A lot of potential male contraceptive drugs are available. Some of them are accepted by the government for treatment of other diseases whereas others still developing. (ex: the nifedipine, a drug for hypertension and migraine. Immunocontraceptive, a contraceptive vaccine which still developing.)
 
Nifedipine: This drug is an hypertension and migraine medication taken as a daily pill. It is manufactured by six major pharmaceutical companies 
 
the dry pill: It changes the way the smooth muscles of the vasa deferentia have during an ejaculation and it disturbs the transport of sperm. Indeed, the vasa deferentia have two different types of smooth muscle: circular muscle fibers and longitudinal muscle fibers. Usually, the two muscles work together to move sperm toward the urethra. But if pieces of vasa deferentia have been exposed to phenoxybenzamine or thioridazine in the lab, the longitudinal smooth muscle fibers will contract. (see annexe ..)
 
the immunocontraceptive:  it is a contraceptive vaccine and still developing in India, Europe and the US. It already exists for women.

What kind of male contraceptive techniques are available?

Indeed many male contraceptives, as condom and vas occlusion methods, are used by men to avoid diseases and to reach birth control. Nowadays, scientists are searching for a new contraceptive: the male pill. This new solution will actually be our main focus. We first are going to describe the most current methods that men use and then present the future male pill.

Most men choose the condom as a contraceptive because they often find that vasectomy is a too radical solution. Some others prefer vasectomy for several reasons.



  • available methods for men: condoms and sterilization
  • some men don't like condoms for several reasons
  • vasectomy = sterilization... so everybody won't use this technique
so... which are the other methods that can be used by men: one direction to follow is the MALE PILL



  • Condom
Condom is the contraceptive the most used by men. It is a thin device usually made of latex or plastic worn on penis during sexual relations. Condoms are also used by women.

  • Vas occlusion methods
Vas occlusion, also called vasectomy, is a simple surgical procedure in which the tubes (vas deferens) that deliver the sperm from the testes are cut and close off. This short surgery usually causes few complications and doesn't change anything in sexual functions.
For more informations : Sterilization

These can be considered as contraceptive even if these are rarely used for this.

  • Pharmaceutical methods

A lot of potential male contraceptive drugs are available. Some of them are accepted by the government for treatment of other diseases whereas others still developing. (ex: the nifedipine, a drug for hypertension and migraine. Immunocontraceptive, a contraceptive vaccine which still developing.)

Why are we always searching for new male contraceptive methods?

Nowadays both men and women want that men participate as much as women in family planning. That's why we are searching new male contraceptives. One of the main reason is that abortion rates still high. Indeed a contraceptive 100% efficient doesn’t exist so accidents are always occurring (more than 20% of pregnancies end in abortion each year in USA). Moreover, ideal contraceptive doesn’t exist either. But the problem is that as the world is developing, people’s needs become more and more important. However, these kind of reasearches are long and difficult to reach and many of them are revealed unsuccessful.
