Detecció i incidència d'anomalies cromosòmiques en espermatozoides humans
, 2000 Fluorescent in situ hybridization methodology allows analyzing the chromosome content of spermatozoa. With the analysis of the gametes, it is possible to determine the real risk of transmission of a chromosome abnormality to the offspring.We have used this methodology in the cytogenetic study of human spermatozoa obtained from two types of men; control

Therapy for patients with severe oligozoospermia is the intracytoplasmic sperm injection (ICSI). However, its high cost limits its application in countries whose health systems do not cover this medical technique. The new vitrification technique makes it possible to store sperm after sperm selection until reaching the minimum concentration for cycles ...
