The steroidogenic capacity and oxidative stress-related parameters of the human corpus luteum (CL) at different stages of the luteal phase were studied under basal and human chorionic gonadotropin (hCG)-stimulated conditions. ...

The present study evaluated the occurrence of apoptosis and caspase-3 activity in the canine corpus luteum during the period of luteal regression in eight pregnant and nine nonpregnant diestrus bitches. Intact luteal cells ...

The GnRH/GnRH receptor system has been found in several extrapituitary tissues, although its physiological significance has not yet been well established. Taking into account that the peripheral neural system can act as a ...

The human corpus luteum is a temporary endocrine gland that develops after ovulation from the ruptured follicle during the luteal phase. It is an important contributor of steroid hormones, particularly progesterone, and ...

New Findings What is the central question of this study? The processes involved in luteal involution have not yet been clarified and, in general, have been studied only from a hormonal point of view. We investigated ...

Context: The natural process of luteolysis and luteal regression is induced by withdrawal of gonadotropin support. Objective: The objectives of this study were: 1) to compare the functional changes and apoptotic features ...

Androstenedione can affect luteal function via a neural pathway in the late pregnant rat. Here, we investigate whether androstenedione is capable of opposing to regression of pregnancy corpus luteum that occurs after ...
