In the mammalian ovary, the microvasculature in the thecal layer of follicles is associated with follicular development. Apelin and its receptor, APJ, are expressed in the tissues and organs which include the vasculature. The aims of the present stud

Insulin and growth hormone (GH) play critical roles in the process of follicular development and maturation. However, the involvement of insulin receptor (IR) and GH receptor (GHR) during follicular development is not well understood. The aim of this

Dihydrotestosterone (DHT) induces follicular atresia under experimental conditions. However, whether it causes any antagonistic effect under natural condition is not known. In the present study, we investigated concentrations of DHT in follicular flu

The aim of the present in vivo study was to monitor real-time fluctuations of cortisol (Cr) in the wall of preovulatory follicles using a microdialysis system (MDS) implanted in the theca layer as well as changes in ovarian venous plasma (OVP) and ju

Angiogenesis is involved in the local mechanisms that regulate follicular development and ovulation. Recently, the angiopoietin (ANPT)-Tie system has been shown to be required to regulate angiogenesis and blood vessel regression. Expression of the AN

The 5alpha-reduced androgens have been implicated as antagonists of follicular development. In this experiment, we examined the effect of active immunization against 5alpha-reduced androgen on follicular development in ewes. During the breeding seaso

Androgens are products of progestogen metabolism, intermediates in oestrogen biosynthesis and local regulators of ovarian function. Current understanding of intraovarian androgen formation, metabolism and action is reviewed, highlighting the contribu

Local angiogenesis and angiolysis in the corpus luteum (CL) relate to the luteal function. Recent studies indicate that angiopoietins (ANPT) and their receptors Tie regulate remodeling of microvasculature. We therefore examined 1) the relative change
