sex while breastfeeding destroys the milk

My question is if it is true or not that sex while breastfeeding destroys the milk? I don’t think so, but I want to know..?

Mom’s Question:

In Sierra Leone, lactating mothers fear to have sex. The general thought is that when one has sex during lactation the suckling child’s health deteriorates, even to fatality. It is a common belief that sex while breastfeeding destroys the milk and causes the child to have diarrhea, which becomes fatal.

Most of the time these things happen as it is said. As soon as the suckling mother starts having sex the child starts having frequent stools and sometimes dies shortly after. The causes (I think) is that once these mothers have got this notion; as soon as they have sex, they stop breastfeeding the child and start giving it foods (like rice, etc) that its system cannot tolerate.

In this direction, there is a need for wide publicity of the fact that one can have sex whilst breastfeeding without harming the child. This will go a long way in saving many children in Africa.

My question is if it is true or not that sex while breastfeeding destroys the breastmilk? I don’t think so, but I want to know..?

The Myth that Sex While Breastfeeding Destroys the Milk

Hi Saidu,

How interesting to read about this wide-spread folk myth in Sierra Leone, and also sad. I’ve heard about this myth before and the fact that many moms, therefore, believe in and follow “banfa” – the tradition to abstain from sex while breastfeeding, due to the belief that lovemaking while breastfeeding will harm the child.

Not having sex while breastfeeding is a perfectly fine choice and the libido while breastfeeding is often low for many women anyway, due to the breastfeeding hormones.

But when this fear to harm the child by having sex, means that the baby is weaned early, just to be able to have sex, then we have a problem! And the problem, of course, is even more severe if the child is then fed with foods that are not age-appropriate. Babies need either breast milk or properly prepared formula to be their main source of nutrition during their first year.

During their first six months of living, breast milk or correctly prepared formula should be their only food from the minute they are born. (WHO recommendation). Furthermore, the WHO recommends breast milk to be part of a baby’s diet until they are around 2 years old.

How Breast Milk is Affected by Sex

I have never encountered any studies showing that breast milk would deteriorate from lovemaking, and my view is similar to yours –  it is the worse diet after weaning that causes the children to get sick.

Sex has no connection with the breast milk more than possibly through the hormones that are released due to orgasm. The sperms remain at the level of the vagina and the uterus and never come anywhere near the bloodstream or the milk.

What does happen during orgasm, is that the woman’s body releases oxytocin, which is the same hormone that helps the letdown reflex while breastfeeding. So some women stat leaking breast milk during their orgasm. This is perfectly normal and has absolutely nothing to do with the quality of the milk.

The myth that sex while breastfeeding destroys the milk exists not only in Sierra Leone but in other countries too, such as for example Liberia, Ghana, and Tanzania, as well as in other African countries.

Conclusions on Sexual Intercourse and Breastfeeding

So, just to be clear:

It is perfectly safe for your child that you have sex while breastfeeding – as long as the person you have sex with is healthy. What I mean is that sexually transmitted diseases, such as HIV, can, of course, harm your child (and you!), but the sperm will not in any way destroy the breast milk or harm your child.

The World Health Organization (WHO) recommends exclusive breastfeeding for 6 months for very good reasons –  You can read about the benefits of breastmilk for both baby and mom here.

Thanks a lot for sharing! I hope you will be able to explain to some of your fellow moms that this myth that sex while breastfeeding destroys the milk simply isn’t true.

And I hope you will be able to stay strong and continue to breastfeed your baby even if and when you decide to start having sex again. It is tough to go against common beliefs. Kudos to you!

Warm wishes,

    I’m a Sierra Leonean and i think this myth is misunderstood. Actually, to us, it’s a superstitious belief that if a nursing mother has sex with another man who is not the baby’s father, then the baby will become very sick and probably die.

    I don’t believe in those superstitions and I think it’s just some forms of bad nursing associated with poor hygiene, unhealthy feeding and other causes of Sudden infant Death Syndromes(SIDS).

    We need proper pre and post natal education for parents of these categories.

    I wish all new mothers and expectant mothers the best.

    In South Africa too!

    Hi, guys in South Africa, most black people believe in that myth. It can happen to a child if u have sex with different men. Then the child can get sick. But it amazes me that white people can have sex with any man but their babies don’t get sick. What is wrong with ours or what is the fault with our breastmilk?

    Hi to you people is Sierra Leone (suckling mothers especially). I want you to know that the thinking that when you have sex whilst suckling your child will make the child sick is a myth. It is safe to have sex during the suckling period. This will cause no harm to your child.
    If you believe the myth above and start giving the baby other feeds; it is this feed that makes the baby sick because its system cannot tolerate it at this time.

    Feel free to have sex whilst breastfeeding your child.
