Gamete intrafallopian transfer. Comparison of epidural vs. general anesthesia.
OBJECTIVE: To investigate the reproductive outcome of laparoscopic gamete intrafallopian transfer (GIFT) performed under epidural vs. general anesthesia. STUDY DESIGN: Retrospective analysis of 110 consecutive laparoscopic GIFT procedures performed under general or epidural anesthesia. All patients underwent controlled ovarian hyperstimulation employing human menopausal gonadotropin and gonadotropin releasing hormone agonist, given either in the midluteal or early follicular phase. Data were retrieved concerning age, diagnosis, estradiol levels and maximum follicular diameter at the time of human chorionic gonadotropin injection, percentage of mature oocytes retrieved and number of oocytes transferred. These variables were compared using the independent means t test. Pregnancy rates and outcome between the general and epidural anesthesia groups were compared with the chi 2 test. RESULTS: Of the 110 procedures, 84 were performed under general anesthesia, whereas 22 were done using epidural anesthesia. Four procedures started with epidural anesthesia and were converted to general anesthesia because of upper abdominal discomfort. The success rate of epidural anesthesia, therefore, was 85% (22/26). There were no significant differences in the confounding variables between the general and epidural anesthesia groups. However, patients receiving epidural anesthesia had a significantly higher pregnancy rate, 59.1%, and a live birth rate of 40.9% as compared to 31.0% and 21.4%, respectively, for the general anesthesia group. CONCLUSION: Laparoscopic GIFT can be performed safely under epidural anesthesia. Because of the higher pregnancy and live birth rates, epidural is the anesthetic of choice for GIFT. However, a prospective, randomized study is needed to confirm the above observation.

Correlation between semen parameters of electroejaculates and achieving pregnancy by intrauterine insemination.
OBJECTIVE: To investigate whether any parameter in the routine semen analysis of electroejaculates is correlated with success in achieving pregnancy by IUI. DESIGN: Retrospective observational study. SETTING: An Assisted Reproductive Program at a tertiary care university center. PATIENT(S): Twenty-seven anejaculatory men with spinal cord injury (n = 24) or history of retroperitoneal lymph node dissection (n = 3), thirteen of whom attempted conception with their wives. INTERVENTION(S): Anejaculatory men underwent rectal probe electroejaculation and electroejaculates were used for IUI. MAIN OUTCOME MEASURE(S): Statistical correlation of semen parameters between electroejaculates that resulted in pregnancy and those that did not. RESULT(S): Seven pregnancies resulted from 56 IUIs using electroejaculates (pregnancy rate = 12.5% per IUI). The total motile sperm count and percentage of normal morphology were significantly higher in the specimens that resulted in pregnancies than those that did not. However, there was no statistically significant difference observed in pH, sperm concentration, or percentage of motility between the two groups. Swim-up techniques used to process electroejaculates significantly improved the motility of the specimens. No pregnancy occurred beyond the fifth IUI attempt. Repeated electroejaculation and duration of spinal cord injury had no effect on the quality of the ejaculates. CONCLUSION(S): The total motile sperm count and the percentage normal morphology of electroejaculates correlate with success in achieving pregnancy by IUI. Because repeated electroejaculation does not improve quality of ejaculate, the initial semen analysis of electroejaculates is not only useful in counseling couples undergoing such treatment program but should be planned for use as an inseminate.

Gamete intrafallopian transfer. Does smoking play a role?
OBJECTIVE: To investigate the effects of active and passive cigarette smoking on the outcome of gamete intrafallopian transfer (GIFT). STUDY DESIGN: A retrospective analysis of 98 patients who had laparoscopic GIFT was performed. Data were retrieved concerning age, diagnosis, amount of human menopausal gonadotropins (hMG) used for controlled ovarian hyperstimulation (COH), and number of oocytes retrieved and transferred. A detailed smoking history, if any, of patients and household members was obtained from chart review and an additional telephone survey. Pregnancy rates and outcome in active and passive smokers were compared to those of non-smokers. RESULTS: No difference was observed among active smokers (n = 19), passive smokers (n = 13) or nonsmokers (n = 66) regarding diagnosis, age percentage of mature oocytes retrieved or number of oocytes transferred during GIFT. However, active, but nor passive, smokers consumed a higher amount of hMG for COH as compared to nonsmokers. More important, pregnancy and live birth rates for active smokers (15.8% and 10.5%, respectively) were significantly lower than those for passive smokers (46.2% and 23.1%) and nonsmokers (45.5% and 33.3%). No difference, however, was noted between the latter two groups. CONCLUSION: Our results show that active, but not passive, smoking has a negative impact on GIFT pregnancy rates and outcomes. It is important to counsel patients against cigarette smoking prior to GIFT, but whether smoking cessation will improve the outcome needs further study.

Electroejaculation and assisted reproductive techniques for anejaculatory infertility.
OBJECTIVE: To report our experience with electroejaculation combined with intrauterine inseminations (IUI) and other assisted reproductive technologies. METHODS: Anejaculatory men desirous of fertility were evaluated in our Assisted Reproductive Program. Between March 1991 and December 1994, 26 men (age 24-48) underwent a total of 84 electroejaculations. Causes of anejaculation included spinal cord injury (n = 23) and retroperitoneal lymph node dissection (n = 3). Female partners were super-ovulated to improve the pregnancy rate. The success in sperm retrieval and pregnancy rates were determined, and the quality of electroejaculates was evaluated. RESULTS: Seventy-seven of 84 (92%) electroejaculations were successful, defined by retrieval of more than 10 x 10(6) total and more than 10(6) motile spermatozoa. Mean sperm count was 65 million/mL (range 0-569), but mean motility was only 16% (range 0-66). Mean normal morphology was 27% (range 0-71). Ten couples attempted conception. Fifty cycles of IUIs were performed, resulting in four normal term infants and one spontaneous abortion (pregnancy rate 10% per IUI). One patient failed to conceive with eight cycles of IUIs but became pregnant with in vitro fertilization-embryo transfer with micromanipulation using electroejaculates; she delivered a set of healthy twins. Two couples elected donor sperm insemination after failing to conceive by IUI with electroejaculates; both became pregnant. CONCLUSION: Electroejaculation offers an encouraging pregnancy opportunity for anejaculatory men who otherwise are considered infertile. Marked asthenospermia is observed in electroejaculates, the etiology of which remains obscure. Further studies to elucidate the cause may improve pregnancy rates.

A prospective series of unruptured ectopic pregnancies treated by tubal injection with hyperosmolar glucose.
OBJECTIVE: To evaluate the safety and efficacy of hyperosmolar glucose injection in select unruptured tubal gestations with hCG levels less than 2500 mIU/mL. METHODS: In this prospective series, 16 patients with an hCG titer less than 2500 mIU/mL and an unruptured ectopic pregnancy were treated by tubal injection with hyperosmolar (50%) glucose. Hyperosmolar glucose was injected transabdominally into the antimesenteric site of the tubal pregnancy, using a 20-gauge spinal needle. The main outcome measures evaluated were duration of surgery, success rate, time to resolution, and follow-up tubal patency rates. RESULTS: Ninety-four percent (15) of the subjects were treated successfully with a median time to resolution of 24 days (range 5-78). The one treatment failure required methotrexate because of rising hCG titers and worsening pain 4 days after the patient was treated with hyperosmolar glucose. The mean (+/- standard error) duration of surgery was 45 +/- 6 minutes. So far, all ten patients undergoing postoperative hysterosalpingograms have demonstrated tubal patency in the treated tube. CONCLUSION: Laparoscopic injection with hyperosmolar glucose is an effective, systemically nontoxic alternative treatment for select unruptured ectopic pregnancies (hCG less than 2500 mIU/mL) that achieves tubal patency rates comparable to other conservative medical and surgical treatments.

Atrial natriuretic peptide, oestradiol and progesterone in women undergoing spontaneous and gonadotrophin-stimulated ovulatory cycles.
The objective of this study was to examine the relationship between the concentrations of oestradiol and progesterone on the one hand and atrial natriuretic peptide (ANP) concentrations on the other, during the follicular and luteal phases of spontaneous and gonadotrophin-stimulated ovulatory menstrual cycles. A total of 27 ovulatory women undergoing either a spontaneous (n = 9) or a gonadotrophin-stimulated (n = 18) cycle were selected for inclusion in this study. In comparison with spontaneous cycles, gonadotrophin-stimulated cycles had increased peak follicular oestradiol (mean +/- SE; 937 +/- 150 versus 195 +/- 18 pg/ml; P < 0.05) and midluteal progesterone (mean +/- SE; 44.0 +/- 7.4 versus 14.1 +/- 2.4 ng/ml; P < 0.05) concentrations. There were no differences in the circulating ANP concentrations between the follicular and luteal phases of the menstrual cycle. Despite the increased oestradiol and progesterone concentrations following gonadotrophin stimulation, no difference in ANP concentrations was seen between stimulated and spontaneous cycles. There was no correlation between circulating concentrations of oestradiol, progesterone (at physiological and supraphysiological concentrations) and ANP throughout the menstrual cycle.

Inhibition of human endometrial stromal cell proliferation by interleukin 6.
We investigated the ability of interleukin 6 (IL-6) to modulate human endometrial stromal cell growth in vitro. Stromal cell proliferation in response to treatment with varying concentrations of IL-6 was determined. Endometrial tissue was obtained from 10 normally cycling women during the secretory phase of their menstrual cycle. Treatment with IL-6 resulted in a dose- and cell-density-dependent inhibition of endometrial stromal cell proliferation in vitro. The maximal inhibition was observed with 200 pg/ml of IL-6 and at a concentration of 10(5) cells/well. During in-vitro culture, stromal cells produced low amounts of IL-6 and demonstrated the presence of IL-6 receptor. These data demonstrate that IL-6 acts as a growth-regulatory signal for human endometrial stromal cells. We postulate that IL-6 may contribute to the maintenance of homeostasis in normal endometrium and that perturbation of IL-6 mediated responses may play a role in disorders of the endometrium such as endometrial cancer and endometriosis.

Assisted fertility using electroejaculation in men with spinal cord injury--a review of literature.
OBJECTIVE: To review the effectiveness of rectal probe electroejaculation in terms of pregnancy in treatment of anejaculatory males due to spinal cord injury. The characteristics of electroejaculates also are examined. DATA IDENTIFICATION: All English language studies reporting pregnancies as a result of electroejaculation from men with spinal cord injury and related publications on electroejaculation were identified through MEDLINE search and manual scanning of recent relevant journals. RESULTS: Electroejaculation has become an accepted mode of semen procurement in anejaculatory individuals, with a success rate of approximately 60% to 90% varying among different centers. In general these electroejaculates exhibit high sperm counts but low motility and poor sperm function. Retrograde ejaculation is also common. Pregnancies using electroejaculates have been documented since 1975 in the form of case reports and small series. Assisted reproductive technology recently has been used in conjunction with electroejaculation. Although results are encouraging, pregnancy rates, however, cannot be accurately estimated because of the lack of large series in the literature. CONCLUSIONS: An increasing number of spinal cord-injured patients desiring fertility can achieve pregnancy through combined use of electroejaculation and assisted reproductive techniques. Larger series are needed to establish an accurate pregnancy rate. Elucidation by further studies on etiology of sperm dysfunction of these individuals may improve their prognosis.

Laparoscopic treatment of ectopic pregnancy. Residents' learning experience.
Although operative laparoscopy is a safe and effective method of treating ectopic pregnancy, its widespread acceptance requires appropriate operator training and experience. This retrospective study correlated operative results with experience of the resident performing surgery. Thirteen postgraduate year 3 and 4 gynecology residents treated 60 ectopic pregnancies by laparoscopy. There were four complications: two cases of atelectasis and two of persistent human chorionic gonadotropin titers. There were no blood transfusions. We found that the duration of surgery decreased as operator experience increased, and residents who had experience with five or more cases required a mean operative time of 74 minutes. We conclude from our results that the minimal amount of supervised training necessary for gynecology residents to safety and expeditiously treat ectopic pregnancy laparoscopically is five cases. Furthermore, the minimal morbidity in this study supports our continued recommendation that each resident have prior training experience of at least 10 laparoscopic sterilizations before attempting his or her first case of ectopic pregnancy.

Treatment of cornual obstruction by transvaginal cannulation without hysteroscopy or fluoroscopy.
A new method for relief of cornual obstruction performed totally in the office is presented. We used the Jansen-Anderson catheter with 0.007-cm guide-wire for relief of the obstruction. Ultrasonography is used for demonstrating the position of the catheter and for tubal patency. Subsequent HSG is used for confirmation of tubal patency.

Hydrogynecography: a new technique enables vaginal sonography to visualize pelvic adhesions and other pelvic structures.
Vaginal ultrasonography, done after the transcervical injection of isotonic saline into the cul-de-sac, is a new technique we named hydrogynecography. This was prospectively used in patients suffering from infertility and pelvic pain. In 84% of patients we were able to identify pelvic adhesions confirmed by laparoscopy. In 16% the procedure provided false-negative results.

Histology of midluteal corpus luteum and endometrium from clomiphene citrate-induced cycles.
OBJECTIVE: To determine the histologic development of midluteal corpus luteum (CL) and endometrium in normal fertile women after induction of ovulation with clomiphene citrate (CC). DESIGN, PATIENTS, INTERVENTIONS: Twelve normally cycling women planning to undergo an elective tubal ligation were treated with 50 to 150 mg of CC daily on days 5 through 9 of the cycle. Luteectomy and endometrial biopsy were performed simultaneously 7 days after the urinary luteinizing hormone surge. RESULTS: Because polyovulation occurred in 10 of the 12 women, 22 CL and 12 endometrial biopsies were studied. Ten women had luteal and endometrial histology that were within 2 days of the ovulation to biopsy interval. The 2 remaining women had endometrial histology that lagged 3 days behind the chronological postovulatory date. In these women, out-of-phase endometrium occurred despite polyovulatory cycles in which two and three histologically normal CL lutea were present and associated with elevated progesterone concentrations. CONCLUSIONS: In CC-induced ovulatory cycles: (1) midluteal CL histology is normal and (2) apparently out-of-phase preimplantation endometrium occurs in midluteal phase.

Prospective randomized study of human menotropin versus a follicular and a luteal phase gonadotropin-releasing hormone analog-human menotropin stimulation protocols for in vitro fertilization.
OBJECTIVE: To determine whether gonadotropin-releasing hormone analogs (GnRH-a) initiated either in the luteal phase or in the early follicular phase immediately preceding menotropin will improve the fertilization, implantation, and pregnancy rates (PR) in all IVF patients, when compared with menotropins alone. DESIGN: In a prospective, controlled, randomized study we compared a pure follicle-stimulating hormone (FSH) human menopausal gonadotropin (hMG) protocol (group A = control) (n = 93 cycles) to two protocols in which GnRH-a pretreatment plus pure FSH and/or hMG was used in in vitro fertilization candidates. In group B (n = 64) GnRH-a was initiated during the luteal phase and in group C (n = 35) during the follicular phase. RESULTS: We found (1) no differences in fertilization and implantation rates between the three protocols; (2) similar pregnancy rates per transfer when similar number of conceptus were transferred (A = 30%, B = 22%, C = 21%); (3) an increase of the number of oocytes obtained; and (4) a reduction in the cancellation rate with both GnRH-a protocols. CONCLUSIONS: These findings suggest that there is no obvious superiority between the two GnRH-a protocols in the dosage schedule used and that the major advantage of GnRH-a over non-GnRH-a protocols is in decreasing the cancellation rate and increasing the number of oocytes and conceptus obtained. The follicular phase GnRH-a protocol required less hMG-pure FSH than the luteal phase GnRH-a protocol.

Laparoscopic treatment of painful perihepatic adhesions in Fitz-Hugh-Curtis syndrome.
This report illustrates a case of Fitz-Hugh-Curtis syndrome associated with pelvic inflammatory disease in which the clinical symptom of right upper quadrant pain was severe and persistent despite appropriate antibiotic therapy. Because of the atypical course, an extensive work-up was performed to rule out other possible etiologies for the pain. In this context, a laparoscopy was performed and identified dense adhesions between the liver and the anterior abdominal wall. These adhesions were safely and successfully lysed using a KTP/532 laser through a second puncture site. After surgery the pain was completely resolved, with no further recurrence after 6 months of follow-up.

Effects of human chorionic gonadotropin, prostaglandin F2 alpha and protein kinase C activators on the cyclic AMP and inositol phosphate second messenger systems in cultured human granulosa-luteal cells.
The effects of human chorionic gonadotropin (hCG) and prostaglandin F2 alpha (PGF2 alpha) on the adenylate cyclase-cAMP and inositol phospholipid-phospholipase C-inositol trisphosphate and diacylglycerol transmembrane signalling systems were evaluated in cultured human granulosa-luteal cells. Granulosa-luteal cells obtained from patients undergoing in vitro fertilization were cultured for 72 h prior to addition of hormones. During the last 24 h of culture granulosa-luteal cells were incubated with [3H]inositol. Neither hCG nor gonadotropin-releasing hormone (GnRH) stimulated the inositol phospholipid-phospholipase C signalling system. PGF2 alpha stimulated increases in inositol mono-, bis-, and trisphosphate accumulation in 30 min incubations. NaF (20 mM) mimicked the stimulatory effect of PGF2 alpha on inositol phosphate accumulation suggesting the involvement of a guanine nucleotide regulatory protein in the activation of phospholipase C. In contrast, hCG but not PGF2 alpha or NaF stimulated cAMP accumulation in 30 min incubations. Simultaneous treatment with hCG and PGF2 alpha did not alter the stimulatory effect of PGF2 alpha on inositol phosphate accumulation but reduced (37%) the stimulatory effect of hCG on cAMP accumulation. The protein kinase C activator, 12-O-tetradecanoylphorbol 13-acetate (TPA) inhibited the stimulatory effects of hCG (76%) and PGF2 alpha (62%) on cAMP and inositol phosphate accumulation, respectively. Thus, cultures of human granulosa-luteal cells possess multiple transmembrane signalling systems which may be modulated by the activation of protein kinase C.
