Treatment of male infertility due to spinal cord injury using rectal probe electroejaculation: the Israeli experience.

STUDY DESIGN: Male infertility caused by anejaculation is common among patients with spinal cord injury (SCIP). The fertility options for SCIP have improved impressively over the past 10 years. We present the Israeli experience in the treatment of infertility in a large series of SCIP. The issues which are addressed include the treatment of ejaculatory dysfunction, seminal quality and fertility management in SCIP. SETTING: Sexual rehabilitation clinic, Neuro-Rehabilitation department, Sheba Medical Center, Israel. METHODS: Between June 1992 and May 1998, a total of 84 consecutive SCIP were treated in our clinic with electro-ejaculation (EEJ), representing a sample of the SCIP population, composed mostly of young men traumatically injured. The patients have sustained different levels and completeness of spinal injury. Among the patients 33 were interested in achieving pregnancy (39.3%), while the rest were interested in determining fertility potential for family. With EEJ, a low-current stimulation of the ejaculatory organs via a rectal probe is done. The collected semen is used for fertility determination or for fertilization. RESULTS: Eighty-four patients were treated by EEJ. Mean age was 31.3 and mean age at injury was 21.7. There were 29 cervical, 50 thoracic and five lumbar lesions. Sixty-three had complete injury (ASIA A) and 21 incomplete (ASIA B -15, ASIC C -5, ASIA D -1). Fifty-nine had upper motor neuron lesions, and 25 had lower motor neuron. A total of 355 stimulations were performed. Ejaculate was obtained in all patients in 350 stimulations (98.6%), and sperm was present in 74 patients (88.1%) in 296 of the stimulations (83.4%). Fairly good numbers of spermatozoa were obtained, whereas sperm motility and morphology of spermatozoa were low in most cases. A significant difference in sperm count, motility and morphology was noted between antegrade and retrograde samples. No significant improvement in sperm quality after four repeated consecutive stimulations was noted in 38 SCIP. Side effects were minor and encountered in 16 patients (19.1%). Out of 33 couples who wished to achieve pregnancy, 26 reached the stage of insemination. Four pregnancies were achieved after 33 cycles of In-Uterine-Insemination (pregnancy rate 28.6% per couple), and 15 after 68 cycles of In-Vitro-Fertilization (micromanipulation) (pregnancy rate of 68.75% per couple). In all, of 101 conception attempts 23 were successful, resulting in pregnancies in 18 couples, and accounting for an overall pregnancy rate of 70% per couple. CONCLUSION: The high percentage of pregnancies imply that, despite the typically poor sperm motility noted in EEJ, rectal probe EEJ combined with assisted reproductive techniques, and performed by a team approach, is an efficient and safe technique for treating infertility among SCIP.

Inception and Five-year Run of a Semen Cryobank. Clinical and Behavioral Aspects.

Recent developments in infertility treatment, as well as medical and ethical concern to preserve the fertilizing ability of male subjects potentially at risk, led to the inception of a sperm cryobank in our medical center in 1996. Up to the end of the year 2000, 64 young men displaying higher semen values than generally required were accepted as donors, while 305 married (mean age 32.5, range 22-54) and 381 single women (mean age 41.2, range 27-50) were treated by artificial insemination donor (AID), resulting in 251 conceptions. Besides, 437 male subjects aged 15-61 requested sperm cryopreservation. Methodological considerations about sperm cryopreservation, and behavioral implications therefrom, are evaluated.

Dexamethasone as an adjuvant therapy for anovulatory, normoandrogenic patients during ovulation induction with exogenous gonadotropins.

OBJECTIVE: The objective of our study was to explore the effect of dexamethasone (DEX), a highly potent, long-acting glucocorticoid, on the treatment outcome of 74 anovulatory women aged 21 to 29 years, with normal gonadotropins, androgen, and prolactin (PRL) serum levels who failed to conceive on antiestrogen therapy. METHODS: The patients received human menopausal gonadotropin/human chorionic gonadotropin (hMG/hCG) for ovulation induction. Starting on day 4 of the induced menstruation, hMG was administered in combination with DEX, 0.5 mg at night, or without DEX as an adjuvant treatment. The total amount of gonadotropins used, time required for stimulation, percentage of fertilization, serum estradiol levels, pregnancy rate, cumulative pregnancy rate, and abortions were recorded. RESULTS: There were no differences in either the cumulative pregnancy rate (54.1% in the DEX group and 52.7% in the untreated group) or the abortion rates (21.7% in the DEX group compared to 20.8% in the untreated group). The other parameters investigated also did not differ significantly between the groups. CONCLUSIONS: The overall results did not support DEX as a clinically useful adjuvant therapy for anovulatory, normoandrogenic patients.

Spontaneous pregnancies despite failed attempts at ovulation induction in a woman with latrogenic premature ovarian failure.

BACKGROUND: Women with premature ovarian failure may conceive spontaneously or following different regimens of ovulation induction. CASE: A 29-year-old woman with eight years of hypergonadotropic hypogonadism following chemotherapy and radiotherapy for Hodgkin's disease conceived spontaneously and spontaneously aborted after discontinuation of estrogen replacement. Subsequently she underwent pituitary gonadotrope downregulation and attempted controlled ovarian hyperstimulation without an ovarian response or follicular development. Despite this failure, she conceived spontaneously on two occasions, resulting in a live-born infant and an ongoing pregnancy. CONCLUSION: Cases of hypergonadotropic hypogonadism may not be permanent or irreversible. Interventional regimens may fail to induce ovulation despite the presence of residual oocytes capable of recruitment and fertilization.

Clinical, hormonal and sonographic predictors of successful RU-486-induced abortions.

To evaluate which method, clinical, hormonal or sonographic, can be used as the best predictor of successful RU-486-induced abortions, 20 healthy women with fetal cardiac activity, between 6 and 9 weeks from the last menstrual period and desiring abortion, were studied. Fourteen women (70%) successfully aborted, and 6 (30%) failed to abort within 7 days following therapy. A small hematoma, seen as a localized detachment of the gestational sac, was observed in the decidua capsularis in women who aborted successfully. A significant decrease in plasma levels of estradiol and progesterone (p < 0.04) and significantly increased cortisol levels (p < 0.001) in the plasma of the 14 patients who aborted were noted by the 7th day following treatment. No significant changes were observed in the 6 nonaborting patients. In conclusion, the differences in the early sonographic findings may be helpful in the early prediction of successful RU-486 administration.

Successful pregnancy outcome with combination therapy in women with the antiphospholipid antibody syndrome.

Four women with the antiphospholipid syndrome associated with lupus anticoagulant and a poor obstetric history were treated with a combination of glucocorticosteroids, anticoagulants and platelet inhibitor therapy. All patients had at least one previous miscarriage while receiving prednisone and low-dose aspirin. The treatment regimen included: aspirin, dipyridamole, prednisone, and warfarin or heparin. This treatment resulted in a successful pregnancy outcome in all cases, without preeclampsia or recurrence of thrombosis. One patient developed a vertebral compression fracture while receiving heparin and prednisone. Two pregnancies required cesarean delivery for fetal distress at 32 and 34 weeks. All four infant birth weights were appropriate for the gestational age. This regimen may be a therapeutic option for patients with the antiphospholipid antibody syndrome, especially if they have failed other commonly used treatments.

Lupus anticoagulant. Significance in habitual first-trimester abortion.

Therapy with steroids and aspirin has been reported to benefit pregnancies in patients with lupus anticoagulant (LA). In this study, habitual first-trimester aborters with LA using steroids and aspirin were compared to a control group of untreated habitual aborters without LA. In habitual aborters with LA, 12 of 24 (50%) pregnancies reached the second trimester as compared to 8 of 22 pregnancies (36%) in the control group. Since the treated group did no better than the control group, LA probably is not a cause of first-trimester abortion. However, once the second trimester is reached, a 50% incidence of growth retardation was found, and 42% of fetuses died in the second or third trimester in treated LA patients. Treatment with steroids and anti-platelet aggregating agents may be necessary despite the attendant risks to prevent those sequelae in the second and third trimesters. There was a 29% live birth rate in treated LA patients; the rate was 36% in control patients. However, this rate was produced only by early intervention, which was unnecessary in the control patients.

Toxic shock syndrome after loop electrosurgical excision procedure.

Toxic shock syndrome can occur after any surgical procedure. We report the first case of toxic shock syndrome that has occurred after a loop electrosurgical excision procedure. The patient recovered with supportive care and antibiotics.

[Falloposcopy--a new method for evaluation and treatment of infertility due to tubal factors].

Tubal factors cause infertility in about a third of cases. With current diagnostic techniques, such as laparoscopy and hysterosalpingography, only a fraction of the causes of tubal infertility can be diagnosed and in many cases misdiagnosis results. Newer methods, such as ampullosalpingoscopy enable examination of the fimbria and ampullar segment of the fallopian tube, but the examination of the proximal tube, in which 10-20% of occlusions occur, is still impossible. We describe a new diagnostic technique, falloposcopy. It involves the transuterine insertion of a fiber optic device into the fallopian tube through a hysteroscope. This technique enables direct visualization of all segments of the fallopian tube, as well as removal of intratubal debris or adhesions. Using falloposcopy, a new grading method for tubal disease has been developed. We describe the results of 129 falloposcopic procedures in 82 women. Following falloposcopy, women with mild to moderate disease, according to the new classification, have conceived without further therapy during a follow-up period of up to 3 years. Falloposcopy may aid in differentiating between patients suitable for tubal surgery and those who should be referred for in vitro fertilization.

Effect of intraumbilical prostaglandin F2 alpha injection on the third stage of labor.

The effect of an intraumbilical prostaglandin (PG) F2 alpha injection on the third stage of normal labor was studied in 54 normal, laboring women at term. Either 1 mg of PGF2 alpha diluted to 20 mL in normal saline (27 women) or 20 mL of normal saline alone (27 women) was injected into the umbilical vein immediately after delivery using a randomized, double-blind protocol. The mean (+/- SD) duration of the third stage was 7.31 +/- 6.37 minutes in the PGF2 alpha patients and 8.94 +/- 7.10 in the normal saline patients. Intraumbilical PGF2 alpha did not influence the third stage of normal labor.

The effect of gonadotropin-releasing hormone agonist on the ovarian response and in vitro fertilization results in polycystic ovarian syndrome: a prospective study.

OBJECTIVE: To assess the effect of gonadotropin-releasing hormone agonist (GnRH-a) on pituitary suppression, subsequent ovarian response, and results of in vitro fertilization (IVF) treatments in polycystic ovarian syndrome (PCOS) patients. DESIGN: Randomized prospective study. SETTING: In vitro fertilization program and endocrinologic institute. PATIENTS: Thirty patients with PCOS; 16 received GnRH-a, and 14 did not receive GnRH-a. INTERVENTIONS: Ovum pick-up and embryo transfer. MAIN OUTCOME MEASURES: Response to GnRH-a test, serum and follicular fluid (FF) hormonal measurements, steroid levels, and aromatse activity in granulosa cell (GC) culture, and results of IVF. RESULTS: Pituitary responsiveness was abolished in all patients 14 days after GnRH-a administration, and early luteinization was prevented. Steroid levels in FF did not differ between the two groups. In GC culture, progesterone (P) levels were higher in patients without the GnRH-a (3,704 +/- 1,232 nmol/L versus 2,117 +/- 235 nmol/L; P less than 0.05) as were androstenedione (A) levels (5.3 +/- 1.0 nmol/L versus less than 3.5 nmol/L; P less than 0.05). However, aromatase activity and IVF results were similar in the two groups. CONCLUSIONS: Administration of GnRH-a in patients with PCOS decreases P and A production by the GC cells and prevents early luteinization. It does not affect the IVF results.

Curettage vs. nonsurgical management in women with early spontaneous abortions. The effect on fertility.

Among 114 women with early spontaneous abortions, low beta-human chorionic gonadotropin levels and no ultrasonographically demonstrable residual tissue in the uterine cavity, 68 underwent uterine curettage, and 46 were managed conservatively. No complications, such as bleeding or infection, were observed in either group, and the probability of conception, outcome of subsequent pregnancies and rate of subsequent abortions were similar. Curettage offers no advantage over conservative management in selected patients with early abortions.

Spontaneous pregnancies in two women with Laron-type dwarfism: are growth hormone and circulating insulin-like growth factor mandatory for induction of ovulation?

It has recently been claimed that growth hormone (GH) and insulin-like growth factors have a role in follicular development; different mechanisms of action have been proposed. Of late, many investigators have been led by these findings to use GH and growth hormone-releasing hormone (GHRH) for induction of ovulation, in combination with human menopausal gonadotrophins. It is, however, still doubtful whether or not growth hormones and/or insulin-like growth factors are mandatory for follicular development and fertility. In this study we describe two women with Laron-type dwarfism who lacked insulin-like growth factors and who had spontaneous pregnancies. We also discuss different natural defects in the production and metabolism of growth hormone and insulin-like growth factors in humans, and the fertility performance of the affected females. It is our assumption that GH and systemic insulin-like growth factors may modulate follicular development, but that they are not necessarily mandatory for ovarian follicular development.

Pelvic malignancy presenting as a pelvic inflammatory process in pre and postmenopausal women.

Among two hundred and twenty-one patients admitted with the diagnosis of pelvic inflammatory disease (PID), 6 had an underlying malignancy. The rate of underlying malignancy was 1.4% in premenopausal patients and 42.8% in postmenopausal patients. This difference was statistically significant, p less than 0.001. In postmenopausal patients presenting with a pelvic inflammatory process pelvic malignancy should be highly suspected and thorough examination made.

Oxytocin or saline injected intra-umbilically did not influence the third stage of labor.

The injection of varying volumes of normal saline solution, alone or with oxytocin, into the umbilical vein immediately after delivery was studied in 125 normal women delivered at term. Thirty seconds after cord clamping, either 20 ml (group 1, n = 25 women), 30 ml (group 2, n = 25) or 40 ml (group 3, n = 25) of normal saline solution alone, or oxytocin 10 units in 20 ml saline solution (group 4, n = 25) or oxytocin 10 units in 40 ml saline solution (group 5, n = 25) were injected into the umbilical vein 1 cm from the introitus just proximal to the umbilical clamp. The mean (+/- SD) duration of placental expulsion was similar in the five study groups. We conclude that neither the volume of the solution nor the oxytocin injected intra-umbilically has any effect on the duration of the third stage of normal labor.

Follicular and luteal cysts after treatment with gonadotropin-releasing hormone analog for in vitro fertilization.

Ovarian cysts are a common complication of GnRH-a administration. We followed 98 patients who were suppressed with GnRH-a before ovarian stimulation with hMG for IVF treatment. Approximately 20% of the patients receiving GnRH-a during the follicular or luteal phase had developed ovarian cysts. However, the number of cysts per patient was significantly higher in the follicular phase compared with luteal phase. Systematic aspiration of those cysts under local anesthesia permitted the start of ovarian stimulation with hMG as scheduled on day 16 after GnRH-a administration. Follicular fluid content of the cysts revealed similar levels of steroids to those in normal follicles. These cysts contained few cells and no egg. In vitro fertilization treatment was more successful in patients whose cysts were aspirated during the luteal phase than in those with cysts during the follicular phase. We concluded that luteal phase cysts are more benign than follicular phase cysts, and it is possible that they represent an enlargement of pre-existing corpora lutea.
