Thyrotropin-releasing hormone (TRH) synthesized in the hypothalamus has the capability of inducing the release of thyroid-stimulating hormone (TSH) from the anterior pituitary, which in turn stimulates the production of thyroid hormones in the thyroid gland. Immunoreactivity for TRH and TRH-like peptides has been found in some tissues outside the nervous system, including thyroid. It has been d...
The frequency of endocrine abnormalities during the follicular phase in non-pregnant women with a history of recurrent abortion was investigated in a case-control study. A total of 42 consecutive women with recurrent spontaneous abortion (three or more consecutive abortions, mean +/- SD: 3.9 +/- 1.1 range 3-8) with no parental chromosome rearrangement or uterine abnormality were studied during ...
Kisspeptin is a key molecule that stimulates gonadotropin secretion via release of gonadotropin-releasing hormone (GnRH). In the present study, our aim was to investigate whether kisspeptin has stimulatory effects on follicular development via GnRH/gonadotropin secretion in cows. Japanese Black beef cows were intravenously injected with full-length bovine kisspeptin [Kp-53 (0.2 or 2 nmol/kg)] o...
introduction: follicle stimulating hormone (fsh) is one of the pituitary glycoproteines that it consists of two subunits alpha and beta. the beta subunit is responsible for the biological activity of fsh. the aim of present study was isolation of the β subunit coding sequence containing its signal sequence from human genome and then cloning of the isolated sequence in ppic9 shuttle vector under...
BACKGROUND Luteinizing hormone (LH) activity in human menopausal gonadotropin (hMG) preparations is derived from human chorionic gonadotropin (hCG) rather than LH. Therefore, we aimed to determine whether there are similarities in the endocrine and follicular profiles of serum and follicular fluid from controlled ovarian stimulation with the recombinant gonadotropins follicle-stimulating hormon...
We present 4 patients with Graves' disease who developed spontaneous hypothyroidism during follow-up. The two most plausible physiopathologic mechanisms for this development were progressive autoimmune-mediated destruction of the thyroid follicular epithelium and a predominance of blocking antibodies to the thyroid-stimulating hormone (TSH) receptor at the expense of stimulating antibodies in t...
Follicular hormone under physiological conditions produced hyperplasia of the muscular wall and proliferation of the mucous membrane of the uterus of rabbits. The following pathological changes were brought about by prolonged application of large doses of the hormone: (a) hyperaemia of the myometrium and the endometrium, with occasional scanty extravasal haemorrhages; (b) glandular-cystic hyper...
Background: To evaluate whether success of fertilization and embryo quality are more probable when follicular fluid Anti-mullerian hormone levels are higher . Materials and Methods: 62 women who underwent IVF cycle were divided into fertilized oocytes group (n=42) and non- fertilized oocytes group (n=20) . Follicular fluid Anti-mullerian hormone levels were measured in both groups. Results: Ant...
