Significance of 17alpha OH progesterone assay in the evaluation of ovarian and adrenal function. 1976

V M Jasonni, and C Melega, and G Possati, and M S Preti, and P Crea, and S Lodi, and C Flamigni

Plasma 17alpha OH progesterone was assayed radioimmunologically, using an anti-17-OH-progesterone BSA antiserum as specific binding antigen. The method consisted in extracting steroids with ethyl ether from 1 ml plasm (to which 17alpha OH progesterone-1,2-3H had been added for the assessment of losses); the extract was then submitted to chromatography on a Sephadex LH-20 column, antiserum was added and the free steroid was separated from the bound form by Charcoal-dextran. Average recovery of 17alpha OH progesterone-1,2-3H was 75+/-5%. Minimum sensitivity of the method oscillated about 7-10 pg. MIF (Method Interfering Factors) were evaluated. The method was used for the assay of 17alpha OH progesterone plasma levels during normal menstrual cycles, in women undergoing ovarian stimulation with HMG and HCG in the follicular and luteal phase respectively. Finally, changes of plasma 17alpha OH progesterone levels were assessed during adrenal stimulation and suppression in various stages of the menstrual cycle.

UI MeSH Term Description Entries
D008596 Menotropins Extracts of urine from menopausal women that contain high concentrations of pituitary gonadotropins, FOLLICLE STIMULATING HORMONE and LUTEINIZING HORMONE. Menotropins are used to treat infertility. The FSH:LH ratio and degree of purity vary in different preparations.

D008598 Menstruation The periodic shedding of the ENDOMETRIUM and associated menstrual bleeding in the MENSTRUAL CYCLE of humans and primates. Menstruation is due to the decline in circulating PROGESTERONE, and occurs at the late LUTEAL PHASE when LUTEOLYSIS of the CORPUS LUTEUM takes place.

D006063 Chorionic Gonadotropin A gonadotropic glycoprotein hormone produced primarily by the PLACENTA. Similar to the pituitary LUTEINIZING HORMONE in structure and function, chorionic gonadotropin is involved in maintaining the CORPUS LUTEUM during pregnancy. CG consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is virtually identical to the alpha subunits of the three pituitary glycoprotein hormones (TSH, LH, and FSH), but the beta subunit is unique and confers its biological specificity (CHORIONIC GONADOTROPIN, BETA SUBUNIT, HUMAN).
