The optimal approach for finding spermatozoa in testicular tissue in patients with nonobstructive azoospermia is microdissection Testicular Sperm Extraction
These men are informed about the possibility of testicular sperm extraction
and ICSI combined with cryopreservation of the testicular tissue.
In vitro production of haploid cells after coculture of CD49f+ with Sertoli cells from testicular sperm extraction
in nonobstructive azoospermic patients.
This literature review reveals that sperm retrieval appears necessary in the presence of many sex chromosomal abnormalities, whereas patients with autosomal chromosomal abnormalities are often oligospermic and thus do not require testicular sperm extraction
. Further, it appears that for patients with sex chromosomal abnormalities, including those with Kleinfelter syndrome, sperm retrieval combined with assisted fertility treatment offers a good prognosis for pregnancy.
