Its mechanism of action included reduction in the levels of gonadotropic
hormones, such as FSH.
In response to the elevated gonadotropic
hormones, his total testosterone--288 ng/dL--was only 72% of the previous therapeutic value.
In our earlier studies carried out on anestrous ewes, we showed that suppressive effect of LPS on GnRH/LH secretion occurs primarily at the level of hypothalamus, changing the gonadotropin-releasing hormone (GnRH) synthesis and release as well at the pituitary level by inhibiting release of LH from gonadotropic
Evaluation of the gonadotropic
ratios among men with varying sperm quality.
Secretion of hypothalamic luteinizing hormone-releasing factor in the hypothalamus and gonadotropic
luteinizing hormone in the pituitary regulate gametogenesis and synthesis of steroid hormones including T in testis.
Purpose: To evaluate the effects of endogenous gonadotropic
hormones (follicle-stimulating hormone, luteinizing hormone) and sex steroids (progesterone, estrogen) to anterior segment parameters.
Upon transport to the pituitary gland, GnRH stimulates the synthesis and secretion of gonadotropic
hormones including follicle-stimulating hormone (FSH) and luteinizing hormone (LH) which following systemic release circulate towards the reproductive organs and subsequently stimulate the release of estrogen and progesterone.
Microscopic examination of pituitary adenoma specimens shows many gonadotropin cells with small secretory granules and, immunohistochemical examination shows pituitary gonadotropic
hormone antibody positivity.
After the maturation pathway of either gender phase has been initiated, gametogenesis as such is not affected, making feminizing estrogenic gonadotropic
interference unlikely to be a significant contributor to the lack of females.
In 1958, commenting on the use of androgens Kistner (26) noted that "androgenic substances, while adequately documented as having produced desirable results in endometriosis, probably exert their effect through inhibition of gonadotropic
substances, although direct effect of the substance upon the endometriotic area has been suggested".
According to Wootton (1990), temperature is the most important environmental factor that affects reproduction in fish, as it modulates the dynamics of the gonadal cycle and influences the secretion of gonadotropic
The development of sensitive and specific antisera and improvements in tissue fixation allow better antigen recognition and gonadotropic
hormones are detected by antisera to [beta]-follicle-stimulating hormone and b-luteinizing hormone in many clinically nonfunctioning adenomas.
