Is giving birth less painful for animals?

It’s impossible to quantify exactly how much pain this causes, but giving birth to larger offspring tends to be more dangerous and to result in more tearing. For other animals, the size of the offspring isn’t as big a problem. Litter-bearing species pass more offspring, but each infant tends to be pretty small.

Why is birth more dangerous for humans than for other animals?

Human births are far more dangerous than those of other mammals or even other primates. The human brain is three to four times bigger than an ape’s brain. And the pelvis is narrower to allow us to walk upright. A human baby has to go through considerable contortions to make it through the narrow opening.

Do all mammals feel pain when giving birth?

Virtually all human mothers experience pain in childbirth, and delivery takes much longer than in other mammals. For example, in University of New Mexico researcher Leah Albers’s 1999 study of 2,500 full-term births, labor lasted on average almost nine hours for first-time mothers.

Why is childbirth so difficult for humans?

Prior research has suggested the reason childbirth is so much more difficult in humans compared to apes or other animals is because we evolved to walk upright, and because our babies have very large heads. As humans developed an upright gait, our pelvises changed in ways that made the birth canal narrower.

Why is childbirth so painful?

Pain during labor is caused by contractions of the muscles of the uterus and by pressure on the cervix. This pain can be felt as strong cramping in the abdomen, groin, and back, as well as an achy feeling. Some women experience pain in their sides or thighs as well.

Why does birth hurt so much?

Do humans have the most difficult birth?

Humans have a relatively hard time giving birth. Compared with other species, human newborns are large for their birth canal. This means that humans face the surprisingly high risk of our babies getting stuck during labor—which can be fatal for the mother, the newborn, or both.
