Genetic studies in varicocele infertility. II: Dermatoglyphic pattern.

The prime concern of the present work was the analysis of dermatoglyphic patterns in infertile patients presenting with clinically detectable varicocele. In a controlled study conducted on 30 patients and utilizing a slight modification of the original ink method of Cummins and Midlo, the dermatoglyphics on terminal phalanges of the thumb in both hands showed significantly higher incidence of the whorl pattern. Likewise, the index finger in both hands exhibited higher incidence of both the whorl and double loop patterns.

Genetic studies in varicocele infertility: I: pedigree, nuclear sex and seminal nucleic acids.

The hereditary predisposition of varicocele men to develop infertility was investigated in a controlled study involving 30 infertile varicocele patients. Analysis of the pedigree charts, determination of sex chromatin constitution, and biochemical measurement of seminal nucleic acid (DNA/RNA) were undertaken. Sibs and Kins of infertile varicocele patients showed various developmental anomalies particularly of the genito-crural area.
