What needs to occur for a successful pregnancy to transpire, without the intervention of fertility treatments?

1. Ovulation: Production and release of an ovum (egg) into the fallopian tube accomplished by the female reproductive system at a specific time of her menstrual cycle.

2. Sexual intercourse: An interaction between the male and female reproductive organs: penis and vagina, respectively.

3. Sperm deposit and journey: Through ejaculation from the penis, semen contaning sperm cells are deposited in the vaginal canal via sexual intercourse. Healthy sperm must travel the equivalent of a marathon (42 KM, or 26.2 miles) in search of the egg located within a fallopian tube of the female reproductive system.

4.Fertilization: A single sperm cell must then penetrate the egg cell located within the fallopian tube, forming a pre-embryo.

5.Pre-embryo journey: A 5-6 day journey is completed by the pre-embryo to reach its final destination, the wall of the uterus (or the endometrium) in the female reproductive system.

6. Implantation: Once the pre-embryo reaches the uterus, it must implant on the endometrium to begin fetal development and pregnancy ensues for the following 9 months.
