Acetone extract of Stem of Ocimum gratissimum was screened for the antifertility activity in proven fertile female albino rats at the doses 100, 200 and 500 mg/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 lapa...

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...

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...

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...

A heterologous ELISA for measurement of osteocalcin (bone Gla-protein) is described, involving biotinylated bovine osteocalcin and polyclonal antibodies. The log-linear range was 2.3-37.5 micrograms/L. Between-run (total) and within-run CVs (n = 10) were 5.7-6.4 and 5.9-6.1%, respectively; analytical recoveries ranged from 92% to 108%. Comparison of our method (x) with an RIA (y) yielded y = 1....

Background: Having low-grade chronic inflammation state symptoms such as elevated C-reactive protein and interleukin-6 play a crucial role in polycystic ovary syndrome (PCOS). Green tea has antiinflammatory properties. This research evaluates the effect of green tea on inflammatory indexes. Adult Wistar rats were exposed to subcutaneous administration of estradiol valerate for PCOS induction. P...
