The existence of inhibitory short- and ultrashort-loop feedback mechanisms for luteinizing hormone (LH), while documented in animals, has been questioned in humans. Since human chorionic gonadotropin (hCG) binds to LH receptors but can be distinguish

The hormonal response to clomiphene citrate (CC) has been used to evaluate ovarian reserve. In the current study, we tested the reproducibility of response to 100 mg of CC administered for 5 days in a group of 20 women, 35 to 40 years of age, with re

Adult rats exposed to prenatal alcohol were evaluated for their susceptibility to either hormone- or chemical-inducing tumors. In the first study, rats exposed to prenatal alcohol displayed an increased propensity to β-estradiol (E 2 )-induced adeno

The pharmacokinetics of human chorionic gonadotropin (hCG) was studied in 15 normal volunteers and 15 patients undergoing in vitro fertilization (IVF). Each subject received 6000 IU hCG, intramuscularly (im), at midcycle, and serum was assayed for hC

A study was undertaken to compare the hormonal parameters [serum concentrations of estradiol (E2), and progesterone (P) and P/E2 ratios] of patients undergoing in vitro fertilization/embryo transfer to whom either progesterone in oil or human chorion

Fifteen ovulatory patients undergoing ovarian stimulation with clomiphene citrate-human menopausal gonadotropin-human chorionic gonadotropin (hCG) for in vitro fertilization were studied. All 15 attained peak estradiol (E2) levels of greater than 600

Testicular regression was induced in adult hamsters by optic enucleation, short photoperiod, or melatonin injections. The melatonin injected group, while undergoing testicular regression, showed a quite different time course from the optic enucleated

Sertoli cells isolated from immature, adult, and adult optic-enucleated hamsters respond to FSH, but not to LH, with an increase in cAMP accumulation. There is an age-related decline in responsiveness of Sertoli cells to FSH. Sertoli cells cultured f

FSH beta in the medium and extracts of cultured rat anterior pituitary cells was quantitated with a heterologous radioimmunoassay utilizing anti-rFSH beta and hFSH beta as the standard and tracer. After 4 days in culture, extracts were prepared from

In an attempt to improve the pregnancy rate following in vitro fertilization and embryo transfer by increasing the numbers of embryos available for transfer to each patient, a prospective, randomized comparison of clomiphene citrate alone (50 mg/day,
