Prostaglandin secretion by human endometrium in vitro
American Journal of Obstetrics and Gynecology
|March 15, 1982
Summary
Human endometria produce prostaglandins (PGs). Gonadal steroids regulate prostaglandin F (PGF) production, and mefenamic acid inhibits PGF and prostaglandin E (PGE) secretion, supporting its use for dysmenorrhea.
Area of Science:
- Reproductive Endocrinology
- Gynecology
- Pharmacology
Background:
- The human endometrium produces prostaglandins (PGs), key mediators in reproductive processes.
- Prostaglandin F (PGF) and prostaglandin E (PGE) are implicated in endometrial function and dysmenorrhea.
Purpose of the Study:
- To investigate the regulation of endometrial PGF and PGE secretion by 17 beta-estradiol and progesterone.
- To determine the effect of mefenamic acid on endometrial PGF and PGE production.
Main Methods:
- Human endometrial organ culture from proliferative and secretory phases.
- Treatment with 17 beta-estradiol, progesterone, and mefenamic acid.
- Measurement of PGF and PGE secretion in culture.
Main Results:
- 17 beta-estradiol increased PGF secretion in both endometrial phases.
- Progesterone inhibited PGF secretion in proliferative endometrium but not secretory.
- Mefenamic acid significantly inhibited secretion of both PGF and PGE.
Conclusions:
- Endometrial PGF production is regulated by gonadal steroids.
- Mefenamic acid's mechanism in treating dysmenorrhea likely involves inhibiting endometrial prostaglandin synthesis.
