background :subclinical hypothyroidism may adversely affect in vitro fertilization (ivf) outcomes. however the cutoff of thyroid-stimulating hormone (tsh) for diagnosis and treatment is controversal. the aim of this study was to find the association of clinical pregnancy rate with regard to tsh levels in women undergoing ivf.   methods: a historical cohort study of 816 infertile patients who un...

Serum follicular-stimulating hormone (FSH) and luteinizing hormone (LH) as determined by radioimmunoassay, were correlated with sexual development in 29 patients with hypopituitarism (ages 14.2-29.9 yr).16 of 25 idiopathic hypopituitary patients (20 males and 5 females) exhibited some degree of sexual development. Stage III of sexual development or beyond was achieved by 12 of the 16. Of 13 pat...

Introduction: During the menstrual cycle, women are exposed to continual variations in serum concentrations of various female sex steroid hormones. The fluctuations main hormones, estrogen, progesterone, follicle stimulating hormone and luteinizing hormone, essential for regulating ovulatory cycle patterns. In this sense, it is speculated that strength training can stimulate signaling pathways ...

Serum gonadotropin and estradiol levels were measured in 14 women with regular menses during the early and midfollicular phases. Early follicular follicle-stimulating hormone and, to a lesser extent, luteinizing hormone levels were significantly higher in a group of eight women who had had at least one set of dizygotic twins (six of whom had had two sets) than in a control group of six women wi...

stem cells are generally defined as clonogenic cells capable of both self-renewal and differentiation. probably the best method for long-term preservation of spermatogonial stem cells is cryopreservation. in this study, effects of follicle stimulating hormone and testosterone on viability rate of cryopreserved spermatogonial stem cell after thawing were investigated. sertoli and spermatogonial ...

Serial injections (i.m.) of 10 mg follicle stimulating hormone (FSFI-P) to cheetahs for 5 days followed by human chorionic gonadotropin (hCG, 500 IU) administered on both Days 6 and 7 resulted in ovarian follicle development and/or ovulation in six of seven attempts. One additional female given the same gonadotropin regimen when distinct corpora lutea (CL) were visible on the ovaries failed to ...
