Abstract Although fertility has traditionally been viewed as the responsibility of women, recent studies suggest that reduced sperm function is a major cause recurrent pregnancy loss affects 1 to 2 percent couples. The reproductive and nutritional history King Henry VIII indicates 70 legitimate pregnancies attributed his six wives resulted in miscarriage or stillbirth. By comparison, only 10 re...
BACKGROUND Oxidative stress in reproductive system leads to sperm DNA damage and sperm membrane lipid peroxidation and may play an important role in the pathogenesis of male infertility, especially in idiopathic cases. Antioxidants such as carotenoids function against free radical damages. OBJECTIVE The aim of this study was to determine the levels of lycopene, beta-carotene and retinol in se...
Apolipoprotein B (APOB) plays a key role in lipoprotein metabolism and plasma lipid transport. It has been shown that about two-thirds of male mice heterozygous for ApoB were infertile. Moreover, a 3-codon deletion polymorphism (rs11279109) in the signal peptide region of the APOB gene has been shown to be a risk factor for infertility in Slovenian men, but its association with infertility in I...
The objective of the present study was to assess the ascorbic acid (AA) levels in seminal plasma of the fertile and infertile men and to investigate its relationship with sperm count, motility and normal morphology. Semen samples were provided by fertile [smoker (n = 25), nonsmoker (n = 21)] and infertile men [smoker (n = 23), nonsmoker (n = 32)]. A simplified method of reverse phase high perfo...
The association between polymorphism of androgen receptor gene CAG (AR-CAG) and male infertility in several studies was controversial. Based on studies on association between AR-CAG repeat length and male infertility in recent years, an updated meta-analysis is needed. We aimed to evaluate the association between AR-CAG repeat length and male infertility in advantage of the data in all publishe...
OBJECTIVES (i) To examine the role of apoptosis in the pathogenesis of DNA damage in semen from infertile men. (ii) To assess the effects of smoking on apoptotic markers and seminal parameters among infertile men. (iii) To assess the correlation of apoptosis with conventional semen parameters. MATERIALS AND METHODS The study was carried out on 70 men with idiopathic infertility, divided into ...
Congenital bilateral absence of vas deferens (CBAVD) is the most common CFTR-related disorder (CFTR-RD) that explains about 1-2% of the male infertility cases. Controversial data have been published regarding the involvement of CFTR mutations in infertile men with non-obstructive azoospermia and oligozoospermia. Here, we describe single base extension (SNaPshot) assay for detection of 11 common...
