Past research has suggested that social support can reduce the negative psychological consequences associated with infertility. Online discussion boards (ODBs) appear to be a novel and valuable venue for men with fertility problems to acquire support from similar others. Research has not employed a social support framework to classify the types of support men are offered and receive. Using temp...
OBJECTIVE To determine whether men and women who are occupationally exposed to ionising radiation are at increased risk of primary infertility. METHODS A cross sectional analysis of reproductive outcome was reported in an occupational cohort of nuclear industry workers from the Atomic Energy Authority, Atomic Weapons Establishment, and British Nuclear Fuels in the United Kingdom. Data on empl...
background : approximately 15 percent of all the couples are involuntarily childless in reproductive ages. the ability to reproduce and give birth to a child is an important part of the human beings life; thus, infertility can cause anxiety for the infertile people. therefore, this study aimed to investigate men’s experiences from male infertility. methods : this was a descriptive phenomenologi...
Background Approximately 15% of couples are infertile with the male factor explaining approximately 50% of the cases. One of the main genetic factors playing a role in male infertility is Y chromosomal microdeletions within the proximal long arm of the Y chromosome (Yq11), named the azoospermia factor (AZF) region. Recent studies have shown there is a potential connection between deletions of t...
PURPOSE OF REVIEW We sought to determine whether infertile men can accurately be identified within a large insurance claims database to validate its use for reproductive health research. RECENT FINDINGS Prior literature suggests that men coded for infertility are at higher risk for chronic disease though it was previously unclear if these diagnostic codes correlated with true infertility. We ...
The present study determined an association between idiopathic sperm disorders in a local Pakistani infertile male population and the MTHFR C677T polymorphism. After ruling out non genetic factors, a total of 437 idiopathic infertile men including 57 azoospermic, 66 oligospermic, 44 asthenozoospermic, 29 teratozoospermic, 20 oligoasthenospermic and 221 infertile normospermic men were recruited....
Factors affecting the blood-testis barrier function may be involved in testicular damage and male infertility. Two cytokines play an important role in the barrier regulation, namely transforming growth factor beta 3 (TGF-β3) and tumor necrosis factor (TNF-α). The aim of this study was to investigate the potential association between TGF-β3 (TGFB3) and TNF-α (TNF) gene polymorphisms and male inf...
BACKGROUND Male infertility is responsible for 50% of infertile couples. Thirty percent of male infertility is due to cytogenetic and genetic abnormalities. In Arab and North African populations, several studies have shown the association of these chromosomal abnormalities with male infertility. Our objective is to evaluate the frequency of chromosomal abnormalities and Y chromosome microdeleti...
OBJECTIVE The aim of this study was to determine the effects of infertility on sexual functions and dyadic adjustment in infertile couples that seek infertility treatment. MATERIALS AND METHODS The Beck Depression Inventory (BDI), Golombok-Rust Inventory of Sexual Satisfaction (GRISS), and Dyadic Adjustment Scale (DAS) were administered to the infertility group (n = 220) and control group (n ...
Varicoceles are a major cause of impaired spermatogenesis and the most common correctable cause of male infertility. They are found in approximately 40% of men with primary infertility and 80% of men with secondary infertility, although they also occur in 12% of men with normal semen parameters. The presence of a varicocele does not always affect spermatogenesis, as it has been reported that on...
