Male genital mutilation is a common mechanism by which males reduce sperm competition by plugging female insemination ducts with different parts of its own genital system. This behavior is frequent in many spider families but is uncommon in Haplogynae. The reproductive biology of Dysderoidea is not well studied and the data is fragmentary; male genital mutilation has been reported only for one ...
Genital surgery is one of the most controversial and contested practices, yet it is frequently described and referred to with little or no attention to cultural and social context. This article examines the practice, performed on both men and women, and the extent to which it clashes with issues of consent and capacity, as well as multicultural concepts of toleration for minority group practice...
In a preindustrial context, the mate choices of women are controlled by their parents, who require evidence of wealth and of ability to generate wealth from prospective sons-in-law in order to grant access to their daughters’ reproductive capacity. As a consequence, male siblings have to compete among themselves for controlling family resources required for successful reproduction. This competi...
Voluntary medical male circumcision (VMMC) decreases the risk for female-to-male HIV transmission by approximately 60%, and the President's Emergency Plan for AIDS Relief (PEPFAR) is supporting the scale-up of VMMC for adolescent and adult males in countries with high prevalence of human immunodeficiency virus (HIV) and low coverage of male circumcision.

BACKGROUND Male circumcision is associated with reduced HIV acquisition. METHODS HIV acquisition was determined in a cohort of 5507 HIV-negative Ugandan men, and in 187 HIV-negative men in discordant relationships. Transmission was determined in 223 HIV-positive men with HIV-negative partners. HIV incidence per 100 person years (py) and adjusted rate ratios (RR) and 95% confidence intervals (...
BACKGROUND Interferon has been widely used in the treatment of genital warts for its immunomodulatory, antiproliferative and antiviral properties. Currently, no evidence that interferon improves the complete response rate or reduces the recurrence rate of genital warts has been generally provided. The aim of this review is to assess, from randomized control trials (RCTs), the efficacy and safet...
BACKGROUND Health care spending is known to be highly skewed, with a small subset of the population consuming a disproportionate amount of health care resources. Patients with cancer are high-cost users because of high incremental health care costs for treatment and the growing prevalence of cancer. The objectives of the present study included characterizing cancer-patient trajectories by cost,...
