If you are a man with mild asthenospermia, you don't have to be a test-tube baby. You can do conservative treatment, usually add more zinc and vitamin E to improve sperm quality, so you can try to get pregnant naturally again.
But if it is a man with moderate or severe asthenospermia, then he must be a test-tube baby. At present, the second-generation IVF technology used in China is mainly suitable for infertile men, such as men with low sperm motility, poor quality, asthenospermia and azoospermia.
