Growth hormone response to submaximal doses of ghrelin remains unchanged during the follicular phase of the cycle
(2013)
Background: Previous data have shown that ghrelin-induced growth hormone (GH) secretion is augmented in women by exogenous but not by endogenous estrogens. The purpose of this study was to examine the response of GH to ...

It has been reported that increased body mass index (BMI) of men influences fecundity but it is not clear if it impacts on sperm parameters. Whether or not BMI of men influence sperm parameters and subsequently in vitro ...
Angiopoietin-1 and angiopoietin-2 as serum biomarkers for ectopic pregnancy and missed abortion A case-control study
(2013)
Background: A case-control study to evaluate whether a single serum measurement of angiopoietin-1 (ANG-1) and angiopoietin-2 (ANG-2) at 6-8 weeks gestation can differentiate failed pregnancies, whether ectopic pregnancies ...
The Emerging Roles of Adiponectin in Female Reproductive System-Associated Disorders and Pregnancy
(2013)
Adiponectin, the most abundant adipose-released cytokine, has an important role in metabolism, primarily through reducing insulin resistance. Reproductive functions are known to be influenced by energy balance and adiponectin ...
Human ghrelin decreases pituitary response to GnRH in superovulated ewes
(2013)
In addition to its metabolic role, ghrelin has been found to suppress luteinizing hormone secretion in many species acting mainly at the hypothalamic level. The objectives of the present study were to test the hypothesis ...
