AIM To study the transcriptome profiles in the blood of recurrent implantation failure (RIF), recurrent miscarriage (RM) and fertile women during the window of implantation, and further analysis the correlation of transcriptome profiles between blood and endometrium. METHODS This is an observational prospective study. In total 9 subjects were recruited, 3 RIF, 3 RM, and 3 controls. Paired sam...

Natural human embryonic mortality is generally considered to be high. Values of 70% and higher are widely cited. However, it is difficult to determine accurately owing to an absence of direct data quantifying embryo loss between fertilisation and implantation. The best available data for quantifying pregnancy loss come from three published prospective studies (Wilcox, Zinaman and Wang) with dai...

This study was undertaken to establish whether ovulation in humans alternates consistently from right to left ovary in successive cycles and whether the site of ovulation affects the next cycle length or the hormonal profiles. A total of 199 cycles in 80 normally fertile women were studied. The volunteers were monitored with ultrasonography to determine the day and side of ovulation and to calc...

The purpose was to study the prevalence of environmental intolerance (EI) and its different manifestations, including behavioral changes and disability. Fertile-aged women (n = 680) of the Kuopio Birth Cohort Study were asked about annoyance to 12 environmental factors, symptoms and behavioral changes. We asked how much the intolerance had disrupted their work, household responsibilities or soc...

Olfaction is an important determinant of attractiveness, possibly even more so than vision when judgments are made by women. However, research that directly compares these cues using actual stimuli (e.g., t-shirt odors) is lacking. In this study, 44 women rated the attractiveness of t-shirt odors and facial photographs of 21 men either independently (i.e., first rated t-shirts, then rated photo...

BACKGROUND Infertility is a major life crisis which can lead to the development of psychiatric symptoms and negative effects on the quality of life of affected couples, but the magnitude of the effects may vary depending on cultural expectations. AIM We compare the level of psychiatric symptoms, disability, and quality of life in fertile and infertile women in urban Turkey. METHODS This cro...

background: infertility is a factor which has been linked to higher prevalence of sexual dysfunctions in women; however, ambiguous results have been reported about the impact of infertility on women’s sexual satisfaction. the purpose of this study was to compare sexual and dyadic functioning in infertile and fertile women. furthermore, the associations between sexual variables and clinical vari...

Endometrial polyps are a frequent finding in infertile patients. Little is known about the true prevalence of polyps in infertile patients. It is unproved whether polyps are causative of infertility, or whether surgical polypectomy by hysteroscopy improves the likelihood of successful conception. This article reviews endometrial polyps in reproductive-age fertile and infertile women.

BACKGROUND Thiols are scavengers of reactive oxygen species (ROS). We aim to investigate associations between thiols in various fluids in (sub)fertile couples and fertility outcome parameters. METHODS In 156 couples undergoing assisted reproduction techniques (ART), we measured the concentrations of glutathione (GSH), cysteine (Cys), homocysteine (Hcy) and cysteinylglycine (CGS) and fertility...
