The fact that RU 486 curtailed estrogen-induced endometrial proliferation in primates and relieved pelvic pain in women with endometriosis is the reason for continuing research on antiprogestins. Thirty-two adult female cynomolgus monkeys d…

OBJECTIVE: To study the pharmacodynamic effects of oral micronized P on endometrial maturation. DESIGN: This was a controlled, open, parallel group, pilot study. SETTING: The experiment was performed in an outpatient academic clinical res…

Continuous administration of the antiprogesterone RU486 inhibits ovulation in women and in monkeys; in this regard RU486 may act as a progestin agonist rather than as an antagonist. We compared the site(s) and mechanism(s) of RU486-induced …

OBJECTIVE: To determine whether low (subtherapeutic) doses of gonadotropin-releasing hormone agonists (GnRH-a) can cause ovarian hyperstimulation. DESIGN: The study is in two parts: a preliminary clinical trial of women and a follow-up stu…

GnRH agonist (GnRHa) medications are now routinely used by gynecologists, urologists, medical endocrinologists, and pediatric endocrinologists alike. GnRHa are frequently highly effective in diminishing pain derived from endometriotic lesio…

Recently potent 19-norprogestin derivatives of the RU 486-type were developed. Acting at the receptor level, these steroids are considered a major breakthrough in steroid endocrinology. Clinical studies indicate their potential use in ferti…

There are few objective data to support the clinical impression that pregnancy exerts a beneficial effect on endometriosis. In this study, we examined the progression-regression of endometriosis in pregnant and nonpregnant monkeys. Endometr…

To elucidate the etiology of infertility due to endometriosis, we autografted endometrial or adipose tissue to the pelvic peritoneum of 21 cynomolgus monkeys. These primates were divided into five groups: control animals with adipose tissue…

To study the relationship between peritoneal fluid prostaglandins and infertility associated with endometriosis, we autografted endometrial or adipose tissue to the pelvic peritoneum in 21 monkeys. Peritoneal washings were collected prior t…
