Endometriosis is a disease that affects 10 to 15% of the women of reproductive age. It is characterized by the presence of endometrial-like tissues outside of the uterus. Some definitions claim that the functional ectopic tissue is sensitive to the action of hormones. Severity of endometriosis is defined according to a system proposed by the American Society for Reproductive Medicine, which is based on laparoscopic findings.
Infertility as a psychological problem has gained increasing attention. Male partners among infertile couples have elevated levels of psychological distress, which could affect semen quality, result in hormonal abnormalities, and increase the occurrence of early miscarriage. Infertile women are more vulnerable to psychological distress and require psychological support. Subfertile women who conceive after assisted reproduction have higher stress, anxiety, and depression levels. Psychological interventions have been shown to have beneficial effects on infertility patients.
In the present study, we report on the case of a 43-year-old male patient seeking for fertility assistance, who showed a seminal analysis and testicular biopsy of complete azoospermia. Peripheral blood culture for chromosome studies revealed a karyotype of 46 chromosomes with a ring-Y-chromosome that lost the long arm heterochromatin. Molecular analysis of genomic DNA from the patient detected the presence of the sex-determining region of the Y-chromosome (SRY) but the complete absence of regions involved in spermatogenesis (AZFa, AZFb, AZFc).
