Abstract/OtherAbstract:
The aim of this study was to evaluate the incidence of spermatic aneuploidies in men with severe teratozoospermia and to determine an eventual relation between aneuploidies and a specific morphology of spermatozoa. Fluorescence in situ hybridisation (FISH) using a probe cocktail containing the alpha satellite for the centromeric region of chromosome X, Y and 18 was performed on decondensed spermatozoa from fresh ejaculates of thirty patients with severe teratozoospermia (abnormal forms >80%) and 15 fertile men with normal semen profiles. The mean frequency of teratozoospermia in patients was 91 ± 6.99%. There was statistically a significantly increased frequency of 1818, XY, XX and YY disomies in sperm with severe teratozoospermia compared with normal sperm (1.24% versus 0.08%, 1.42% versus 0.31%, 1.13% versus 0.19% and 1.11% versus 0.24%, respectively, P < 0.001 in all comparisons). The rate of total diploidy was significantly increased in patients compared with controls (1.46% versus 0.16%, P < 0.001). There was a correlation between macrocephalic spermatozoa and diploidy (r = 0.37, P < 0.05). Our data add further evidence that patients with severe teratozoospermia have an increased sperm aneuploidy rate and that this is particularly high in macrocephalic spermatozoa; FISH analysis on sperm could help to improve risk assessment and reproductive counselling in these individuals who are frequently candidates for intracytoplasmic sperm injection (ICSI) as a treatment of their infertility, as the use of ICSI has created consequential debate concerning the genetic risk for the offspring.
