00:00During ejaculation, approximately 300 million sperm travel from the testes through the vas deferens into the prostate.
00:09The prostate then contracts, releasing alkaline fluid to safeguard sperm in the acidic vaginal environment.
00:16Seminal plasma, containing nourishing sugars, remains in the vagina.
00:22Sperm navigates cervical mucus to reach the uterus, and fertilization typically occurs in the fallopian tube.
00:30The fertilized egg transforms into a zygote, rapidly dividing before journeying to the uterus.
00:45Upon reaching the uterine wall, the blastocyst embeds itself, prompting the ovaries to halt egg release.
00:51It progresses from a blastocyst to an embryo, and eventually a fetus.
00:57Around weeks 9 to 12, distinct facial features emerge, and vital organs advance in development.
01:04The circulatory system, brain, and spinal cord take shape.
01:08By week 12, the fetus measures around 5 cementer, weighs approximately 14 gri, and continues maturing until birth.
