Female sperm

Female sperm can refer to either:

  1. A sperm which contains an X chromosome, produced in the usual way in the testicles, referring to the occurrence of such a sperm fertilizing an egg and giving birth to a female.
  2. A sperm which artificially contains genetic material from a female.

Since the late 1980s, scientists have explored how to produce sperm where all of the chromosomes come from a female donor.
