The purpose of this investigation was to assess the chronic effects of marihuana smoking on the basal and stimulated secretion of the pituitary hormones luteinizing hormone (LH), follicle-stimulating (FSH) and prolactin (PRL). Ten male chronic marihuana users and 10 age- and sex-matched healthy volunteers were studied by measuring hormone levels before and after i.v. administration of thyrotropin releasing hormone (TRH) and gonadotropin releasing hormone (GnRH). The basal and stimulated levels of LH were reduced in marihuana users, whereas FSH and PRL levels and responses were not different from the control subjects. The chronic use of marihuana may selectively impair the hypothalamic control mechanisms regulating LH secretion.

D007986 Luteinizing Hormone A major gonadotropin secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Luteinizing hormone regulates steroid production by the interstitial cells of the TESTIS and the OVARY. The preovulatory LUTEINIZING HORMONE surge in females induces OVULATION, and subsequent LUTEINIZATION of the follicle. LUTEINIZING HORMONE consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the three pituitary glycoprotein hormones (TSH, LH and FSH), but the beta subunit is unique and confers its biological specificity.

D011388 Prolactin A lactogenic hormone secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). It is a polypeptide of approximately 23 kD. Besides its major action on lactation, in some species prolactin exerts effects on reproduction, maternal behavior, fat metabolism, immunomodulation and osmoregulation. Prolactin receptors are present in the mammary gland, hypothalamus, liver, ovary, testis, and prostate.

D005640 Follicle Stimulating Hormone A major gonadotropin secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Follicle-stimulating hormone stimulates GAMETOGENESIS and the supporting cells such as the ovarian GRANULOSA CELLS, the testicular SERTOLI CELLS, and LEYDIG CELLS. FSH consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the three pituitary glycoprotein hormones (TSH, LH, and FSH), but the beta subunit is unique and confers its biological specificity.
