 Male infertility refers to the inability of a man to impregnate a fertile female partner. It is a condition that affects a significant number of couples trying to conceive. Infertility can be attributed to various factors, both physiological and lifestyle-related.

Abnormally shaped sperm may not be able to fertilize an egg effectively. Hormonal imbalances: Hormones play a crucial role in sperm production. Imbalances in hormone levels,...

It is a natural response to challenging or threatening situations, and it can be caused by various factors, including work or school-related pressures, relationship difficulties, financial problems, major life changes, or traumatic events.
