Menstrual cycle
Some sources define the end of the luteal phase to be a distinct "ischemic phase".[2]
Luteal phase defect
Luteal phase defect (LPD) is believed to interfere with the implantation of embryos[3] The lactational amenorrhea method of birth control works primarily by preventing ovulation, but is also known to cause LPD.References

The follicular phase (or proliferative phase) is the phase of the estrous cycle, (or, in humans and great apes, the menstrual cycle) during which follicles in the ovary mature. It ends with ovulation. The main hormone controlling this stage is estradiol.

Gametogenesis is a process by which the diploid germ cells undergo a number of chromosomal and morphological changes to form mature haploid gametes. Depending on the biological life cycle of the organism, gametogenesis occurs by meiotic division of gametocytes into various gametes

Fertilization (also known as conception, fecundation and syngamy), is fusion of gametes to form a new organism of the same species. In animals, the process involves a sperm fusing with an ovum, which eventually leads to the development of an embryo.
