Why can some people not have babies?

There are various reasons some people may not be able to have babies, including medical conditions such as polycystic ovary syndrome (PCOS), endometriOSis, or hormonal imbalances that affect fertility. In men, issues like low sperm count or motility can contribute to infertility. Additionally, age, environmental factors, lifestyle choices, and genetic disorders can also play significant roles in an individual's ability to conceive. In some cases, the cause of infertility may remain unexplained despite thorough medical evaluation.
