Sperm cryopreservation in adolescents and young adults with XXXX : results of the French national sperm banking network (CECOS).

@entity5 @entity1
OBJECTIVE: To determine the feasibility of fertility preservation in adolescent males with @entity5 . DESIGN: Large multicenter retrospective study of male @entity1  <=20  years from 23 centers of a national network of sperm banks over a 34-year period. SETTING: Sperm banks. @entity1 (S): A total of 4,345 @entity1 and young @entity1 aged 11 to 20 years. INTERVENTION(S): Age, @entity5 diagnosis, feasibility of sperm banking, and sperm parameters. MAIN OUTCOME MEASURE(S): Description of @entity1 , and success of their fertility preservation. RESULT(S): We observed a mean yearly increase in referred @entity1 of 9.5% (95% confidence interval, 9.1%-9.8%) between 1973 and 2007. Over the study period, the percentage of younger @entity5 @entity1 who banked their sperm increased, especially in the 11-14  year age group, rising from 1% in 1986 to 9% in 2006. We found that 4,314 @entity1 attempted to produce a semen sample, 4,004 succeeded, and sperm was banked for 3,616. The mean total sperm count was 61.75 * 10(6) for the 11-14  year age group, and 138.81 * 10(6) for the 18-20  year age group. It was noteworthy that intercenter variations in practices involving young @entity1 seeking to preserve their fertility before @entity5 therapy were observed within this national network. CONCLUSION(S): Our results emphasize the need for decisive changes in public health policy to facilitate the access to reproductive health-care for young @entity5 @entity1 .
