The answer to what "eats a sperm" depends on whether you are asking about a sperm cell or a sperm whale.
1. If you are asking about a sperm cell:
Sperm cells are consumed by various components within the female reproductive tract after intercourse or artificial insemination. This consumption is a natural part of the reproductive process.
-
Immune cells: The female's immune system recognizes sperm as foreign cells. White blood cells, such as macrophages, engulf and digest sperm cells to prevent infection and maintain homeostasis. This is a key mechanism in regulating fertility.
-
Epithelial cells: Cells lining the female reproductive tract can also engulf sperm cells.
-
Other sperm cells: In rare cases, defective sperm may be consumed by other, healthier sperm, although this is not a primary mechanism of sperm removal.
The purpose of this removal is to prevent polyspermy (fertilization of an egg by multiple sperm), eliminate defective sperm, and generally clear the reproductive tract.
2. If you are asking about a Sperm Whale:
The primary predator of sperm whales is the killer whale (Orca).
- Killer Whales (Orcas): Killer whales, particularly those that hunt in pods, target sperm whale calves and, less frequently, adult females. They are known to separate calves from their mothers and attack vulnerable individuals. Adult sperm whales will form defensive circles around vulnerable members of their pod to protect them from killer whale attacks.
In summary, while immune cells and other biological components "eat" sperm cells, killer whales (orcas) are the primary predators that "eat" sperm whales.
