The effects of advanced paternal age on fertility

引用

Asian Journal of Andrology 2013年第6期15卷 723-728,I0005页

作者： Jason r Kovac Josephine Addai ryan P Smith robert M coward Dolores J Lamb Larry I Lipshultz Scott Department of Urology Department of Molecular and Cellular Biology The Center for Reproductive Medicine Baylor College of Medicine Houston TX 77030 USA

Modern societal pressures and expectations over the past several decades have resulted in the tendency for couples to delay conception. While women experience a notable decrease in oocyte production in their late thirties, the effect of age on spermatogenesis is less well described. While there are no known limits to the age at which men can father children, the effects of advanced paternal age are incompletely understood. This review summarizes the current state of knowledge regarding advanced paternal age and its implications on semen quality, reproductive success and offspring health. This review will serve as a guide to physicians in counseling men about the decision to delay paternity and the risks involved with conception later in life.
