Method characteristics
Situational context

• Male responsibility
• Sexual side effects
• Compliance
       What about women?
Dear ladies in the audience,

  Let us presume that you are in a stable
  heterosexual relationship,that you are fed
  up with daily taking of your OC and that
  there is a bi-weekly injectable male
  contraceptive that is safe and reliable as
  long as the injections are given in time
  (within 72h)
 Would you rely on this
method used by your male
        partner?
          Male Responsibility
• Men are more interested in avoiding unintended
  pregnancy than often assumed but lack information,
  communication skills and services
  (population reports ICPD 1998)

• The assumption that contraception, pregnancy,
  childbirth and prevention of STD are exclusively
  women’s concern reinforce men’s lack of
  involvement in safeguarding reproductive health
  (the state of world population, UNFPA 2000
               Male Responsibilty
• Compared to sexually active girls boys are
   significantly more likely to believe that
   contraception in general:
-interferes with sexual pleasure
-is bothersome
-involves too much planning
-is difficult to obtain
-makes others think they are seeking sex
(Pesa,Turner et al, J Pediatr 2001)
          Sexual Side Effects

    Condom

•   Interruption of foreplay
•   Sensory loss
•   Lack of experience
•   Rationalisation
        Sexual Side Effects

 Vasectomy

sexual functioning explain huge
differences in vasectomy rates
         Sexual Side Effects

  within physiological limits

  trials

        Compliance - vasectomy
• In western countries vasectomy rates vary
  from 0-35% in men > 40 years
  (female 170 million vs male 43 million)
                   * Health beliefs
                   * Shared responsibility

• 34% of men never show up for post-
  vasectomy screening
  (Maatman et. al, fertil. steril 1997)
 Compliance - hormonal methods
• Route of administration

• High continuation rates in clinical trials
  (e.g. WHO 1996)
