Abstract
Clinical infertility is the inability of a couple to conceive after 12 months of trying. Male factors are estimated to contribute to 30-50% of cases of infertility. Infertility or reduced fertility can result from testicular dysfunction, endocrinopathies, lifestyle factors (such as tobacco and obesity), congenital anatomical factors, gonadotoxic exposures and ageing, among others. The evaluation of male infertility includes detailed history taking, focused physical examination and selective laboratory testing, including semen analysis. Treatments include lifestyle optimization, empirical or targeted medical therapy as well as surgical therapies that lead to measurable improvement in fertility. Although male infertility is recognized as a disease with effects on quality of life for both members of the infertile couple, fewer data exist on specific quantification and impact compared with other health-related conditions.
期刊介绍：
Nature Reviews Disease Primers, a part of the Nature Reviews journal portfolio, features sections on epidemiology, mechanisms, diagnosis, management, and patient quality of life. The editorial team commissions top researchers — comprising basic scientists and clinical researchers — to write the Primers, which are designed for use by early career researchers, medical students and principal investigators. Each Primer concludes with an Outlook section, highlighting future research directions. Covered medical specialties include Cardiology, Dermatology, Ear, Nose and Throat, Emergency Medicine, Endocrinology, Gastroenterology, Genetic Conditions, Gynaecology and Obstetrics, Hepatology, Haematology, Infectious Diseases, Maxillofacial and Oral Medicine, Nephrology, Neurology, Nutrition, Oncology, Ophthalmology, Orthopaedics, Psychiatry, Respiratory Medicine, Rheumatology, Sleep Medicine, and Urology.
