= Abstract = Follicular fluids and their matched oocytes were obtained from 16 follicles of 7 women who conceived after in vitro fertilization(IVF), and 49 follicles of 17 women who failed to conceive after the procedure. Follicular development was induced with a combination of follicle-stimulating hormone and human menopausal gonadotropin. There was no significant difference in follicular cycl...

background: azadirachta indica is a tree with most of the parts having various medicinal values. it is however popular because of its high potencies, as antimalarial and anti-fertility agents, which the locals still exploit. objective: we investigated the effect of the methanol leaf extract on the serum levels of the pituitary-gonad hormones and the histo-morphology of the ovary and uterus of a...

OBJECTIVE To determine whether multiple ovulation in mothers of spontaneous dizygotic (DZ) twins is because of higher hypothalamic stimulation or is in response to lower serum levels of ovarian inhibin. DESIGN Serum hormone levels were measured at five times throughout the cycle in a sample of eight mothers of DZ twins and paired controls. On day 12, ovarian ultrasonography was performed. S...

background: the increase in the rate of infertility in women has prompted the need to search for plants with antifertility potentials. objective: the effect of administration of aqueous extract of cnidoscolous aconitifolius leaves for seven days on reproductive hormones of female wistar rats was investigated. materials and methods: sixty female albino rats were grouped into four (a, b, c and d)...

Inhibin is a gonadal hormone that inhibits the release of follicle stimulating hormone (FSH) from the anterior pituitary gland. The objective of this study was to determine whether active immunization of male and female rats against inhibin rich, steroid-free bovine follicular fluid would increase inhibin antibody titre, onset of female puberty, pregnancy rate, litter size, testis weights, test...

Advances in assisted reproduction techniques and the treatment of diseases known to be correlated with infertility such as polycystic ovary syndrome and premature ovarian failure require a better understanding of ovarian physiology. Despite the enormous quantity of information produced over the last two decades, the mechanisms controlling follicular development are not fully understood. Ovarian...

Insulin-like growth factor-I (IGF-I) and IGF binding protein-3 (IGFBP-3) play an important role in regulating follicle growth and maturation. We have evaluated whether responsiveness to gonadotrophins during an in-vitro fertilization (IVF) treatment is related to follicular fluid IGF-I and IGFBP-3 concentrations. We also investigated if a difference is present in IGF-I and IGFBP-3 concentration...

OBJECTIVE The objective of this study was to evaluate the relationship between oocyte yield, fertilization, and clinical pregnancy (CP), and anti-Mullerian hormone (AMH) level in serum and follicular fluid during in vitro fertilization treatment. METHODS Forty-four infertile women who underwent IVF treatment using multiagonist protocol were included in this study. Baseline level of AMH in ser...

OBJECTIVE To investigate the relationship between serum concentrations of inhibin A, inhibin B and estradiol (E(2)) and the number of developing follicles during the administration of exogenous follicle-stimulating hormone (FSH) in various regimens in normo-ovulatory volunteers and to evaluate if inhibins act as suitable markers for the number of developing follicles during ovarian stimulation....

The changes in serum levels of luteinizing hormone (LH), follicle-stimulating hormone (FHS), estradiol, and progesterone that occur both early and late in reproductive life were characterized and compared with findings in young, normal women and in patients with certain menstrual disorders. A total of 50 complete menstrual cycles in 37 were examined. Five distinct patterns of hormonal regulatio...
