BACKGROUND Thrombophilia-related mutations, such as coagulation factor V Leiden and factor II (G20210A), have been associated with female infertility due to spontaneous abortions during pregnancy. The possible role of mutations of these two factors in male infertility has not been studied to date. MATERIALS AND METHODS A total of 208 unrelated Greek men were investigated, including 108 infert...

The world's population is increasing at an alarming rate and is projected to reach nine billion by 2050. Despite this, 15% of couples world-wide remain childless because of infertility. Few genetic causes of infertility have been identified in humans; nevertheless, genetic aetiologies are thought to underlie many cases of idiopathic infertility. Mouse models with reproductive defects as a major...

Oxidative stress contributes to defective spermatogenesis and the poor quality of sperm associated with idiopathic male factor infertility. The aim of this study was to review the current literature on the effects of various types of antioxidant supplements in patients to improve fertilization and pregnancy rates in subfertile males with idiopathic oligoasthenoteratozoospermia (iOAT). Review of...

Infertility is a common condition caused by the female factor, male or both. problems can have significant impact on married couples who experience them. In addition to causing medical problems, infertility also cause economic and psychological problems. Couples will undergo long process of evaluation treatment, where this be both physical for infertile couple. The aim article presenting litera...

infertility can be caused by an unexplained reduction in semen quality in males who present asnormal on physical examination and endocrine testing. there is some evidence that aberrantmetabolism of micronutrients such as choline may play a causative role in male factorinfertility. choline is a crucial factor in the regulation of sperm membrane structure andmotility, and this nutrient plays an i...

We evaluate the association between genetic polymorphisms of XRCC5 VNTR, XRCC6 -61C>G, and XRCC7 6721G>T with male infertility susceptibility. A total of 392 men including 178 infertile males (102 idiopathic azoospermia and 76 severe oligozoospermia) and 214 healthy controls were recruited. XRCC6 -61C>G and XRCC7 6721G>T genotyping was performed by PCR-RFLP whereas XRCC5 VNTR was performed by P...

First published October 21, 2014; doi:10.1152/ajpendo.00416.2014.—About 15% of heterosexual couples in the USA suffer from infertility issues; male infertility accounts for 50% of all infertility cases and roughly 50% of male...

The TP53, a transcriptional regulator and tumor suppressor, is functionally important in spermatogenesis. MDM2 is a key regulator of the p53 pathway and modulates p53 activity. Both proteins have been functionally linked to germ cell apoptosis, which may affect human infertility, but very little is known on how common polymorphisms in these genes may influence germ cell apoptosis and the risk o...

INTRODUCTION Male factor infertility contributes partially and solely to the problem of childlessness in around 50% of the cases. Unfortunately, 30 - 50% of the etiologies of male infertility are unknown and therefore, no specific therapy can be instituted. Evidence-based medical therapy for male infertility is an attractive research area where a large number of clinical trials, controlled and ...

About 15% of heterosexual couples in the USA suffer from infertility issues; male infertility accounts for ∼50% of all infertility cases and roughly 50% of male infertility is idiopathic. Increased levels of plasma cholesterol affect spermatogenesis and male fertility negatively, but by unclear mechanisms. Clearly, spermatogenesis occurs in immune-privileged seminiferous tubules that are protec...
