Emerging role of GIP and related gut hormones in fertility and PCOS.

Summary of "Emerging role of GIP and related gut hormones in fertility and PCOS."

Gastric inhibitory polypeptide (GIP) is best known as an incretin hormone released by enteroendocrine K-cells in response to feeding and stimulates insulin release to regulate blood glucose and nutrient homeostasis. More recently GIP has been ascribed a positive role in lipid metabolism, bone strength, cardiovascular function and cognition. The present paper considers an emerging role of GIP and related gut hormones in fertility and especially polycystic ovarian syndrome (PCOS). Key evidence concerns restoration of fertility in women with gross obesity and PCOS following bariatric surgery. This is considered to reflect indirect effects mediated by alleviation of insulin resistance together with possible direct effects of surgically induced changes of GIP, GLP-1 and related peptide hormones on ovaries and the hypothalamic-pituitary-adrenal axis. Further studies are required to determine inter-relationships between the hormones and cellular mechanisms involved but these observations suggest that GIP and other gut may provide a novel therapeutic approach for PCOS and other reproductive disorders.

Medical and Biotech [MESH] Definitions

Drugs used to increase fertility or to treat infertility.

Hormones produced by the placenta include CHORIONIC GONADOTROPIN, and PLACENTAL LACTOGEN as well as steroids (ESTROGENS; PROGESTERONE), and neuropeptide hormones similar to those found in the hypothalamus (HYPOTHALAMIC HORMONES).

Hormones produced by the GONADS, including both steroid and peptide hormones. The major steroid hormones include ESTRADIOL and PROGESTERONE from the OVARY, and TESTOSTERONE from the TESTIS. The major peptide hormones include ACTIVINS and INHIBINS.

Hormones released from neoplasms or from other cells that are not the usual sources of hormones.

Those characteristics that distinguish one SEX from the other. The primary sex characteristics are the OVARIES and TESTES and their related hormones. Secondary sex characteristics are those which are masculine or feminine but not directly related to reproduction.
