Luteal phase The luteal phase is the latter phase of the menstrual cycle (in humans and a few other animals) or the earlier phase of the estrous cycle (in other placental mammals). It begins with the formation of the corpus luteum and ends in either pregnancy or luteolysis. The main hormone associated with this stage is progesterone, which is significantly higher during the luteal phase than other phases of the cycle. The opposite of the luteal phase, the rest of the two weeks, is called the follicular phase. After ovulation, the anterior pituitary hormones FSH and LH cause the remaining parts of the dominant follicle to transform into the corpus luteum.

This allows the baby to move into the birth canal. The first stage is the longest of the three stages. It's actually divided into two phases of its own — early labor (latent phase) and active labor.

During this time, the mare will have an estrous cycle of 21 days (±3 days). The estrous cycle is composed of two phases: the estrous phase (in heat) and the diestrous phase (out of heat).Estrus usually lasts for 6 days, but can be 4-10 days, depending on the mare.Diestrus is normally 15 days, but may vary from 12-18 days.he estrous cycle is composed of two phases: the estrous phase (in heat) and the diestrous phase (out of heat).

Luteal Phase Defect The luteal phase is one stage of your menstrual cycle. It occurs after ovulation (when your ovaries release an egg) and before your period starts. During this time, the lining of your uterus normally gets thicker to prepare for a possible pregnancy. If you have a luteal phase defect, that lining doesn't grow properly each month. This can make it difficult to become or remain pregnant.
