Within the PREVIENI project, infertile and fertile women were enrolled from metropolitan, urban and rural Italian areas. Blood/serum levels of several endocrine disrupters (EDs) (perfluorooctane sulfonate, PFOS; perfluorooctanoic acid, PFOA; di-2-ethylhexyl-phthalate, DEHP; mono-(2-ethylhexyl)-phthalate, MEHP; bisphenol A, BPA) were evaluated concurrently with nuclear receptors (NRs) gene expre...

Article history: Received 10 February 2016 Received in revised form 8 April 2016 Accepted 11 April 2016 Available online xxxx Evidence suggests that women become more intrasexually competitive in the fertile window of the menstrual cycle. Studies using the ultimatum game have extended this to economic decisions, finding that women in the fertile window are less generous towards and more likely ...

Women giving birth at advanced reproductive ages in natural fertility conditions have been shown to have superior postmenopausal longevity. It is unknown whether improved survival is more likely among relatives of late-fertile women. This study compares survival past age 50 of men with and without a late-fertile sister in two populations: Utahns born in 1800-1869 identified from the Utah Popula...

background & aim: assessment of quality of life(qol) is one of the most active areas in modern studies. qol is a term to describe individuals' health and affective, social and physical wellbeing and also to demonstrate their ability for accomplishing daily routine tasks. this study aimed to compare qol domains in fertile and infertile women. method & materials: forty-four infertile women referr...

a r t i c l e i n f o The purpose of this study was to test the influence of hormonal contraceptive use on levels of female intrasexual competition. Twenty-eight women completed a scale for intrasexual competition on three occasions: when using hormonal contraceptives and when regularly cycling at a fertile and a non-fertile cycle stage. When using hormonal contraception, pair-bonded, but not s...

Background: Recent attention has focused on the expression of integrin molecules within the endometrium, and their relation to infertility. Objective: The present prospective study was undertaken to determine whether the endometrium of women with unexplained infertility differs in the expression of very late activation antigens (VLA) from the endometrium of normal fertile women. Methods: Thirty...

BACKGROUND Intercourse in mammals is often coordinated with ovulation, for example through fluctuations in libido or by the acceleration of ovulation with intercourse. Such coordination has not been established in humans. We explored this possibility by examining patterns of sexual intercourse in relation to ovulation. METHODS Sixty-eight sexually active North Carolina women with either an in...

BACKGROUND Chlamydial Inclusion membrane proteins (Incs), are involved in biochemical interactions with host cells and infecting Chlamydiae. We have previously reported the role of two Chlamydia trachomatis (CT) Incs, namely IncB and IncC in generating host immunity in CT infected women. Emerging data shows involvement of Inc stimulated CD4 positive T cells in aiding host immunity in infected f...

Objective Background: Failure in the endometrial receptivity may account for a significant number of infertility cases including unexplained infertility in women. Reduction in the endometrial estrogen receptor-alpha (ER-α) expression during window of implantation may be a critical event that coincides with expression of specific genes and providing a receptive endometrium. The aim of present st...

In evolutionary psychology predictions, women’s mate preferences shift between fertile and nonfertile times of the month to reflect ancestral fitness benefits. Our meta-analytic test involving 58 independent reports (13 unpublished, 45 published) was largely nonsupportive. Specifically, fertile women did not especially desire sex in short-term relationships with men purported to be of high gene...
