Genetic alteration linked with human male infertility
One in seven couples worldwide has difficulty conceiving a child, and male infertility is thought to account for nearly half of those cases. Although the cause of male infertility is often unknown, scientists have now discovered a genetic alteration that disrupts sperm production in otherwise healthy men. The research, published by Cell Press on Sept. 30 in the American Journal of Human Genetics, provides new insight into one cause of male infertility. (2010-09-30)

Use of IVF procedure for male infertility has doubled; not linked with improved outcomes
The use of an assisted reproduction technique known as intracytoplasmic sperm injection doubled between 1996 and 2012, although compared with conventional in vitro fertilization, use of intracytoplasmic sperm injection was not associated with improved reproductive outcomes, according to a study in the Jan. 20 issue of JAMA. (2015-01-20)

IVF is more cost-effective than intra-uterine insemination, mathematical model predicts
A theoretical study reveals that in-vitro fertilisation is less costly and more cost-effective than intra-uterine insemination, for the treatment of infertility in couples with unexplained infertility or mild male factor subfertility. In a study published today in the open access journal BMC Health Services Research, researchers use a mathematical model to show that offering a full cycle of in-vitro fertilisation (IVF) is better value for money for couples and tax-payers. (2006-06-22)

Male infertility: Urogenital infection as a possible cause
In couples who have not been able to have children, male infertility is the cause in at least half of cases. In 6-10% the cause is a urogenital infection. The risk of irreversible infertility associated with urogenital infections in men should not be underestimated, say Hans-Christian Schuppe and coauthors in a review article in the current issue of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2017; 114: 321-7). (2017-06-14)

The nation's most in-depth study of the quality of sperm shows that sperm counts previously thought to be abnormal do not always mean infertility, and that the shape and ability of sperm to move are important measures. The authors say the findings demonstrate in scientific terms what many clinicians already suspect: that male infertility is not as clear-cut as the current laboratory guidelines suggest. (2001-11-07)

Is there a link between infertility and child educational outcomes?
Findings from study co-authored by a University of Illinois at Chicago sociologist suggest that involuntary childlessness prior to either a first or a second birth is associated with lower academic achievement -- both test scores and grade point average -- at age 16, even if the period of infertility was prior to a sibling's birth rather than the child's own. (2017-06-05)
