For IVF, biopsied and frozen sperm is as effective as fresh

Some men with very severe infertility (with either very little or no sperm in their semen due to testicular failure, cancer or genetics) are unable to have their own children through IVF without being biopsied. In these cases a small needle biopsy is used to extract some tissue from the testicles and then a if sperm cells are found, they can be extracted and used in IVF.

Sperm taken by biopsy from the testicles of men with no sperm in their semen and then frozen can be as effective as fresh sperm taken by biopsy for helping couples to conceive through in vitro fertilisation (IVF).
