The corpus luteum is formed from the open follicle that released an egg during ovulation. Sometimes, the opening seals back up and fluid fills the cavity to form a cyst. This kind of cyst is known as a functional cyst. They are usually benign (not cancerous) and go away on their own....
A corpus luteum cyst can continue producing progesterone. This can last for up to three months when the cyst vanishes. Sometimes, these cysts can burst, causing bleeding into the abdominal cavity (hemoperitoneum). This is more likely and more dangerous in people on blood-thinner drugs. If you...
Chronic exposure of the developing corpus luteum in monkeys to chorionic gonadotropin: persistent progesterone production despite desensitization of adenylate cyclase. The transient steroidogenic response of the macaque corpus luteum to chronic human CG (hCG) treatment beginning on days 9-10 of the luteal...
The influence of episodic LH pulses before and subsequent to ovulation on size and function of the corpus luteum (CL) in cattle was examined. Treatments were 1) control; 2) LHRH antagonist starting 2 days before the preovulatory LH surge (Antagonist [Ant] -2); 3) LHRH antagonist at initia...
Pulsatile progesterone secretion: its relevance to clinical evaluation of corpus luteum function Pulsatile progesterone (P) secretory patterns were characterized in rhesus macaques (n = 13) during the midluteal phase (cycle days 18 to 20) of the normal ovarian/menstrual cycle. Sixty high-amplitude ...

The corpus luteum (CL) undergoes dramatic morphological and functional changes throughout its lifespan. It initially develops from cells that remain in the follicle following ovulation. Eventually the mature CL is composed of multiple, distinctive cell types including steroidogenic cells (small and large...
Relaxin is a polypeptide hormone with structural similarities, both in amino acid sequence and at the DNA level, to insulin and insulin-like growth factors (1). Until recently it has been recognized...doi:10.1007/978-1-4612-3200-1_39Firyal S. Khan-DawoodSpringer New York...
Aglepristone decreased protein for ER during both luteal-stages in CL and uteri. Progesterone receptor protein was decreased by RU354 at Days 6 in the uterus and at Days 11 in CL, whereas RU534 increased PR at Days 11 in uteri. In the CL, RU534 enhanced progesterone production at Days ...
