Infertility can result from factors affecting either partner or, in some cases, both. Common causes in women include ovulation disorders such as PCOS, endometriosis, blocked fallopian tubes, hormonal imbalances, and age-related decline in egg quality. In men, reduced sperm count, poor motility, abnormal sperm morphology, varicocele, hormonal disorders, or certain lifestyle factors may contribute. Sometimes, despite thorough evaluation, no specific cause is identified. At Horizon Women & Fertility, we perform a comprehensive assessment of both partners to identify the underlying cause and recommend the most appropriate treatment plan.
