Which Hormone Control Luteal Phase?

The next phase of the menstrual cycle is the luteal or secretory phase. This phase always occurs from day 14 to day 28 of the cycle. Progesterone stimulated by LH is the dominant hormone during this phase to prepare the corpus luteum and the endometrium for possible fertilized ovum implantation.

What hormone is responsible for luteal phase?

The Luteal Phase

During this period, changes occur which will support the fertilized egg (embryo) should pregnancy result. The hormone responsible for these changes is progesterone and it is manufactured by the corpus luteum.

What stimulates the luteal phase?

Progesterone induces a secretory transformation of the endometrium in the luteal phase (Bourgain et al.,1990). By inducing this change after adequate estrogen priming, progesterone improves endometrial receptivity (Kolibianakis and Devroey, 2002).
