The Steroid Metabolome in the Isolated Ovarian Follicle and Its Response to Androgen Exposure and Antagonism
The ovarian follicle is a major site of steroidogenesis, crucially required for normal ovarian function and female reproduction. Our understanding of androgen synthesis and metabolism in the developing follicle has been limited by the sensitivity and specificity issues of previously used assays. Here we used liquid chromatography-tandem mass spectrometry to map the stage-dependent endogenous st...
متن کاملOvarian follicle dynamics of female Greater Scaup during egg production
Studies of female waterfowl nutrient reserve use during egg production require a precise understanding of ovarian follicle dynamics to correctly interpret breeding status, and, therefore, derive proper inference. Concerns over numerical declines of North American scaup have increased the need to better understand the role of female condition in reproductive performance. We quantified ovarian fo...
متن کاملThe bovine dominant ovarian follicle.
Central roles in reproductive biology (i.e., growth and development of the oocyte, steroidogenesis, and ovulation) are played by the ovarian dominant follicle (DF). The DF is different from other follicles because it can escape atresia (the fate of all other follicles), and if exposed to the LH surge, its cells will differentiate into the corpus luteum. The DF was originally studied by looking ...
متن کاملOVARIAN STEROID CONCENTRATIONS AND FOLLICLE DEVELOPMENT IN THE FEMALE CAMEL (Camelus dromedarius)
The main objective of the present study was to investigate the changes in ovarian oestradiol and testosterone concentrations as follicles develop in the camel. Ovaries were collected from 15 non-pregnant females from a slaughter house. All follicles ;::::4.0 mm diameter were dissected from each ovary, follicle size was recorded and follicular fluid was aspirated from each follicle and analyzed ...
متن کاملOvarian and adrenal steroid production: regulatory role of LH/HCG.
BACKGROUND The contribution of the adrenal glands to the total circulating steroid pool in women is not well known. There is evidence that human adrenals express the LH receptor gene and that LH may affect adrenal androgen secretion. METHODS HCG stimulation tests (a single dose of 5000 IU i.m.) were performed in women at reproductive age (group 1, n = 6, age 21--39 years) before and after tre...
