The sperm formation cycle includes the entire process from development and then transportation before sperm are formed. Sperm formation during development is done inside the testes, and it takes about 70 days for the testes to develop sperm. At this time, the spermatozoa are not motile and need to be transported to the epididymal duct, where they slowly gain motility during transport, which takes about 15 days before they are mature sperm. The sperm formation cycle is about 3 months, which is about 90 days. Usually, you should develop good living habits, exercise more, enhance the quality of your body and improve the quality of sperm. The diet can be supplemented with more vitamin intake, less spicy and stimulating food, avoid staying up late, avoid smoking and drinking.
