OBJECTIVE To test the hypothesis that the concentration of early follicular phase serum müllerian-inhibiting substance (MIS) is associated with ovarian response in women undergoing ovulation induction in preparation for assisted reproductive technology (ART). DESIGN Retrospective analysis of frozen day 3 serum samples. SETTING Academic ART program. (More)
Semen parameters of raw and prepared (post-swim-up) specimens from 451 cycles of intrauterine insemination (IUI) were analyzed in relation to cycle fecundity in 232 patients undergoing ovarian stimulation with sequential clomiphene citrate/menotropin therapy. Pregnancy occurred in 42 cycles, resulting in an overall pregnancy rate of 17.7%, and a cycle(More)
OBJECTIVE This study was undertaken to evaluate the presence or absence of neurotrophins and their respective receptors within adult human preovulatory follicles. STUDY DESIGN Prospective study of neurotrophins and their receptors in follicular cells and unfertilized oocytes from women undergoing aspiration for in vitro fertilization/intracytoplasmic(More)
Over a 27-month period, the authors observed 70 pregnancies in 66 women following intrauterine insemination (IUI) in conjunction with human menopausal gonadotropins/human chorionic gonadotropin (hMG/hCG) stimulation. Excluding ectopic pregnancies (n = 3) and spontaneous miscarriages (n = 15) during the first 10 weeks of gestation, 14 of the 52 pregnancies(More)
It is a common practice to increase the gonadotropin dose during ovarian stimulation when the estradiol (E2) rise is found to be inadequate. The prognostic impact of the use of this step-up regimen on the outcome of the affected in vitro fertilization (IVF) cycle is the subject of this study. This is a retrospective analysis of IVF cycles in a series of(More)
OBJECTIVE To determine the probability of detecting the gestational sac of a normal intrauterine pregnancy by vaginal ultrasound at different gestational ages and serum hCG concentrations. DESIGN Prospective, randomized study. SETTING Pregnant human volunteers in a university-based clinical research environment. PATIENTS Women with viable pregnancies(More)
The authors examined the hypothesis that active ovulation management would increase the monthly probability of pregnancy occurrence (MPO) in ovulatory women who require intrauterine insemination (IUI). All patients were initially treated during spontaneous ovulatory cycles with IUI performed after the detection of an endogenous lutenizing hormone (LH) surge(More)
We measured the ability of serum from women to stimulate steroidogenesis in cultured granulosa cells. Serum promoted estradiol and progesterone synthesis in proportion to its FHS content measured by RIA [i.e. serum from postmenopausal women (PM) greater than serum from the midcycle at the time of the gonadotropin surge (MC) greater than serum from the first(More)
Neurotrophins are a family of soluble polypeptide growth factors widely recognized for their roles in the mammalian nervous system. One such neurotrophin, brain-derived neurotrophic factor (BDNF) was originally described in the nervous system but has now been shown to be expressed in a variety of nonneuronal tissues including endocrine tissues. We examined(More)
