Why Can’t I Get Pregnant? 20+ Causes & Treatment Options

Millions struggle with infertility, with 12% of reproductive-age individuals facing challenges. Causes include male factors (30-35%), female factors (30%), and combined/unknown causes. This guide explores 20+ reasons, from hormonal imbalances to lifestyle factors, and treatment options like IVF and IUI.


Key Takeaways

Common Male Infertility Causes: Oligospermia, Varicocele, and Hormonal Imbalances

Low sperm count (oligospermia) and poor motility (asthenozoospermia) are leading male infertility issues. Varicocele, hormonal disorders, and infections like chlamydia also contribute. Treatment options include surgery or medication depending on the root cause.

Ovulation disorders (e.g., PCOS), endometriosis (impacting 10% of PID cases), and age-related egg quality decline are major female infertility causes. Women over 35 experience a 50% drop in fertility by age 40, necessitating earlier evaluations.
