Drugs that can impact male fertility
When it comes to male fertility, there are certain drugs that can have an effect on the reproductive system. One such group of drugs is calcium channel blockers, which function by blocking calcium channels in the body. These medications are commonly prescribed for conditions like hypertension, coronary artery disease, angina, arrhythmia, and Raynaud’s disease. However, the use of calcium channel blockers can alter the way sperm metabolizes lipids, rendering the sperm unable to successfully fertilize an egg. It is important to note that this effect is not permanent and can be reversed.
Phenoxybenzamine is another drug that can impact male fertility. Unlike calcium channel blockers, Phenoxybenzamine specifically blocks ejaculation without affecting the quality of semen. It is worth mentioning that the effects of this drug on male fertility are also not permanent and can be reversed by discontinuing its use.
Vas-occlusive contraception
Vas-occlusive contraception is a method of birth control that involves the use of devices and plugs inserted into the vas deferens to block the passage of semen. The vas deferens is the tube that connects the epididymis to the urethra, allowing semen to be ejaculated. By blocking the vas deferens, this method partially or completely reduces the amount of semen ejaculated by a man, thereby reducing his ability to impregnate his partner.
It is important to note that unlike a vasectomy, which is a permanent form of contraception, blocking the vas deferens with devices or plugs is not permanent. These devices can be removed to restore normal fertility if desired. Clinical trials for the intra-vas device, a specific type of vas-occlusive contraception, were approved in 2006. These trials aim to provide more information about the success rates and potential side effects of this method.
