Progesterone therapy to decrease first-trimester spontaneous abortions in previous aborters. 1987

J H Check, and J S Chase, and K Nowroozi, and C H Wu, and H G Adelson

A study was designed to see if the use of prophylactic progesterone vaginal suppositories (PVS) reduced the risk of spontaneous abortions in women with a history of at least one spontaneous abortion. PVS was employed during the luteal phase to the end of the first trimester. The dosage was initially 50 mg/day, but was increased according to the endometrial biopsy and doubled as soon as pregnancy was established. Only 10 women (10%) aborted, and 8 of these 10 were successful in their next PVS-treated pregnancies. Overall there were 12 losses in 132 pregnancies (9%) in these PVS-treated patients. Forty-two percent of untreated controls aborted (10/24). The results suggest that PVS is effective in reducing the risk of spontaneous abortions in high-risk patients.

D011374 Progesterone The major progestational steroid that is secreted primarily by the CORPUS LUTEUM and the PLACENTA. Progesterone acts on the UTERUS, the MAMMARY GLANDS and the BRAIN. It is required in EMBRYO IMPLANTATION; PREGNANCY maintenance, and the development of mammary tissue for MILK production. Progesterone, converted from PREGNENOLONE, also serves as an intermediate in the biosynthesis of GONADAL STEROID HORMONES and adrenal CORTICOSTEROIDS.
