Semen quality refers to the characteristics of a man's sperm, which are crucial for fertility. Key factors include sperm count, motility (the ability to move), morphology (shape), and overall volume. High-quality semen increases the chances of successful conception. Several factors can influence semen quality, such as age, lifestyle choices, and environmental exposures. For instance, smoking, alcohol consumption, and obesity can negatively impact sperm health. Regular check-ups and a healthy lifestyle can help maintain or improve semen quality, which is important for couples trying to conceive.
