Subfertility is a condition in which a couple has difficulty conceiving a pregnancy after trying for an extended period of time.

It is a common issue affecting many couples, and can be caused by a range of factors, including hormonal imbalances, structural problems in the reproductive system, and lifestyle factors such as age, obesity, and smoking.

Symptoms of subfertility can include irregular menstrual cycles, a history of infertility in the family, and the presence of certain medical conditions such as polycystic ovary syndrome (PCOS) or endometriosis.
