Abstract

Studies indicate abnormal semen indicators among varicocele infertile men can be reversed to normal status after surgical repair. While semen indicators and DNA damage of sperms are reported frequently, sperm function tests are rarely performed to assess the functional status of sperms among these individuals. We report a 35-year-old male with 4 years of primary infertility who otherwise has a normal sexual life. Various analyses performed revealed the interplay of multiple abnormalities leading to the observed phenotype. The individual was diagnosed with severe sperm defects, bilateral varicocele (grade II) and endocrinopathy. The percentage of functionally normal sperms were found to be 24% for hypo-osmotic swelling, 28% for acrosome reaction and 21% for nuclear chromatin decondensation test. Cytogenetic analyses showed normal karyotype and sequence-tagged-site markers based PCR showed no deletions involving key candidate genes of the Y chromosome. A thorough investigation of infertile subjects and simple diagnostic tests are essential to detect the treatable defects, in general as well as severe infertile cases, which can improve the chances of normal conception or the success rates of in-vitro fertilization and intracytoplasmic sperm injection.
