High impact information on FSH

Results: VPA, but not LEV, caused a significant increase of LH-stimulated testosterone secretion and decreased FSH-stimulated estradiol secretion [1].
VPA decreased conversion of testosterone to estradiol in both basal and FSH-stimulated cultures, while LEV only decreased testosterone to estradiol conversion after FSH stimulation and only at the highest, nontherapeutic drug concentration [1].
Addition of the combination of FSH, LH and PRL during the period of oocyte maturation marginally improved male pronuclear formation rates (41.3 vs 55.6%; P=0.06) [2].
FSH-stimulated follicular secretions enhance oocyte maturation in pigs [2].
Despite the marked cumuli expansion induced by gonadotropins, uridine uptake was not influenced by LH or FSH [3].

Biological context of FSH

This treatment lowered the preovulatory surge of LH and FSH, but it did not alter serum estradiol-17beta concentrations, the proportion of pigs exhibiting estrus, or the ovulation rate [4].
Identification of differential gene expression in in vitro FSH treated pig granulosa cells using suppression subtractive hybridization [5].

Anatomical context of FSH

FSH, which binds to specific receptors on granulosa cells in mammals, plays a key role in folliculogenesis [5].
The increase of estrogens was not paralleled by a similar increase of FSH and LH but was related to the increase of the total number of Leydig cells [6].
Concentrations of estrogens, testosterone, FSH, and LH were measured in blood plasma [6].
Immunohistological detection of LH and FSH in the pituitary gland of treated and control boars showed no quantifiable difference in the amount of these two gonadotropins and no lesions were visible in the hypothalamus and the pituitary gland [7].

Associations of FSH with chemical compounds

By contrast, choline uptake in LH-treated oocytes was significantly higher than in FSH-treated or control oocytes (3199 cpm +/- 251 vs 1686 cpm +/- 142, P<0.01) [3].
FSH, LH and progesterone did not change with age [8].

Analytical, diagnostic and therapeutic context of FSH

To study the developmental characteristics of Meishan pigs, the plasma concentrations of LH, FSH, inhibin, testosterone, estradiol-17beta, progesterone and insulin-like growth factor-I (IGF-I) in young Meishan boars were determined using RIA and ELISA [8].
