Male factor infertility or subfertility is responsible for up to 50% of infertility cases.
A considerable body of recent studies indicates that lifestyle as well as environmental and psychological factors can negatively affect male fertility, more than previously thought. These negative effects have been shown in many cases to be reversible. This review aims to provide a rationale for early clinical attention to these factors and presents a non-exhaustive evidence-based collection of primary relevant conditions and recommendations, specifically with a view to making first line diagnostics and recommendations. The presently available evidence suggests that considering the high cost, success rates, and possible side effects of assisted reproduction techniques (ART), such as in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI), early efforts to improve male fertility appear to be an attainable and worthwhile primary goal. A series of searches was conducted of Medline, Cochrane and related databases from November 14th, 2010 to January 26th, 2012 with the following keywords: male, fertility, infertility, sperm defects, IVF, ICSI, healthy habits, and lifestyle. Subsequent follow-up searches were performed for upcoming links. The total number of studies contemplated were 1265; of these, 296 studies were reviewed with criteria of relevance; the date of study or review; study sample size and study type; and publishing journal impact status. Data were abstracted based upon probable general clinical relevancy and use. Only a selection of the references has been reflected here because of space limitations. The main results obtained were evidence-supported indications as to the other causes of male infertility, their early detection, and treatment.
