Petroleum ether extract of seeds of Cassia fistula was screened for the antifertility activity in proven fertile female albino rats at the doses 100, 200 and 500mg/kg b.wt./day. Oral administration of the extract to mated female rats on days 1-5 of pregnancy resulted in a decline in the fertility index, numbers of uterine implants and live fetuses in a dose dependent manner as was confirmed by ...

BACKGROUND Polycystic ovary syndrome (PCOS) is one of the most common hormonal disorders that can lead to irregular menstrual cycles and hyperandrogenism. Reduced levels of progesterone and increased estrogen in these women can perpetually stimulate the endometrial tissue of the uterus. In this study, we assess the effect of PCOS induction by estradiol valerate (EV) in a rat model. MATERIALS ...

background: endometrial integrin expression changes might be a reason for implantation failure in polycystic ovarian syndromes (pcos). objective: assessment of integrin genes and proteins expression upon endometrium in the pcos experimental mouse model was the main goal of this study. materials and methods: 30 nmri female mice were equally divided into control, experimental (pcos; received estr...

Detection of estrogenic disrupting compounds (EDCs) in drinking waters around China has led to rising concerns about health risks associated with these compounds. There is, however, a paucity of studies on the occurrence and identification of the main compounds responsible for this pollution in the source waters. To fill this void, we screened estrogenic activities of 23 source water samples fr...

background: poly cystic ovary syndrome is one of the most common female endocrine disorders. one of the side effects of pcos is oxidative stress.. here we investigated antioxidants effects of thymus vulgaris ethanoli extract on experimental pcos induced rats by estradiol-valerat (ppa). methods : wistar female rat (n=70) were divided into 7 groups including c1: an equal volume of (0.9% nacl) as ...

objective:  to investigate the reproductive outcome of artificial endometrial preparation with exogenous steroids for frozen-thawed embryo transfer with and without pre-treatment with depot gonadotropin releasing hormone agonist (gnrh-a) in women with regular menses. amaterials and methods: this is a prospective randomized clinical trial conducted in two rt centers on 176 women undergoing froze...

OBJECTIVE To evaluate the predictive efficiency of serum estradiol (E2) concentration in the mid-luteal phase regarding chemical, clinical, and ongoing pregnancies, in patients subjected to IVF/ICSI with fresh embryo transfer. METHODS One hundred and forty-three patients undergoing IVF/ICSI met all the inclusion criteria for the present study. Most of the patients used antagonists, final matu...

Background. Heavy menstrual bleeding (HMB) is a common gynecological complaint affecting quality of life. Objectives. To assess knowledge on diagnosis and treatments of HMB of Latin American (LA) obstetricians and gynecologists (OBGYNs). Methods.

Seventy postpuberal dairy heifers were assigned to remain untreated (n = 26) or to receive the Syncro-Mate-B (SMB) treatment (n = 44). Untreated heifers were inseminated at 12 hr after detection of estrus, while SMB-treated heifers were inseminated either at 48 hr after implant removal (group 1) or at 12 hr after detection of estrus (group 2). Jugular blood was collected at regular intervals fr...
