OBJECTIVE To study the endocrinologic and metabolic effects of metformin in combination with compound cyproterone acetate (CPA) on patients with polycystic ovarian syndrome (PCOS). METHODS A prospective study involved total 45 PCOS patients as group A and 20 non-PCOS infertility patients as control (group B). Complete baseline work-up including body mass index (BMI), waist/hip ratio (WHR), ferriman-Gallwey score (FGS), gonadotrophin, testosterone (T), sex hormone-binding globulin (SHBG), dehydroepiandrosterone sulfate (Ds), insulin (FI) and glucose tolerance test, were performed in all patients. Patients in group A were treated with CPA alone (group A1), metformin alone (group A2) or combination of CPA with metformin (group A3), respectively by randomization. At the end of 12-week therapy, subjects were re-evaluated and above parameters were measured. RESULTS Women in group A had significant increases in BMI, WHR, FGS, luteinizing hormone (LH), T, FI, insulin resistance, and significantly decrease in high-density lipoprotein (HDL)-C comparing with the control group (P < 0.01). No significant difference among A1, A2 and A3 was found at baseline. LH, T, free testosterone (FT) were significant decreased from (13.9 +/- 5.9) IU/L, (2.1 +/- 0.8) nmol/L and (2.8 +/- 2.3) nmol/L respectively to (5.8 +/- 2.2) IU/L, (1.2 +/- 0.4) nmol/L and (0.8 +/- 0.5) nmol/L respectively and SHBG was significant increased from (99 +/- 42) nmol/L to (187 +/- 64) nmol/L in group A3, when compared with LH, T and FT from (13.8 +/- 7.6) IU/L, (2.2 +/- 1.1) nmol/L and (2.5 +/- 1.9) nmol/L respectively to (11.8 +/- 6.5) IU/L, (1.8 +/- 0.8) nmol/L and (1.7 +/- 1.0) nmol/L respectively and SHBG from (99 +/- 40) nmol/L to (120 +/- 51) nmol/L in group A2 (P < 0.05 approximately 0.001). HDL-C were significantly increased from (1.5 +/- 0.3) mmol/L to (1.8 +/- 0.3) mmol/L in group A3 comparing with HDL-C from (1.5 +/- 0.4) mmol/L to (1.6 +/- 0.4) mmol/L in group A1 (P < 0.001). CONCLUSIONS The PCOS patients treated with metformin in combination with compound cyproterone acetate may be more effective in inhibiting hyperandrogen and hypersecretion of LH than metformin alone and more obvious in improving lipid profiles than CPA alone.

D007328 Insulin A 51-amino acid pancreatic hormone that plays a major role in the regulation of glucose metabolism, directly by suppressing endogenous glucose production (GLYCOGENOLYSIS; GLUCONEOGENESIS) and indirectly by suppressing GLUCAGON secretion and LIPOLYSIS. Native insulin is a globular protein comprised of a zinc-coordinated hexamer. Each insulin monomer containing two chains, A (21 residues) and B (30 residues), linked by two disulfide bonds. Insulin is used as a drug to control insulin-dependent diabetes mellitus (DIABETES MELLITUS, TYPE 1).

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.

D008687 Metformin A biguanide hypoglycemic agent used in the treatment of non-insulin-dependent diabetes mellitus not responding to dietary modification. Metformin improves glycemic control by improving insulin sensitivity and decreasing intestinal absorption of glucose.

D011085 Polycystic Ovary Syndrome A complex disorder characterized by infertility, HIRSUTISM; OBESITY; and various menstrual disturbances such as OLIGOMENORRHEA; AMENORRHEA; ANOVULATION. Polycystic ovary syndrome is usually associated with bilateral enlarged ovaries studded with atretic follicles, not with cysts. The term, polycystic ovary, is misleading.

D003687 Dehydroepiandrosterone A major C19 steroid produced by the ADRENAL CORTEX. It is also produced in small quantities in the TESTIS and the OVARY. Dehydroepiandrosterone (DHEA) can be converted to TESTOSTERONE; ANDROSTENEDIONE; ESTRADIOL; and ESTRONE. Most of DHEA is sulfated (DEHYDROEPIANDROSTERONE SULFATE) before secretion.
