The role of sexual selection in fuelling genital evolution is becoming increasingly apparent from comparative studies revealing interspecific divergence in male genitalia and evolutionary associations between male and female genital traits. Despite this, we know little about intraspecific variance in male genital morphology, or how male and female reproductive traits covary among divergent popu...

Human immunodeficiency virus type 1 (HIV-1) in the male genital tract may comprise virus produced locally in addition to virus transported from the circulation. Virus produced in the male genital tract may be genetically distinct, due to tissue-specific cellular characteristics and immunological pressures. HIV-1 env sequences derived from paired blood and semen samples from the Los Alamos HIV S...

Hypospadias is the most common anomaly in the male genital tract with an incidence of 0.8-8.2 per 1000 live male births. Routinely, hypospadias cases are repaired after one year of age, and it is recommended that a child with hypospadias not to be circumcised until hypospadias repair is completed. This study was conducted to determine whether or not circumcision prior to hypospadias repair incr...
