A few studies have found poor semen quality in sons whose mothers have received fertility treatment, but it is unknown whether the poor semen quality is related to the infertility treatment or to infertility per se, for example, whether it is caused by hereditable factors. Using data from a population-based, Danish follow-up study conducted in 2005–2006, the authors of the present study examine...

OBJECTIVE Low grade systemic inflammation (LGSI) as well as androgen deficiency has in older men been associated with several pathologies, including cardiovascular disease (CVD). We wanted to investigate whether low testosterone levels are linked to biomarkers of LGSI already in young age, before any concurrent manifestations of CVD or other systemic diseases. DESIGN Nested cross-sectional st...

BACKGROUND Zinc in human seminal plasma is divided into three types of ligands which are high (HMW), intermediate (IMW), and low molecular weight ligands (LMW). The present study was aimed to study the effect of Zn supplementation on the quantitative and qualitative characteristics of semen along with Zinc Binding Protein levels in the seminal plasma in asthenozoospermic patients. METHODS Sem...

Specific binding of oxytocin to high affinity sites in endometrial membrane preparations has previously been shown in sheep. Endometrial tissue preparations from 27 'normal' women of proven fertility were incubated with tritiated oxytocin and the existence of significant binding sites in human endometrium was shown. Furthermore, the level of binding sites underwent a cyclical variation with the...

BACKGROUND Chlamydia trachomatis is more prevalent in subfertile women than in the general population and is the leading cause of tubal factor subfertility. As C. trachomatis infections are sexually transmitted, it can be expected that infections with human papillomavirus (HPV) are also more prevalent in this group of women. HPV is a necessary cause for the development of cervical (pre-)maligna...

The choice of adoption over genetic parenthood was investigated in 105 women retrospectively by questionnaire. Participants were divided into four groups: female/male subfertility; female subfertility; male subfertility; and female/male fertility. Half the sample (59/105) answered the question about the importance of a genetic link. Women who failed to adopt thought a genetic link was important...

sperm selection techniques have became an important tool to improve sub fertile ejaculates. the main aim of this study was to assess the dynamics of motile sperm subpopulations of ejaculates from subfertile stallions subjected to density gradient centrifugation (dgc) involving a double layer colloid [dgc2], before and after storage for 24 and 48 hours. ejaculates from eight stallions with ferti...

Y chromosome deletions in the three azoospermia factor (AZF) regions constitute the most common genetic cause of spermatogenic failure. The aim of this study was to estimate the length and boundaries of the AZF deletions and to correlate the AZF deletions with the sperm concentrations, testicular histology, Y haplogroups and the ethnic origin of the men with deletions. PCR analysis of STS loci ...
