Is Virgin Birth Possible in Humans?
While extremely unlikely, a human virgin birth is theoretically possible. This refers to parthenogenesis, where an egg develops into an embryo without fertilization by sperm. However, several significant biological hurdles exist.
Several studies have touched upon the rarity of parthenogenesis in humans. One source states that "it's possible for a human baby to be born of a virgin mother, it's very, very unlikely," citing the extremely low probability of specific genetic deletions necessary for the process (approximately a one in a billion chance each, and this excludes other required biological steps).

The process requires two key genetic deletions, making it exceptionally rare. These genetic changes are critical for a successful parthenogenetic development, highlighting the significant biological obstacles. Additionally, research suggests that even with these genetic changes, other hurdles like calcium spike and division problems exist, making spontaneous human parthenogenesis highly improbable.
While some studies report claims of virgin births (e.g., a study reporting 0.8 percent of responders claiming to have given birth while virgin, and not using assisted reproductive technology), these claims are often questionable and may involve various confounding factors.

In contrast to the challenges in humans, parthenogenesis is known to occur in some animal species. Recent scientific breakthroughs have identified specific genetic triggers in other animals that enable parthenogenesis, and some have even managed to trigger it artificially in the lab. However, these findings don't imply immediate applicability to humans. [Source: ScienceDaily, Newsweek articles, July 2023]
Defining "Virgin Birth"
The term "virgin birth" can be ambiguous. It can refer to:
- Parthenogenesis: A biological process where an embryo develops from an unfertilized egg, requiring specific genetic changes.
- Miraculous birth: As described in religious texts, such as the birth of Jesus. This is outside the realm of scientific possibility.
The question should clarify whether the inquiry pertains to the biological possibility or a religious concept.
Conclusion
While biologically possible, a human virgin birth via parthenogenesis is exceptionally rare due to significant genetic and biological barriers. The probability is incredibly low.
