Nutrition and fertility: male aspects

Abstract

Infertility affects about 15% of couples seeking to
obtain a pregnancy. In 20 to 50% of the cases, a
deficiency in sperm quality or a male factor is
observed. Many factors, related to lifestyle and
environment, are likely to influence male fertility
by leading to deleterious quantitative or qualitative
effects on sperm.
Among those factors, a recent and growing interest
is put on overweight, combined or not with metabolic or nutritional disorders of male partners of
infertile couples. We here reviewed the relationships between weight and nutriments and male
infertility.
