Why don’t Roosters Have a Penis?

Farmers have known roosters, along with 97% of all bird species, lack a penis. However, scientists recently discovered the reason birds such as roosters never develop a penis.

Rooster genitals start to develop in vitro, but eight or nine days into the embryo’s development the genitals are affected by a protein that promotes cell death.

It triggers the cells in the embryos penis to die faster than they grow back, eventually leaving a slight bulge instead of a penis. This process is linked to the switching on of a gene called Bmp4.

The quick answer is both partners procreate using an external orifice called a cloaca.

The longer answer to how roosters and chickens mate is…

A rooster begins a mating session by dancing around, dragging his wings on the ground in front of a hen. The hen will squat, preparing herself to be mounted by the rooster.

Once the rooster is firmly in place atop the hen, sperm is transferred quickly without penetration: the cloaca of both partners touch and sperm is exchanged in what is termed ‘a cloacal kiss’. The image above shows how this process takes place.

Rooster Testicles

Although, roosters got short-changed in the penis department, their testicles fare a bit better. They’ve got two bean-shaped testes located against their backbone in front of the kidneys which produces the sperm sent from the roosters cloaca to the hens cloaca during mating.
