In the case of infertility, the culprit is usually biological in nature, and can come about essentially because of old age. Particularly, as man goes beyond his prime years, the male sexual hormone testosterone is produced at significantly lower amounts, drastically affecting his desire for sexual intimacy. In contrast, the stress hormone, cortisol, is produced at comparatively higher amounts, perhaps due to family-related problems and even to post-work concerns.
