The luteal phase is the second phase of the menstrual cycle. It is also known as the secretory phase and occurs after ovulation. This part of the cycle typically lasts about 14 days; it ends at the beginning of menstruation and plays a significant role in fertility. A luteal phase that is too short or too long can indicate a problem and affect a woman's ability to conceive.


1. Follicular or Proliferative Phase

The follicular or proliferative phase is the first phase of the menstrual cycle, preceding ovulation and the luteal phase. It begins on the first day of a woman's menstrual cycle or the day her period starts. During this phase, the follicles mature, preparing for ovulation. This phase is also important as it creates an environment that is friendly to sperm, encouraging fertilization.
