What method blocks sperm from reaching the egg?
What method blocks sperm from reaching the egg?
A condom acts as a physical barrier that prevents sperm from entering the uterus and reaching an egg. Two types are available: A male condom is a thin sheath made of latex (rubber), polyurethane (plastic), or natural (animal) membrane that is worn over the erect penis during sexual intercourse.
Which method of birth control works from blocking sperm from meeting the egg and or blocking bodily fluids passing from partners?
Using a spermicide with a barrier method gives you the best possible barrier method protection. The spermicide kills most of the sperm that enter the vagina. The barrier method then blocks any remaining sperm from passing through the cervix to fertilize an egg.
What method of contraception prevents ovulation?

Which is the privileged sperm to fertilize the egg?
Although this is an analogy, it actually works very similarly: while many sperms participate in the race, only one of them will be the privileged one that will fertilize the egg. We can split the journey into two different stages:
What happens to sperm during the race to the egg?
After the man ejaculates, the sperms begin a race where not only speed is crucial, but also resistance. Those with defects and/or poor motility will not make it to the end. Some of the obstacles the sperms will encounter include: Not every sperm cell is able to survive inside the vagina due to the acidic pH it contains.
How does sperm travel from the fallopian tubes to the egg?
The Fallopian tubes and the uterus use a suction force by creating rhythmic contractions, and the cervical mucous becomes less dense to allow the sperms to travel more easily. On the other hand, the seminal fluid that accompanies the sperms neutralizes the effect of acidic pH and secretes a sugar that nourishes the sperm.
How long does it take for an egg to fertilize sperm?
By Andrea Rodrigo BSc, MSc (embryologist). Fertilization can occur as long as there is an egg waiting for the sperm to fertilize it. An egg can survive for 12-24 hours, but sperm can live up to 5 days or even longer inside the woman’s body.
