Alcohol effects on luteinizing hormone releasing hormone-stimulated anterior pituitary and gonadal hormones in women.

Plasma luteinizing hormone (LH), follicle stimulating hormone (FSH), prolactin, estradiol (E2) and progesterone were measured in 24 normal, adult women before and after i.v. administration of 100 micrograms luteinizing hormone releasing hormone (LHRH; Factrel) and p.o. ingestion of an alcohol (0.694 g of alcohol per kg b.wt.) or placebo solution. Twelve subjects were studied during the early follicular phase of the menstrual cycle and 12 subjects were studied during the midluteal phase of the menstrual cycle. During each menstrual cycle phase, six subjects received placebo solution and six subjects received alcohol solution administered under double-blind conditions. Mean peak blood alcohol levels of 113 to 122 mg/dl were measured 45 to 60 min after initiation of alcohol intake. LHRH stimulated a significant increase in LH after both alcohol (P less than .0001) and placebo (P less than .0001) administration, and this LH increase was equivalent during the follicular and the luteal phases of the menstrual cycle. LHRH also stimulated a significant increase in FSH levels after both alcohol and placebo intake during the follicular and luteal phases of the menstrual cycle (P less than .0001). There were no significant differences in LHRH-stimulated FSH between the alcohol and placebo conditions. Plasma prolactin levels also increased significantly after LHRH administration during the follicular and luteal phases of the menstrual cycle (P less than .0001). There were no significant differences in prolactin response to LHRH administration between the alcohol or placebo conditions during the follicular and luteal phases of the menstrual cycle. Plasma E2 levels did not increase significantly after LHRH administration and placebo alcohol during the follicular phase of the menstrual cycle.(ABSTRACT TRUNCATED AT 250 WORDS)
