Infertility remains a significant problem for many couples. Approximately one in seven couples who attempt to conceive will fail to do so within 1 year. In about 65% of these cases, there is a male component of infertility.1 Despite normal semen parameters, the etiology of infertility remains uncertain in more than 50% of couples.2 Defects in sperm proteins and/ or structures may underlie certa...

BACKGROUND As more women choose to delay childbearing, increasing numbers of them face age-related fertility problems. We aimed to explore the association between age and diagnosed causes of female infertility. METHODS Anonymized data (age of male and female partner, year of first visit, diagnosis, duration and type of infertility) were obtained on all couples attending Aberdeen Fertility Cen...

BACKGROUND The aim of the present study was to investigate the psychological influence of gender infertility diagnoses among men in couples about to start their first IVF or ICSI treatment. METHODS The study was a part of a prospective study of 65 men with male infertility diagnosis and 101 men in couples with female, mixed and unexplained infertility diagnoses. Of the 200 men invited, 166 ag...

Background: Aim of the study was to evaluate correlation endometrial morphology and sub vascularity with pregnancy rate in fresh frozen embryo transfer cycles.Methods: Prospective, non-randomized observational done on 76 women undergoing vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) treatment at a tertiary health care center. Woman tubal factor, male factor unexplained inferti...

For many years, the management of male-factor infertility has been empirical rather than evidence-based. In current clinical practice, assisted reproductive techniques are the most successful methods of alleviating male-factor infertility. To date, it remains unclear what adjuvant actions can be taken to improve the outcome of assisted reproductive techniques for male-factor infertility. Eviden...

BACKGROUND Intracytoplasmic sperm injection (ICSI) is the primary treatment for male infertility. However for this procedure, with the exception of visual morphological selection, there is no standardization for sperm selection. Recently, the hypo-osmotic swelling test (HOST) has been proposed to potentially select sperm with intact membranes. The aim of this study is to evaluate the ability of...

OBJECTIVE We aimed to evaluate the association between infertility etiology in ICSI pregnancies and preeclampsia; besides, we aimed to discuss the effect of the paternal factor in the pathogenesis of preeclampsia. HYPOTHESIS We hypothesized that preeclampsia is more common in ICSI pregnancies with male factor. It is known that maternal exposure to paternal sperm cells over a time period has a...

In male mice heterozygous for a null apolipoprotein B (apoB), allele infertility was noticed. These data led us to investigate a possible role of APOB gene polymorphism and male infertility in humans. In this case-control study, we searched for an association between the insertion/deletion (I/D) polymorphism of the APOB gene and male infertility in 560 Slovene Caucasian men. The study group con...

To investigate a possible common environmental exposure that may partially explain the observed decrease in human semen quality, we correlated seminal plasma and blood cadmium levels with sperm concentration and sperm motility. We studied three separate human populations: [Group 1] infertility patients (Long Island, NY), [Group 2] artificial insemination (AI) donors (Rochester, NY), and [Group ...

Oxidative stress and reactive oxygen species (ROS) are generated from both endogenous and environmental resources, which in turn may cause defective spermatogenesis and male infertility. Antioxidant genes, which include catalase (CAT), glutathione peroxidase (GPX), glutathione S-transferase (GST), nitric oxide synthase (NOS), nuclear factor erythroid 2-related factor 2 (NRF2), and superoxide di...
