Infertility is defined as the failure to achieve a clinical pregnancy after 12 months of regular unprotected intercourse. It affects approximately 9-15% of reproductive-aged couples worldwide. The main causes of infertility include female factors like PCOS, endometriosis, and tubal damage; male factors like low sperm count or quality; and unexplained infertility. Treatments for infertility include ovulation induction, intrauterine insemination, in vitro fertilization, and others. Religious views on assisted reproduction vary between religions, with some being more accepting than others.
