Significantly enhanced pregnancy rates per cycle through cryopreservation and thaw of pronuclear stage oocytes.
To examine the results of a 5-year trial using cryopreservation to limit multiple pregnancy and optimize overall pregnancy per cycle. ⋯ Cryopreserved pronucleate oocytes that survive freezing, thawing, and progress through syngamy demonstrate a similar potential for implantation and pregnancy when compared with fresh conceptuses, the cumulative effect of which is an enhanced total PR per cycle.

Effects of a 1-year treatment with a low-dose combined oral contraceptive containing ethinyl estradiol and cyproterone acetate on glucose and insulin metabolism.
To study the effects of the slightly estrogen-dominant monophasic low-dose oral contraceptive (OC) Diane-35 (Schering AG, Berlin, Germany) (35 micrograms ethinyl estradiol [EE2] + 2 mg cyproterone acetate, a 17 alpha-hydroxyprogesterone derivative [17-OHP]) on glucose and insulin metabolism. ⋯ These results suggest that a 1-year treatment with the OC Diane-35, which contains EE2 + a 17-OHP rather than a 19-nortestosterone derivative as the progestogen compound, does not significantly alter peripheral (presumably muscular) insulin sensitivity but slightly increases insulin (presumably hepatic) clearance.

Comparative StudyTransvaginal versus laparoscopic gamete intrafallopian transfer: a case-controlled retrospective comparison.
To compare pregnancy rates (PRs) obtained by transvaginal ultrasound (US)-guided GIFT with PRs from conventional laparoscopy-based GIFT. ⋯ Transvaginal GIFT with present techniques seems to be less effective than laparoscopic GIFT, but it can be considered as a practical alternative to ovarian stimulation and intrauterine insemination and to peritoneal ovum-sperm transfer.

Unilateral obstruction of the vas deferens caused by childhood inguinal herniorrhaphy in male infertility patients.
To study the incidence, diagnosis, and treatment of unilateral obstruction of the vas deferens caused by inguinal herniorrhaphy (IH) during childhood. ⋯ The incidence of vas deferens obstruction was unexpectedly high in subfertile patients with a history of IH during childhood. Careful palpation of the scrotal content was a useful and noninvasive method to diagnose unilateral vas deferens obstruction, and microsurgical vasovasostomy was treatment of choice.

Randomized Controlled Trial Comparative Study Clinical TrialAn open randomized comparative study of the effect of goserelin depot and danazol in the treatment of endometriosis. Zoladex Endometriosis Study Team.
To compare the efficacy and safety of goserelin depot and danazol for endometriosis. ⋯ The monthly administered 3.6-mg depot preparation of goserelin was highly effective at inducing resolution of endometriotic implants and relieving the symptoms of endometriosis with prevention of their return during 24 weeks follow-up in the majority of patients. However, results were not significantly different from those achieved with danazol 600 mg/d.
