There is no need for a male partner for the egg freezing process. However, men can freeze their
sperm for any future use. The most common fertilization method is cryopreservation. During this
process, oocytes and embryos are frozen under low pressured liquid nitrogen. The cold
conditions can freeze them easily. Then, we manage it with vitrification. Vitrification is a
process where we prevent the liquid from converting into solid, as the highly concentrated
embryos have viscosity. The overall process is effective for assisted reproduction
