No, biological male pregnancy, in the traditional sense, is not possible in humans. Pregnancy requires a uterus, an organ found in females. A cisgender man, biologically defined as a person with male reproductive organs (testes, penis, etc.) lacks a uterus.
However, the answer is nuanced. The possibility of pregnancy exists for individuals assigned male at birth (AMAB) who have:
-
Uteruses: Some transgender men and non-binary individuals retain a uterus following assignment of male sex at birth. These individuals are capable of pregnancy. https://www.healthline.com/health/transgender/can-men-get-pregnant
-
Future Technological Advancements: Emerging technologies like uterus transplants may one day allow individuals without a uterus to carry a pregnancy. https://www.healthline.com/health/transgender/can-men-get-pregnant This remains speculative at present.
It's crucial to distinguish between biological sex and gender identity. While the term "male pregnancy" might be used colloquially to refer to pregnancy in transgender men, it's more accurate to discuss pregnancy in individuals with a uterus, regardless of their gender identity. The ability to become pregnant is determined by the presence of a functional uterus, not the individual's gender identity or perceived sex. https://www.medicalnewstoday.com/articles/can-men-become-pregnant
Several sources emphasize the necessity of a uterus for pregnancy:
- "It is only possible for a person to be pregnant if they have a uterus. The uterus is the womb, which is where the fetus develops. Male reproductive organs..."
- "Any individual with a uterus and ovaries can get pregnant." https://www.healthline.com/health/transgender/can-men-get-pregnant
The concept of "male pregnancy" in non-human species exists, highlighting biological variations across the animal kingdom. However, in humans, pregnancy in individuals who have male reproductive organs at birth is currently only possible if they retain a uterus. https://en.wikipedia.org/wiki/Male_pregnancy
