Hormonal regulation of ovarian cellular proliferation

Hormonal regulation of ovarian cellular proliferation.

The steroid hormone estradiol, and the glycoprotein hormones follicle-stimulating hormone (FSH) and luteinizing hormone (LH), are known to be essential for the growth and differentiation of follicles in the ovary. The present study was conducted to determine quantitatively the effects of estradiol, FSH and LH on proliferation of different ovarian cell types (granulosa and theca cells). The imma...

Development and hormonal regulation of the ovarian lymphatic vasculature.

The lymphatic vasculature plays a number of essential physiological roles including maintaining fluid homeostasis, providing a network for the transport of immune cells, and facilitating the uptake of fat-soluble nutrients from the gastrointestinal tract. Although the critical importance and remodeling capacity of the blood vasculature has been well described within the ovary, just a few report...

Male Equivalent Polycystic Ovarian Syndrome: Hormonal, Metabolic and Clinical Aspects

Recent studies identified the presence of a male polycystic ovarian syndrome (PCOS), which mainly affects men whose female relatives are afflicted with PCOS, caused by genes responsible for the susceptibility of this syndrome in women. Similar hormonal, metabolic, and clinical alterations occurring in PCOS women have also been reported in their male relatives, suggesting a association between t...

Characterisation of the Development and Hormonal Regulation of the Ovarian Lymphatic Vasculature

The characteristics of oviposition and hormonal and gene regulation of ovarian follicle development in Magang geese

BACKGROUND Egg laying in Magang geese is characterized by extended interruption between clutches and lowing laying rate. Both the ovarian follicular development and ovulation characteristics, and the associated endocrine and molecular regulatory mechanisms involved are poorly understood, but could be important for guiding development of molecule aided selection of egg laying performances in gee...
