BACKGROUND Previous research has suggested an interaction between distress and male fertility. The present longitudinal study sought to deliver evidence for a negative impact of distress due to infertility on sperm concentration. METHODS The sample consisted of 120 patients who twice visited an andrological clinic on their own initiative for fertility work-ups. Baseline and follow-up examinat...

BACKGROUND Infertility is one of the most significant medical, as well as social problems that affect psychological health of families and societies. Determining the prevalence of infertility is important for evaluating the potential of fertility. There are different reports on the prevalence of infertility in Iran, but the current research employs fertility history in order to provide an unbia...

Because research on infertile women usually uses clinic-based samples of treatment seekers, it is difficult to sort out to what extent distress is the result of the condition of infertility itself and to what extent it is a consequence of the experience of infertility treatment. We use the National Survey of Fertility Barriers, a two-wave national probability sample of U.S. women, to disentangl...

An assumption in case-control studies is that forces of selection are the same for cases and controls. This may not be true for studies of male infertility among infertility clients. Earlier reproductive outcomes may introduce modification of risk behavior or differential referral. Selection bias might also occur when infertile males are compared with fertile males. Partners of sterile men are ...

BACKGROUND The relationship between intramural myomas and fertility remains unclear. The main debate rests on whether cavity-distorting intramural myomas (CDMs) adversely affect fertility more than non-CDMs. We aimed to compare the effects of enucleating non-CDMs and CDMs on fertility improvement in females with unexplained infertility. METHODS We prospectively recruited 83 women undergoing m...

Infertility is a worldwide reproductive health and emotionally charged problem that affects approximately 15% of married couples. In recent years, male infertility has increased in the industrialized countries due to a decline in sperm counts and a rise in testicular and sperm pathologies. There seems to be a direct relationship between modern lifestyles and declining male fertility and the sta...

Infertility is a growing medical and social problem in the world; and approximately one of five couples has problems with conception [1]. Several fertility workers did focus in their search on female etiological factors for infertility, despite the fact that assessment of male fertility potential is of great importance. Male partner may involve in the aetiology of half of cases, either as prima...
