Did you know? Infertility affects about 3.9% to 16.8% of couples in India today. Sounds surprising, doesn’t it? Several factors contribute to this growing number; however, wrong ovulation timing remains a significant reason. Ovulation occurs only once during every menstrual cycle, and many couples miss the fertile window each month. The fertile phase lasts for only a short time, and missing it sharply reduces the chances of pregnancy.

However, some blood tests measure key fertility hormones to help you accurately identify this window. These hormones include luteinizing hormone (LH) and progesterone. Together, both tests provide strong insights into cycle health.

Let’s explore the optimal timing for LH and progesterone tests so you can test wisely and make confident fertility decisions.
