A barrier contraceptive
like sperm
Horse sperm is very similar to human sperm in morphology.
The sperm duct in an earthworm is responsible for transporting sperm from the seminal vesicles to the genital pores of another earthworm during copulation. This allows for the transfer of sperm from one worm to another for reproduction to occur.

In worms, sperm sacs serve as the storage site for sperm produced by the male reproductive system. These sacs store the sperm until it is transferred to the female during mating, allowing for efficient fertilization of eggs.
The barrier method
Barrier methods, such as condoms and diaphragms, physically prevent sperm from reaching the egg by creating a barrier between the two. Spermicides are another type of contraceptive that work by immobilizing or killing sperm before they can reach and fertilize an egg.
Barrier contraceptive methods physically prevent sperm from reaching the egg, such as condoms and diaphragms. Chemical contraceptive methods, on the other hand, utilize hormones to prevent ovulation or change the cervical mucus to inhibit sperm movement, like birth control pills or patches.

Potential steps to target for male contraceptive development could include blocking sperm production (spermatogenesis), inhibiting sperm motility or preventing sperm from reaching the egg by interfering with the process of fertilization. Additionally, targeting the fusion of sperm and egg (sperm-egg binding) or inhibiting the release of enzymes that allow sperm to penetrate the egg could also be potential strategies.
Barrier methods such as condoms, diaphragms, and cervical caps create a physical barrier that prevents sperm from reaching the egg. Additionally, spermicides can also be used to immobilize and kill sperm before they can fertilize the egg.
im doing reproduction in health and id like to ask you this qustion. What is a contraceptive method which is easy to buy; kill sperm
Yes, men who have had vasectomies still have DNA in their semen. The vasectomy procedure blocks the vas deferens, the tubes that carry sperm, preventing sperm from reaching semen. Semen is still produced by the body, but it does not contain sperm.
Vasalgel is a non-hormonal, long-acting contraceptive for men. It is a polymer gel injected into the vas deferens, blocking the passage of sperm while allowing other fluids to pass through. This prevents sperm from reaching the ejaculate, providing effective contraception.
