Infertility is a condition that affects a person's ability to conceive a child. It can occur in both men and women and is often defined as not being able to get pregnant after trying for a year or more. Various factors can contribute to infertility, including age, hormonal imbalances, and medical conditions like polycystic ovary syndrome or low sperm count. Many couples facing infertility may seek help from a fertility specialist. Treatments can range from lifestyle changes and medication to assisted reproductive technologies like in vitro fertilization (IVF). Understanding infertility is essential for those trying to start a family, as it can help them explore their options and find support.
