Alterations in xenobiotic-metabolizing enzyme activities across menstrual cycle in healthy volunteers
(2019)The purpose of the study was to determine whether the in vivo activities of drug-metabolizing enzymes CYP1A2 and CYP2A6, xanthine oxidase (XO), and N-acetyltransferase-2 (NAT2) vary across the menstrual cycle. Forty-two ... -
Changes of serum sclerostin and Dickkopf-1 levels during the menstrual cycle. A pilot study
(2016)Studies in postmenopausal women have identified sclerostin as a strong candidate for mediating estrogen effects on the skeleton. The effects of estradiol on sclerostin and Dickkopf-1 in younger women remain unclear. The ... -
The effect of a GnRH antagonist on follicle maturation in normal women
(2019)Research question: Ganirelix is a gonadotrophin-releasing hormone (GnRH) antagonist used for the prevention of premature LH surge during ovarian stimulation. What is the impact of ganirelix on follicle maturation in normal ... -
Effect of exogenous estrogens and progestogens on the course of migraine during reproductive age: A consensus statement by the European Headache Federation (EHF) and the European Society of Contraception and Reproductive Health (ESCRH)
(2018)We systematically reviewed data about the effect of exogenous estrogens and progestogens on the course of migraine during reproductive age. Thereafter a consensus procedure among international experts was undertaken to ... -
The Effect of Metformin on the Endometrium of Women with Polycystic Ovary Syndrome
(2019)Objectives: To investigate the effect of metformin on endometrial receptivity in women with polycystic ovary syndrome (PCOS). Methods: Twenty volunteer women with polycystic ovaries and oligomenorrhea were prospectively ... -
Effect of mifepristone on folliculogenesis in women treated with recombinant FSH
(1997)Objective: To study the mechanism through which mifepristone interrupts folliculogenesis. Design: Normally ovulating women undergoing donor intrauterine insemination (IUI) treatment were investigated during two menstrual ... -
The endocrine effects of multiple folliculogenesis
(2011)Induction of multiple follicular development is a common practice in IVF programmes. Nevertheless, such an approach is not without implications. Apart from the high multiple pregnancy rate, marked changes in the secretion ... -
Gonadotropin Surge-Attenuating Factor: A Nonsteroidal Ovarian Hormone Controlling GnRH-Induced LH Secretion in the Normal Menstrual Cycle
(2018)Gonadotropin surge-attenuating factor (GnSAF) is a nonsteroidal ovarian substance, which attenuates the endogenous LH surge in superovulated women. Different molecular sequences have been found, but only one of them has ... -
Leptin concentrations in normal women following bilateral ovariectomy
(1999)To study the relationships between gonadal steroids and leptin, 20 women with normal cycles were investigated during the postoperative period following a laparotomy. Fourteen women underwent bilateral ovariectomy plus total ... -
Thymidine phosphorylase expression in normal and hyperplastic endometrium
(2000)Aims - To investigate the expression of thymidine phosphorylase (TP), a known angiogenic factor for endothelial cells, in normally cycling endometrium and various forms of endometrial hyperplasia. Methods - TP expression ...
