Asthenozoospermia is a medical condition characterized by reduced sperm motility, meaning that sperm have difficulty moving effectively. This can impact fertility, as motile sperm are essential for reaching and fertilizing an egg. The condition can be diagnosed through a semen analysis, which evaluates the movement and quality of sperm. Several factors can contribute to asthenozoospermia, including lifestyle choices, environmental exposures, and underlying health issues. Treatments may involve lifestyle changes, medications, or assisted reproductive technologies like in vitro fertilization (IVF) to help couples achieve pregnancy despite this condition.
