Females become sexually mature at 10-12 years old, while males at 11-13 years. Female gorillas can reach sexual maturity years earlier, even at 7-8 years old, and can have their first ovulatory cycle even during their sixth year of life, but they do not start breeding until they are ten years old or later.

What season do gorillas mate?

Gorillas may breed year round. Females are in estrus for 1 to 2 days per month and only the dominant silverback has breeding rights. Gorillas are polygamous in nature because the dominant silverback mates with several females in his troop.

Do gorillas mate in different positions?

“Researchers say that few primates mate in a face-to-face position, known technically as ventro-ventral copulation; most primate species copulate in whats known as the dorso-ventral position, with both animals facing in the same direction,” explained a statement from WCS.

At what age do gorillas reproduce?

The bond between the silverback and his females forms the basis of gorilla social life. Females become sexually mature around seven or eight years old but dont begin to breed until a couple of years later. Males mature at an even greater age.

How does a gorilla mate?

Mating is done while both gorillas are on the ground with the female (which is normally smaller than the dominant silverback) appearing to kneel on the ground while the male is on top throughout the copulation.

Why do female gorillas mate with multiple males?

Female gorillas use sex as a tactic to thwart their rivals, new research suggests. “It seems to us that mating is another tactic that females use to compete with each other – in this case to gain favour with another male,” says Diane Doran-Sheehy, a primatologist at Stony Brook University in New York.

Do male gorillas mate with their offspring?

“The probability of a dominant male siring his daughters offspring is effectively zero, while on average he has almost two-to-one odds of siring any other offspring,” says Vigilant. Despite being much smaller than adult males, female gorillas actively make mate choices and initiate a large proportion of copulations.
