The present study was undertaken to analyze the expression pattern of estrogen receptor 1 gene (ESR1) in Barbari bucks (fertile and non-fertile) identified on the basis of seminal quality traits and fertility trials. RNA was extracted from the spleen by Trizol method. The expression pattern of ESR1 gene was analyzed using real time polymerase chain reaction (RT-PCR). The expression pattern of E...
Abstract Background and purpose: Infertility as a major source of stress influences numerous aspects of couples' life like sex and sexual attitude. So the aim of this study was to compare sexual attitude among fertile and infertile couples. Materials and methods: In a cross-sectional study, fifty infertile couples who referred to St.Mary’s infertility center in Sari and fifty fertile coupl...
BACKGROUND Although semen analysis is routinely used to evaluate the male partner in infertile couples, sperm measurements that discriminate between fertile and infertile men are not well defined. METHODS We evaluated two semen specimens from each of the male partners in 765 infertile couples and 696 fertile couples at nine sites. The female partners in the infertile couples had normal result...
Objectives To provide specific estimates of the likely occurrence of the six fertile days (the “fertile window”) during the menstrual cycle. Design Prospective cohort study. Participants 221 healthy women who were planning a pregnancy. Main outcome measures The timing of ovulation in 696 menstrual cycles, estimated using urinary metabolites of oestrogen and progesterone. Results The fertile win...
Two experiments were carried out to examine the interaction of egg storage period, egg position during storage, and turning frequency during subsequent incubation on fertile hatchability and embryonic mortality of broiler hatching eggs. Broiler hatching eggs from breeder flocks at 62 and 60 wk of age were stored for either 3 or 14 d at 18 degrees C and 75% RH in either the normal large end up o...
BACKGROUND L-selectin ligands, localized to the luminal epithelium at the time of implantation, may support the early stages of blastocyst attachment. We have assessed the expression of two L-selectin ligands, defined by MECA-79 and HECA-452 monoclonal antibodies, and the sulfotransferase GlcNAc6ST-2, involved in generation of L-selectin ligand epitopes, in the secretory phase of the endometriu...
