Prostaglandin D2 stimulates secretion of luteinizing hormone from pituitary gland in vitro.

The effect of prostaglandin D2 on the release of luteinizing hormone was studied in a superfusion system by superfusing human pituitary gland. Perfusion with 30 micrograms of prostaglandin D2 induced a significant increase of luteinizing hormone secretion. This is the first evidence of a direct effect of prostaglandin D2 on the secretion of luteinizing hormone from the human pituitary gland. This finding suggests the possible role of prostaglandin D2 in human reproductive function.
