RESUMO
OBJECTIVE: Analyse outcome of FSH therapy alone after pituitary desensitization for assisted conception to compare with published results of conventional hMG. DESIGN: Descriptive study of complete series of patients undergoing IVF-ET or GIFT treatment using the chosen drug protocol without exception. SETTING: University private IVF-ET clinic within a comprehensive fertility service. PATIENTS: All couples (n = 773), including 10% > or = 40 years old, treated by IVF-ET or GIFT (1,097 cycles started and 1,012 attempted egg recoveries) for mainly tubal pelvic infective damage (36% of cycles), endometriosis (16%), sperm disorders (14%) and prolonged unexplained infertility (34%) during 3 calendar years, 1990 to 1992. INTERVENTIONS: Ovarian stimulation using FSH alone (urofollitropin, Metrodin; Serono Laboratories Limited, Welwyn Garden City, United Kingdom) after pituitary desensitization using buserelin acetate nasal spray (Suprefact; Hoechst, Hounslow, United Kingdom) from the previous midluteal phase, monitored by ultrasonography and serum E2 measurements, followed by standard IVF-ET or GIFT treatment methods limited to the transfer of no more than three embryos or eggs. OUTCOME MEASURES: Rates per cycle started of cancellation of egg recovery, failure of egg recovery, clinical pregnancy (ultrasound detection of sac), livebirths, and cumulative pregnancy rates (PR) and birth rates. RESULTS: In women < 40 years old and men with favorable sperm (77% of couples and 84% of cycles) the cycle cancellation rate of egg recovery was 7%; attempted egg recovery was successful in every case. For IVF-ET the clinical PR per started cycle and the livebirth rate were 27% and 23%, respectively, and for GIFT 39% and 33%, respectively. The four-cycle cumulative PR by either treatment was 77% and livebirth rate 68%. In women > 40 years old, the cycle PR and birth rate were 14% and 8%, respectively. In cases of sperm disorder the rates in women < 40 years old were 17% and 14%, respectively, and > 40 years old were 18% and 0, respectively. CONCLUSIONS: By comparison with the best worldwide results of assisted conception employing pituitary desensitization, the findings demonstrate that FSH alone to stimulate the ovaries is fully effective and highly successful, and supplementation with LH is not needed.

The most frequently used method for second trimester termination of pregnancy is administration of gemeprost (16, 16-dimethyl-trans delta 2-prostaglandin E1methyl ester) as a vaginal pessary. This provides a safe and effective method for achieving abortion. The current prescribing advice is to insert the pessaries into the posterior vaginal fornix every 3 hours. This study compares this to a 6-hourly regimen. The median abortion interval in the 6-hour group was shorter than the 3-hour group (15 versus 16 hours respectively) but the cumulative abortion rates were similar (98% in the 3-hour group and 91.8% in the 6-hour group). The 6-hour group required a significantly lower total dose of gemeprost to induce abortion. There was no difference in the rates of side-effects in the 2 groups but those receiving pessaries every 6 hours required less analgesia. This study finds no advantage in giving gemeprost every 3 hours.

Transcervical resection of the endometrium (TCRE) is a technique that has gained popularity in gynaecological practice as an alternative to hysterectomy for patients presenting with menstrual disturbances. The advantages of such a technique over traditional hysterectomy include shorter hospital stay, more rapid recovery allowing return to normal daily activity and reduced perioperative morbidity, with associated health and economic benefits.
