Understanding Luteal Phase Defect and Your Treatment Options

A luteal phase defect is a fertility condition that affects a woman’s ovulation cycle and can make achieving a healthy pregnancy difficult, if not impossible. Characterized by low progesterone levels, a luteal phase defect inhibits uterine lining growth, which is required for egg implantation and fetal development. Fortunately, luteal phase defect can easily be identified and treated through lifestyle changes or progesterone-support medicines. Our fertility specialists at Fertility Center of San Antonio can oversee your luteal phase defect treatment at our practice, which has been proudly serving the greater San Antonio, TX, area for three decades.

How a Luteal Phase Defect Affects Fertility

The luteal phase is the period of time between ovulation and menstruation. The duration of the luteal phase is typically 12 to 16 days. During this time, progesterone levels increase and the uterine lining thickens to create a healthy environment for potential egg implantation.

 A short luteal phase can directly affect your fertility.

Some women, however, have a shortened luteal phase of 10 days or less. These women will experience lower progesterone levels and thinner uterine lining. As a result, it will be much harder for them to become and stay pregnant.

Signs and Symptoms

Most women with luteal phase defect do not realize they have the condition until they try to conceive and find it challenging. A shortened luteal phase may become apparent after a hopeful mother-to-be begins tracking her ovulation cycles and realizes there are fewer days than there should be between ovulation and menstruation.

Additionally, there are a few common symptoms of luteal phase defect, including:

  • Spotting between periods
  • Early menstrual cycles
  • Difficulty becoming pregnant
  • Miscarriage

Causes of a Short Luteal Phase

Any woman can develop a short luteal phase when her body does not produce enough progesterone. Certain health conditions can put a woman a higher risk for a short luteal phase, including:

If you have had unsuccessful attempts at conception, or unexplained losses, a luteal defect may be a factor.

Diagnosing Issues with Your Cycle

If you are having difficulty conceiving or maintaining a healthy pregnancy, your doctor can run blood tests to check the following hormone levels:

  • Follicle-Stimulating Hormone (FSH) - the hormone that stimulates ovarian follicle growth.
  • Luteinizing Hormone (LH) - the hormone that triggers ovulation
  • Progesterone - the hormone that causes uterine lining growth and supports a healthy pregnancy.

In some instances, an endometrial biopsy can be performed a day or two before your expected menstrual cycle. A sample of your uterine lining is collected and examined under a microscope to evaluate its thickness.

Personalized Treatment Options

In some cases, treatment for a luteal phase defect involves simple changes to your daily life. For example, women facing considerable stress may be encouraged to practice stress management techniques, such as meditation or moderate exercise.

Additionally, there are supplements and medications that can normalize the length of a woman’s luteal phase, such as:

  • Progesterone - Since low progesterone levels and luteal phase defect are correlated, it probably comes as no surprise that progesterone supplements can overcome luteal phase defect. Women will typically take this supplement following ovulation until the end of their cycle.
  • Human Chorionic Gonadotropin (HCG) - Also known as the pregnancy hormone, this supplement encourages progesterone secretion.
  • Clomiphene Citrate - This medication stimulates ovulation by encouraging the release of FSH and LH.
