Low-dose progesterone therapy in oestrogenised postmenopausal women: effects on plasma lipids, lipoproteins and liver function parameters.

Authors: Bolaji II, Grimes H, Mortimer G, Tallon DF, Fottrell PF, O’Dwyer EM. Publication Year: 1993 Citation: Eur J Obstet Gynecol Reprod Biol 1993;48(1):61-8.

Subfractions of high-density lipoprotein cholesterol during estrogen replacement therapy: A comparison between progestogens and natural progesterone.

Authors: Ottosson UB, Johansson BG, von Schoultz B. Publication Year: 1985 Citation: Am J Obstet Gynecol 1985;151(6):746-50. Fifty-eight postmenopausal women were followed with respect to subfractions of high-density lipoprotein during 3 cycles of unopposed estrogen. The women received either levonorgestrel, medroxyprogesterone acetate, or natural progesterone during the last ten days of the treatment period. Both …

Natural progesterone, but not medroxyprogesterone acetate, enhances the beneficial effect of estrogen on exercise-induced myocardial ischemia in postmenopausal women.

Preserved forearm endothelial responses with acute exposure to progesterone: A randomized cross-over trial of 17-beta estradiol, progesterone, and 17-beta estradiol with progesterone in healthy menopausal women.

Authors: Mather KJ, Norman EG, Prior JC, Elliott TG. Publication Year: 2000 Citation: J Clin Endocrinol Metab 2000;85(12):4644-9. Regularly menstruating women enjoy relative protection from cardiovascular disease. Until recently, this has been attributed to the function of estrogen, despite the fact that progesterone is also present. This study evaluated the differing acute effects of 17-beta …

The effects of short-term medroxyprogesterone acetate and micronized progesterone on glucose metabolism and lipid profiles in patients with polycystic ovary syndrome: a prospective randomized study.

Authors: Bagis T, Gokcel A, Zeyneloglu HB, Tarim E, Kilicdag EB, Haydardedeoglu B. Publication Year: 2002 Citation: J Clin Endocrinol Metab 2002;87(10):4536-40. This randomized prospective study evaluated and compared the effects of ten days treatment with oral and vaginal micronized progesterone (MP) and medroxyprogesterone acetate (MPA) on glucose metabolism, lipid profiles, and hormonal parameters in …

The proliferation of normal breast tissue implanted into athymic nude mice is stimulated by estrogen, but not by progesterone.

Authors: Laidlaw IJ, Clarke RB, Howell A, Owen AW, Potten CS, Anderson E. Publication Year: 1995 Citation: Endocrinology 1995;136(1):164-71. Normal human breast tissue was implanted subcutaneously into athymic nude mice. The mice were then treated with estradiol or progesterone such that serum levels approximated those seen in normal menstruating women. Immunocytochemical measures were made of …
