The polymorphic variants G919A and A2039G of the FSHR gene in men with azoospermia were investigated. In the nonobstructive form of azoospermia, the frequency of homozygotes GGAA, GGGG, and AAAA was 1.8–3.2 times higher than theoretically expected. In men with nonobstructive azoospermia, the highest level of follicle stimulating hormone (FSH) in serum was observed in homozygotes for the polymorphic...
An analysis of numerical anomalies of chromosomes 13, 18, 21, X, and Y was carried out using the FISH method before in vitro fertilization in the sperm nuclei of patients with astheno-, oligo, and teratozoospermia. The percentage of aneuploid spermatozoa was significantly higher (p < 0.05) in patients with oligozoospermia compared to patients with astheno- and teratozoospermia. A significant difference...
