Editing Ovulation (section)

=== Luteal phase ===
{{Main|Luteal phase}}

The follicle proper has met  the end of its lifespan. Without the oocyte, the follicle folds inward on  itself, transforming into the [[corpus luteum]] (pl. corpora lutea), a  steroidogenic cluster of cells that produces [[estrogen]] and [[progesterone]]. These hormones induce the  endometrial glands to begin production of the [[endometrium|proliferative endometrium]] and later  into [[endometrium|secretory endometrium]], the site of embryonic growth if implantation occurs. The action of progesterone increases [[basal body temperature]] by one-quarter to one-half degree Celsius (one-half to one degree Fahrenheit).  The corpus luteum continues this [[paracrine]]  action for the remainder of the menstrual cycle, maintaining the endometrium, before disintegrating into scar tissue during menses.<ref>{{cite news|title=Usually, it occurs between the 10th and 20th day of your menstrual cycle|url=http://www.momjunction.com/ovulation-calculator/|access-date=26 July 2016|work=momjunction}}</ref>
