Male Contraceptive Injection

Kirsty • From Wales, UK. 24 and in a relationship!
A trial has been carried out on 350 men who I assume are in a relationship. Out of the 350 men, 4 couples became pregnant after solely relying on this injection. However due to side effects changes are needed. "But scientists say more work is needed to tackle side effects - including depression, acne, and increased libido - before it is made more widely available." What does everyone think?
