A member asked:

How long can a luteal phase be in a 28 day cycle?

A doctor has provided 1 answer

Can vary some.: Normal is 14 days, but in various ovulation disorders the luteal phase may be shortened. In advanced reproductive age, >35, the luteal phase might shorten some as well. The most variability though is in the follicular phase with age. Cycles closer than 27 days indicate ovarian aging. Good luck.
