Male Contraceptive Pill Works–But Side Effects Halt Trial

October 27, 2016

(New Scientist) – An injected male contraceptive has been shown to be almost 100 per cent effective in a trial involving 320 men. The hormone-based jab is designed to lower sperm counts by acting on the brain’s pituitary gland. Over a year-long trial, the injection was effective in nearly 96 per cent of couples. However, researchers said more work was needed to address the treatment’s reported side effects, which included depression and other mood disorders, muscle pain, acne and increased libido. The side effects caused 20 men to drop out of the trial.
