Is There A Need For More ‘Male Birth Control’?

The world population has passed 7 billion this year. It is growing at 75 million per year. It is a startling fact that 1 in 2 pregnancies are unplanned/unintended. Half these pregnancies are due to failure to use contraception and the other half is because of difficulties with contraception use or failure of the method.  Most options for family planning are focused on the female partner. The options for male contraception at the present time are abstinence, withdrawal methods and condoms as a reversible options and vasectomy for permanent sterility. In this article we review the issue of male contraception and the options for men to participate in the prevention of unplanned pregnancies.

The National Survey of Family Growth (NSFG) has shown that most women (99%) ages 15-44 have used some for contraception at some time either the pill or condoms. The type of contraception a couple/person uses is very much dependent on what stage of a relationship or life is ongoing. In early sexually active life, the main objective is reversible contraception, and prevention of sexually transmitted infections (STDs). To achieve this, options include the use of condoms and/or  a female method of birth control e.g. the pill, diaphragm, intrauterine device. The intrauterine device, such as Mirena is an option that lasts several years and comes with more risks, according to Consider the Mirena side effects as they are different than the pill or a diaphragm.  As a couple becomes more stable in a relationship, prevention of STDs becomes less of a concern but maintaining the ability to prevent pregnancy. This results in the use of a reversible form of contraception that may include the condom or female methods as outlined. The next stage of life is when a stable relationship may result in consideration of a more permanent contraception option.  At this time, vasectomy for the man or tubal ligation for the women (having her “tubes tied”) is considered. Such choices are very individual for men and women and include issues of trust and promiscuity.  The prevailing theory in the general population and community is that contraception is more important to women since they are primarily involved with pregnancy. It is because of this mindset that female contraception is much more advanced in choices with the female birth control pill having its 50th anniversary in the last year. A number of studies have actually shown that men have both an interest and feel a responsibility for contraception. The current contraceptive choices for men are still somewhat limited. They include abstinence, withdrawal technique, condom or vasectomy.  Condoms have been around for centuries with advances in the 20th century with the creation of latex rubber.  The failure rate of condoms is quoted as one in fifty for perfect use; 15% for “typical use” and breakage or slippage in 2-9%.  Percentage of high school students, who used a condom during their last sexual intercourse in the United States, has gone from 4 in 10 (40%) in 1991 to just over 6 in 10 (60%) in 2007. Although this is an improvement, it is not good enough and we need to continue to educate teenagers on prevention of teen pregnancies.  Condoms also remain the most effective method to prevent STDs/HIV.

Vasectomy practice in the USA reveals that approximately 527,000 vasectomies were performed in 2002. Vasectomy use has leveled out since the 1980s – approx 10/1000 men aged 25-49. Vasectomy is a minimally invasive procedure that causes minimal discomfort and has a very high success rate. It is a great option for couples who are finished with their family planning. This must be considered a permanent option although a small percentage of men (6 of 100 or 6%) may consider fertility after vasectomy usually related to a new relationship and new partner.  Men who have a vasectomy are not   cleared of the risk of sexually transmitted diseases. A recent study has shown that men who have had a vasectomy are less likely to wear a condom for STD prevention.

The American Urological Association recently came out with guidelines on vasectomy. Post vasectomy sperm check is essential. This is important 15-20 ejaculations and 8-12 weeks from the time of vasectomy. Early or late reconnection of vasectomies do occur which is why waiting to check the sperm count until after approximately 3 months is recommended. The failure rate from a vasectomy is either measured in terms of sperm still being present in the semen after a vasectomy or pregnancy risk. The pregnancy risk after a vasectomy is 1 in 2000, which is the same to less risk of pregnancy for a women who has her “tubes tied”.

  • In the future, a number of issues need to be addressed for contraception for men (and women): Better education on compliance for contraception along with increased personal responsibility
  • Better public awareness of options
  • Better access to options
  • Development of a reversible male contraceptive other than condoms. With this, options to prevent STD’s are still not addressed.
  • Male and female opinion on compliance/trust issues

With the female pill being over 50 years old, development of a reversible “male pill” is ongoing, with extensive research being sponsored by several organizations. Overall, contraception is an important choice and as such, patients and providers a like need to be aware of choices.
