Details and patient eligibility

About

Couples referred for microdissection-TESE (m-TESE) due to Klinefelter's syndrome, maturation stop in the spermatogenesis, or failed retrieval of testicular spermatozoa by conventional techniques with needle or TruCut are included. The women are stimulated with FSH in IVF protocols and the aspirated oocytes vitrified with usual applied techniques. Fresh sperm retrieved by micro-TESE are used for fertilization of the warmed oocytes. when it is not possible to obtain testicular sperm, the couples are offered fertilization with warmed oocytes.

Fertilization, cleavage, implantation and pregnancy rates using sperm from the patients versus from sperm donors will be compared.

Trial design

100 participants in 2 patient groups

Study group
Description:
Couples where the men have Klinefelter's syndrome, maturation stop in the spermatogenesis or failed retrieval of testicular sperm by conventional techniques with needle or TruCut, and where testicular sperm could be obtained by micro-TESE.
Control group
Description:
Couples as in the study group, but where testicular sperm could not be obtained by micro-TESE. The oocytes therefore must be fertilized using donor sperm.
