None of the steroids studied were secreted by the ovaries of a postmenopausal woman with the possible exception of androstenedione. While the bulk of the hormones was secreted by the ovary bearing the ripe follicle or the corpus luteum, the data indicate that the contralateral ovary actively ...
The production of sex hormones by congenital hyperplasias or malignancies of the adrenal cortex has long been recognized as suggestive of a biochemical relationship between the adrenal cortex and the gonads. The embryological origin of these tissues from
Estrogens are a specific category of steroid molecules secreted mainly by the ovaries, but also by peripheral steroidogenic conversion, the placenta and by the testes in men. Women have a higher amount of estrogens compared to men. Estrogens promote the development of female genital organs, and ...
To determine whether anti-Müllerian hormone (AMH) is responsible for the gonadal anomalies observed in bovine female "freemartins" united by placental anastomosis to a male twin, fetal rat and ovine prospective ovaries were exposed to purified bovine AMH in organ culture. We show that AMH reprodu...
Luteinizing hormone(LH) is aglycoproteinsecreted by thepituitary glandand, in concert with follicle-stimulating hormone (FSH), plays a central role in reproduction.LHacts directly on the gonads of each sex, binding to its receptor on the surface of the target cells and initiating a cascade of ...
Anti-Mullerian hormone (AMH) is secreted by granulosa cells (GC) in the ovary and is produced in much higher amounts by GCs in women with polycystic ovary syndrome (PCOS). The aim of this project was to examine the role of AMH in the normal ovary and thereby understand the consequences ...
One potential role for JH in adult Drosophila became apparent in studies of fly insulin-like receptor mutants. Drosophila insulin-like receptor (InR) mutants have ovaries similar to those seen in wildtype flies during reproductive diapause [21]. Drosophila reproductive diapause is maintained in part...
Ll: well, it's also a type of glycoprotein hormone secreted by the basophil cells, which is responsible for the formation of the ovulate and the production of progesterone in conjunction with FSH. The FSH increases: the function of the ovaries is so certain ...
The anti-Müllerian hormone (AMH) is a dimeric protein secreted by the female ovaries and has two fundamental roles in follicle genesis. It delays the entr... S Parco,C Novelli,F Vascotto,... - 《International Journal of General Medicine》 被引量: 29发表: 2011年 Epidemiology of infertility...
Freshly dissected ovaries and testes from mice ≥12 weeks of age were fixed in formalin and embedded in paraffin. About 10-μm slices were then cut using a microtome, and stained with haematoxylin and eosin. Samples were imaged using an Olympus CKX41 inverted microscope with a DP21 camera ...
