Why would unbalanced hormone levels make it hard to become pregnant?

Unbalanced hormone levels can disrupt the menstrual cycle and ovulation, making it difficult for the body to release an egg for fertilization. Hormones like estrogen and progesterone play critical roles in preparing the uterine lining for implantation; if these are out of balance, the environment may not be suitable for a fertilized egg to implant. Additionally, conditions like polycystic ovary syndrome (PCOS) and thyroid disorders, which are often linked to hormonal imbalances, can further hinder fertility. Overall, maintaining balanced hormone levels is essential for successful conception.
