Contraceptive may cause women to choose the wrong partner

Yet another reason to steer clear of artificial contraceptives: the pill may cause women to choose the wrong partner.

"Wrong", in this case, refers to a union that results in offspring with sub-optimal immune systems.

Apparently, this level of partner selection is influenced by pheromones. Chemical contraceptives disrupt this process.

From the article:

The pill is thought to disrupt an instinctive mechanism that brings together people with complementary genes and immune systems.

By passing on a wide-ranging set of immune-system genes, they increase their chances of having a healthy child who is not vulnerable to infection. Couples with different genes are also less likely to experience fertility problems or miscarriages.

Women are naturally attracted to men with immune-system genes different from their own because of their smell, experts believe.

The major histocompatability complex (MHC) cluster of genes, which helps to build proteins involved in the body’s immune response, also influences smell signals called pheromones.

Although pheromones may be almost unnoticeable at a conscious level, they can exert a potent effect.

  2. The pill, like other contraceptives, has many negative side effects. This is one of the "minor" ones, I guess.

    Another is that the pill can also be an abortifacient since it does not always prevent ovulation and consequently does nothing to prevent the sperm and egg from uniting. In such cases, it also affects the uterine lining, creating a "hostile endomentrium" which keeps the fertilized egg from implanting. Thus, with nowhere to implant, the newly-conceived person is eventually destroyed, which is an early chemical abortion.

  3. You know its a wrong partnership when parents keep having babies and can't afford to give them the most basic of needs, like food and education.
    The Philippines needs somebody aggressive to push Family Planning programs no matter what the church says. Natural contraception ??? Obviously, it hasn't worked !!!
