Eligibility

Sex/Gender
All

Inclusion criteria

Inclusion criteria: The patients who had consented to participate in this treatment and satisfied the following conditions. 1. The round spermatid is their most advanced spermatogenic cell. 2. Testicular spermatozoa are dead, have head anomalies or the elongating and elongated spermatids are degenerative. 3. The number of collected oocytes from wives of patients that meet 1, 2 criteria is over five.

Exclusion criteria

Exclusion criteria: 1. In the case when even once a few spermatozoa have been found even if no spermatozoa are observed in other frequent analysis. 2. In the case when the possibility of obtaining round spermatids is near zero. 3. In the case when the surgical procedure for round spermatid collection is likely to deteriorate the patient's health. 4. In the case when the number of collected oocytes from patient's wife is less than five.
