Introduction

Ovulation is a key part of female fertility, and understanding it is important whether you’re trying to conceive, donate eggs, or become a surrogate. In this blog, we break down what ovulation is, when it occurs, and how to identify it in your cycle.

What Is Ovulation?

Ovulation is the release of a mature egg from the ovary. It typically happens once per menstrual cycle and is the time when you’re most fertile. Once released, the egg travels down the fallopian tube and is available for fertilization for about 12–24 hours.

When Does Ovulation Occur?

Ovulation usually occurs **around day 14 of a 28-day cycle**, but this can vary based on your individual cycle length. In general, it occurs **14 days before your next period**, not necessarily 14 days after your last one.

How to Track Ovulation

• Ovulation Predictor Kits (OPKs): Detect hormone surges in urine
• Basal Body Temperature (BBT): Slight increase after ovulation
• Cervical Mucus: Becomes clear and stretchy, like egg whites
• Ultrasound: Used in fertility treatments to measure follicle size

Why Ovulation Matters for Fertility

Timing intercourse, insemination, or embryo transfer around ovulation significantly increases chances of pregnancy. For egg donors and surrogates, knowing your cycle helps schedule medication and procedures accurately.

Ovulation in Egg Donation and Surrogacy

• Egg Donors: Must ovulate regularly unless the cycle is controlled with stimulation meds
• Surrogates: Ovulation is usually suppressed with medication to prepare for embryo transfer

Irregular Ovulation or Anovulation

Some women don’t ovulate regularly, which can affect fertility. Conditions like PCOS, thyroid disorders, or low body weight can interfere with ovulation. A fertility specialist can evaluate and help regulate your cycle.
