Testicular sperm aspiration (TESA) in 327 ICSI cycles.
OBJECTIVE
To evaluate the efficiency of testicular sperm recovery by testicular sperm aspiration (TESA) in an IVF program.


METHODS
Retrospective Data Analysis.


METHODS
The Center of Reproductive Medicine, Department of Obstetrics and Gynecology, Arcispedale S. Maria Nuova, Reggio Emilia, Italy.


METHODS
Couples undergoing TESA/ICSI for obstructive or nonobstructive azoospermia.


METHODS
ESA/ICSI.


METHODS
Efficiency of testicular sperm recovery, fertilization rate, implantation rate and clinical pregnancy rate.


RESULTS
Between March 1, 1997 and March 31, 2005, 327 cycles of TESA/ICSI were performed in couples in which the male had obstructive or nonobstructive azoospermia. The efficiency of testicular sperm recovery was 99.4% and 99.3%, fertilization rate 57.1% and 49.1%, implantation rate 5.7% and 6.2%, and the clinical pregnancy rate 12.9% and 15.4% in men with obstructive and nonobstructive infertility, respectively.


CONCLUSIONS
The efficiency of TESA is very high in both obstructive and nonobstructive azoospermia. Because TESA is less invasive than TESE, it should be considered a valuable alternative to TESE in IVF programs, especially in setting where resources are limited.
