Managing Shortened Luteal Phase for Conception

Luteal Phase

You and Your Luteal Phase

Guest post by Kate Davies

Many of my fertility patients come to me with concerns about their menstrual cycle and whether it is normal. The most frequent problem I see is with the luteal phase of the cycle.

The luteal phase (LP) is the post ovulatory phase of your cycle which lasts until menstruation. This is when fertilization and implantation occur. It is essential that the length and quality of the LP is sufficient enough to support an implanting pregnancy, ideally being 10 days or longer in length. In general, a normal LP is between 10-16 days. A short LP can cause complications in trying to conceive, and women who regularly have a short LP may suffer from Luteal Phase Defect (LPD).

Symptoms of LPD can be:

  • A short menstrual cycle
  • Low progesterone levels
  • A disruption in Basal Body Temperature (BBT) readings post ovulation

If you are concerned that your LP is short or think you may have LPD, you should discuss this with your doctor. It is important to mention that although the diagnosis of LPD has been described convincingly in the research setting, it remains a controversial clinical entity (Bukulmez and Arici 2004, Shivapathasundram et al. 2010). As a result of the uncertainties that surround the diagnosis of LPD, medical treatment is controversial and may not be offered by your doctor.

What Causes Shortened LP?

Low progesterone levels is a common cause of a shortened LP. Good progesterone levels are crucial to support an implanting pregnancy, and low levels can be the cause of infertility or recurrent early miscarriage. It is therefore important to consult your doctor if you suspect that this may be causing you a problem, as there may be other causes for progesterone deficiency such as thyroid disorders or Polycystic Ovarian Syndrome (PCOS).

Symptoms can include:

  • breast tenderness
  • loss of libido
  • headaches that are associated with your menstrual cycle
  • acne
  • anxiety
  • irritability
  • insomnia
  • weight gain
  • PMS
  • irregular bleeding

What can you do to improve your cycle, progesterone levels and LP naturally?


  • I recommend that you start fertility charting to assess your hormonal health and look closely at your LP. Find out exactly how long your LP is and how often it is less than 10 days. Observe your temperature for an indication on how healthy your progesterone levels are. Your temperature is a direct indication as to what is happening with your progesterone levels. For example, after ovulation your temperature should stay raised and above the pre-ovulatory temperatures. In general, your temperature will stay raised through the LP, dropping only the day before or the day that your next bleed starts. If your temperature drops early, this can indicate low progesterone levels.


  • Ensure an adequate supply of Vitamin C in your diet – Research shows vitamin C improves hormone levels and increases fertility in some women with LPD. Foods rich in vitamin C include: papaya, bell peppers, broccoli, sprouts, strawberry and oranges.
  • Essential fatty acids – these are vital for balanced hormone production. Many women are low in omega 3. Foods rich in essential fatty acids are walnuts, salmon, sardines and scallops.
  • Green leafy vegetablesGreen vegetables are rich in vitamin B complex and are necessary for good hormonal balance.



  • Consider taking magnesium, vitamin E and evening primrose supplements.
  • For PCOS Inositol supplementation will help regulate a menstrual cycle.


  • Vitex (Chasteberry)

Research has shown this herb to effectively lengthen the LP. It helps the body to increase its own production of luteinizing hormone (promoting ovulation) boosting progesterone levels during the LP of the cycle. Consult a qualified herbalist if you are considering this treatment.


  •   Women with LPD have significantly lower levels of antioxidants. Make antioxidants part of your every day foods by enjoying blackberries, blueberries, garlic, kale, strawberries, sprouts, plums, broccoli and red peppers.

Alternative therapy

  •    Acupuncture– Randomized controlled trials in China have demonstrated benefits to the menstrual cycle and fertility (Song 2008), however caution is needed when interpreting these studies as they may not be of high quality. In the West, there is a paucity of evidence for the benefits of acupuncture on the menstrual cycle and fertility (Balen et al. 2016) and it is clear that further research is needed. However, a recent study by Stener-Victorin et al. (2016) identified a decrease in circulating androgens in women with PCOS which in turn would improve cycle regularity and the luteal phase. If you are considering acupuncture to help with cycle regulation and your luteal phase, find an acupuncturist who specializes in fertility.
