What Is the Luteal Phase?

The luteal phase is a familiar concept to many women; however, some women are uncertain about when it occurs. So, what exactly is the luteal phase?

What Is the Luteal Phase?

The luteal phase refers to the period beginning the day after ovulation and ending the day before menstruation starts. Its duration is relatively consistent—averaging 14 days in non-pregnant women—and concludes on the first day of menstrual bleeding. Following ovulation, under the influence of luteinizing hormone (LH), ovarian cells undergo further division, accumulating yellowish pigment granules and developing a characteristic texture that appears orange to the naked eye. This newly formed endocrine structure is termed the corpus luteum. Thus, the luteal phase generally spans from the day after ovulation until the day before the onset of menstruation, typically lasting 14 days. For example, in a 28-day menstrual cycle, the luteal phase corresponds to days 15–28.

During the luteal phase up to the onset of menstruation, avoid consuming cold, raw, or highly stimulating foods. Additionally, refrain from vigorous physical activity during the ovulatory phase, as this may lead to corpus luteum rupture and associated hemorrhage. Maintain good hygiene of the genital area as well.

In daily life, increase intake of fresh fruits and vegetables, eliminate unhealthy habits, avoid chronic sleep deprivation, and cultivate a regular sleep schedule—going to bed early and rising early. If menstrual irregularities occur, consult a healthcare provider for endocrine testing and receive targeted treatment accordingly. We hope this information proves helpful to you.
