A short luteal phase impacts fertility by not giving the endometrial lining enough time to thicken for proper implantation, according to Resolve. This can result in lack of pregnancy or recurring miscarriages.Continue Reading
Doctors often refer to a short luteal phase as a luteal phase defect, explains Resolve. The luteal phase is the period of time between ovulation and the start of the menstrual cycle. The average luteal phase is 14 days, but some women have a shorter phase, which leads to the defect and lack of membrane lining of the uterus.
Low progesterone typically causes short luteal phases, notes Resolve. Progesterone starts producing during the follicular phase, which occurs during the first part of the menstrual cycle before ovulation. A woman can find out the length of her luteal phase by tracking her cycles, including using home ovulation predictor kits.
Another possible cause for a short luteal phase is the uterus lining's lack of response to the progesterone produced, according to WebMD. There are also some other medical conditions linked to luteal phase defect and the resulting fertility issues, including anorexia, high amounts of exercise and endometriosis. Thyroid disorders, obesity and polycystic ovarian syndrome are also associated with the condition.Learn more about Pregnancy
