Study Notes
- During ejaculation, around 300 million sperms are released from the testes through the vas deferens, reaching the prostate where fluid is released to push semen through the urethra.
- Seminal fluid is alkaline to protect sperm from the acidic vaginal environment and contains enzymes to liquefy the gel and sugars to nourish the sperm.
- Sperm swim through cervical mucus to reach the uterus, where during ovulation, the environment becomes more favorable for sperm penetration.
- Fertilization typically occurs in the ampullar-isthmic junction of the fallopian tube, with contractions aiding sperm movement towards the egg.
- The first sperm enter the fallopian tubes shortly after ejaculation, with only a few surviving the journey to meet the egg.
- Upon contact with the egg, sperm burrow through cells, bind to the zona pellucida, release enzymes, and fuse with the egg membrane to prevent other sperm from attaching.
- The fusion of genetic material from the sperm and egg forms a zygote with a full set of chromosomal DNA, unique characteristics, and the potential to develop into a new person.
