However, a special property of a man's testicles is that they are immune-privileged , that is, a man's immune system will not attack foreign cells such as a woman's cells injected into the sperm-producing part of the testicles.

Thus, a woman's cells will remain in the man's testicles long enough to be converted into sperm.

However, there are more serious challenges. Biologists have well established that male sperm production relies on certain genes on the Y chromosome , which, when missing or defective, lead to such men producing little to no sperm in their testicles.

An analogy, then, is that a cell from a woman has complete Y chromosome deficiency. While many genes on the Y chromosome have backups homologues on other chromosomes, a few genes such as RBMY on the Y chromosome do not have such backups, and their effects must be compensated for to convert cells from a woman into sperm.

In , a patent application was filed [4] on methods for creating human female sperm using artificial or natural Y chromosomes and testicular transplantation.

In Chinese research scientists produced 29 viable mice offspring from two female mother mice by creating sperm-like structures from haploid embryonic stem cells using gene editing to alter imprinted regions of DNA.

Experts noted that there was little chance of these techniques being applied to humans in the near future. Scientists from the University of Newcastle upon Tyne led by biologist Karim Nayernia discovered a method of creating partly developed sperm cells, otherwise known as "spermatogonial" stem cells, from the bone marrow of male volunteers, entirely in-vitro outside the human body , and is seeking funding to see whether such techniques can be used to make female sperm.

If created, a "female sperm" cell could fertilize an egg cell, a procedure that, among other potential applications, might enable female same-sex couples to produce a child who would be the biological offspring of their two mothers.
