Specifically, the quantity and quality of male sperm began to decline gradually after the age of 30, and the decline rate was faster after the age of 50. In addition, the aging of men will increase the risk of chromosomal abnormalities, which will lead to an increase in the probability of birth defects in children.
Therefore, although there is no age limit for women, men's fertility and reproductive health will also be affected by age. Generally speaking, it is a good age for men to give birth before 40 years old, and the risk of giving birth will gradually increase after 40 years old. However, it should be noted that this is only a general suggestion, and the specific situation needs to be considered in combination with personal health status and actual situation.
