The rapidly evolving and often extraordinarily complex appearance of male genital morphology of internally fertilizing animals has been recognized for centuries. Postcopulatory sexual selection is regarded as the likely evolutionary engine of this diversity, but direct support for this hypothesis is limited. We used two complementary approaches, evolution through artificial selection and micros...

Genitourinary system is the most common extrapulmonary site after lymph node involvement affected by tuberculosis (TB). TB can affect whole male genital organs; epididymis, testis, prostate, seminal vesicle, vas deferens, scrotal skin, bulbourethral glands and penis. Although male genital TB (MGTB) is reported rarely in the literature, most of the cases are overlooked. It is not always very eas...

Four hundred and sixty-seven male patients with leprosy were screened for genital involvement. Genital lesions were observed in 6.6% of all male cases of leprosy. They were seen most frequently in lepromatous leprosy (25.8%), followed by borderline lepromatous (13.3%) and borderline tuberculoid (1.4%) leprosy.

Rapid and divergent evolution of male genital morphology is a conspicuous and general pattern across internally fertilizing animals. Rapid genital evolution is thought to be the result of sexual selection, and the role of natural selection in genital evolution remains controversial. However, natural and sexual selection are believed to act antagonistically on male genital form. We conducted an ...

The male genital examination is a simple and quick clinical assessment and is important for screening and diagnostic purposes beyond the need to screen for testicular cancer. Despite the lack of evidence supporting screening for testicular cancer, the genital examination should be included as part of a male's routine physical examination, as well as when a male patient presents with genital com...

In 1983, during the earliest days of AIDS research, Deborah Anderson and her colleagues in Boston, Massachusetts hypothesized that AIDS was transmitted by virallyinfected "Trojan horse leukocytes" in semen [1]. This prediction has been supported by numerous studies over the past two decades, although many questions remain concerning HIV infection of the male genital tract. In this issue of AIDS...

PATHOLOGY OF THE MALE GENITAL SYSTEM Objectives:  Describe the penile neoplasm.  Identify the histological features of testicular atrophy associated with infertility cases.  Identify the gross appearance of hydrocele and torsion of testis.  Describe the classification and the histogenesis of Testicular tumors.  Identify the gross and histological features of: Benign prostatic hyperplasia. ...
