterine pregnancy and multiple pregnancy].

In this study sonographical and hormonal findings in 63 patients with intrauterine singleton pregnancy were compared with 18 patients with multiple pregnancies and 28 patients with ectopic pregnancy. The earliest detection of the intrauterine gestational sac was obtained with a HCG level of 659 mlU/ml. The sonographical development correlated well with HCG values. There was no statistically significant correlation between gestational age and HCG. In multiple pregnancies with sonographical findings comparable to the development in singletons HCG values were remarkably elevated. A discrimination between multiple and ectopic pregnancies by sonographical and hormonal criteria cannot be performed sufficiently in a HCG zone of 1500 mlU/ml. Close sonographical and hormonal follow-up until diagnosis of the intrauterine pregnancy is necessary.

[Continuous pulsatile subcutaneous gonadotropin stimulation in polycystic ovary syndrome: a therapeutic alternative].

In order to improve the ovarian response to exogenous gonadotropins and to reduce the risk of the ovarian hyperstimulation syndrome and of multiple pregnancies, human menopausal gonadotropin (hMG) was administered by continuous pulsatile subcutaneous (s.c.) infusion via a portable pump. The effectiveness of pulsatile hMG treatment was first demonstrated in a control group comprising 7 females with regular ovulatory cycles, who underwent gonadotropin ovarian superovulation and subsequent IVF/GIFT procedures for tubal or male factor. All pulsatile s.c. hMG cycles were ovulatory and one clinical pregnancy was achieved. In this group, ovarian response was similar following intramuscular (i.m.) and pulsatile s.c. hMG therapy, with a marked reduction of preovulatory serum levels of oestradiol in the pulsatile s.c. hMG cycles. In a prospective study, 11 patients with overt polycystic ovary syndrome (PCO) who failed to ovulate in response to clomiphene, received i.m. hMG ovarian superovulation treatment in 19 cycles and pulsatile s.c. hMG in 21 cycles. Following i.m. hMG treatment, only 10 cycles were ovulatory; 7 cycles had to be cancelled for impending ovarian hyperstimulation syndrome. Following pulsatile s.c. hMG treatment, 15 cycles were ovulatory, only 3 treatment cycles had to be disrupted for multifollicular ovarian response. Both modes of treatment were similar in terms of requirement of hMG ampoules, number of preovulatory follicles, preovulatory serum levels of oestradiol and duration of the preovulatory oestradiol rise. The total duration of hMG treatment was significantly increased following pulsatile s.c. hMG. It is concluded, that in overt PCO syndrome, continuous pulsatile s.c. administration of hMG is an effective method to induce follicular maturation and to achieve ovulations.(ABSTRACT TRUNCATED AT 250 WORDS)

[CA-125 serum level in early pregnancy follow hMG/hCG stimulated and unstimulated cycles].

The CA-125-antigen could not only be identified in the epithelium of serous ovarian carcinoma, but also in the regular surface epithelium of the endometrium, the decidua and the peritoneum. The aim of this study was, to examine the pattern of CA-125 in the serum of women at early stages of pregnancy, after hMG/hCG-stimulation and subsequent insemination, IVF or GIFT. In particular, it was differentiated between simple or twin pregnancies, ovarian hyperstimulation syndrome and mole pregnancies. 16 patients, who spontaneously became pregnant after cyclus-monitoring, served as a control group. Among the total of 77 patients, 16 women with single pregnancies without stimulation showed an increase of CA-125 values to maximum amounts of 42.9 +/- 18.8 U/ml in the 8th week. 21 patients with single pregnancies after hMG/hCG-treatment and IVF, exhibited maximums of 97.5 +/- 66.8 U/ml in the 6th week, in cases of twins (n = 10) of 216.8 +/- 85.1 U/ml in the 7th week. Considering the group with the hMG/hCG-stimulation and following insemination (n = 20), maximum values of 91.4 +/- 57.3 U/ml were found in the 6th week, just as in the IVF-group. In cases of ovarian hyperstimulation syndrome (n = 5) as well as in such of a mole pregnancy (n = 5), drastically elevated values of 9519 and 1496 U/ml respectively, have been demonstrated. The decidua is regarded as a presumable source of high antigen levels in normal pregnancy, while the peritoneum is assumed to be such as for the ovarian hyperstimulation syndrome. Concerning mole pregnancy, the antigen levels could possibly emerge from the amniotic fluid.(ABSTRACT TRUNCATED AT 250 WORDS)

[Initial experiences with amniocentesis for prenatal diagnosis in pregnancy following in-vitro fertilization].

We report on first experiences with amniocentesis in 63 pregnancies after IVF treatment over a period of 3 years. It is shown, that there is no increased risk through amniocentesis; it does not require special precautions. Above average number of aberrations could be found in amniotic cultures in cases where it could be identified additionally in one parent. It remains to be seen, whether the small number and sterility causes were coincidental or manifest themselves in future, especially, if the sterility concerned can be classified as idiopathic. The occurrence of trisomy 21 in accordance with the frequency is to be expected in the group of persons over 35 years of age and no increased risk through IVF treatment can be found.

Treatment of endometriosis-associated infertility.

The choice of treatment options for endometriosis-associated infertility has been both controversial and complex, largely because of lack of data. In the last 10 years, better data from numerous studies with improved design support laparoscopic ablation and/or resection of lesions as the most successful for both minimal/mild and moderate/severe/extensive disease. Laparotomy should be performed when necessary. Observation alone is sometimes indicated in young women with minimal/mild disease. Hormonal suppression has no identifiable role, except perhaps for severe/extensive disease, before IVF or GIFT. Ovarian stimulation with clomiphene or gonadotropins and concomitant intrauterine insemination is indicated for minimal/mild disease. IVF and GIFT are often best for those who have failed other treatments, have advanced age, prolonged infertility, and/or multiple-factor infertility.

A modern view of male infertility.

It is archaic to view male factor infertility today separately from in vitro fertilization (IVF) and treatment of the female partner. Oligoasthenozoospermia may be an inherited condition (most likely on the Y chromosome), and is refractory to any treatment of the male including hormones and varicocelectomy. IVF technology is the only justifiable approach for achieving a pregnancy in these couples. The reasons for this view and the suggested modern approach to couples with oligoasthenozoospermia are outlined in this review. However, obstructive azoospermia is different as it can be successfully corrected with microsurgery in over 90% of men. When it cannot be corrected, as in congenital absence of vas, microsurgical sperm retrieval combined with IVF can still be highly effective in producing pregnancy with sperm from the husband. The most important arena for research into male infertility in the next decade will be to map out the deletions on the Y chromosome that might result in defective spermatogenesis, and which probably cause most cases of non-obstructive male factor infertility.
