Study: Male Fertility Impacted by Stressful Early Pregnancy

Men whose mothers had gone through severe stress in early pregnancy might experience fertility problems, said a new study published in the medical journal Human Reproduction. Researchers, who examined 2,804 women during various stages of their pregnancies and revisited their sons years later when they reached the age of 20, found that 63 percent of men whose mothers experienced stress had lower testosterone levels and sperm counts.
