A Prospective Study on Klinefelter Syndrome: A Basket of Multiple Systemic Disorders in a Tertiary Care Hospital

ABSTRACT

Background: When one or more extra X chromosome is added to a normal male karyotype (46-XY), then a new aneuploidy appears called Klinefelter Syndrome (KS). Every day approximately more than 50 new such cases are added in the male population of India. Traditionally they are lean, thin, tall, azoospermic, hypogonadic, infertile males with low social and educational profile. As the age advances level of testosterone decreases and many new symptoms of multiple systemic disorders appear in these cases. Methods: A well designed questionnaire of infertile males attending the above- mentioned OPD’s was filled with history, clinical examination and semen analysis (twice as per the WHO criteria).  Results: In our series of 500 azoospermic males, we encountered 56 classical KS cases (11.2 %) of 47-XXY karyotype, who were hypergonadotrophic hypogonadic and diagnosed with multiple diseases when evaluated in detail. Conclusions: Hence, every KS must receive androgen replacement therapy, which should begin at puberty and continue for lifelong that helps in preventing the development of high comorbidity rate and premature deaths because these are very high in such condition as compared to normal male population.
