Does birth control affect milk supply?

Breastfeeding is a natural process that provides numerous benefits to both mother and child. However, many women wonder if using birth control methods can affect their milk supply. This concern has gained significance in recent years as more women are choosing to breastfeed while also desiring effective contraception.

The concept of using contraception to space pregnancies is not a new one. Throughout history, various methods have been employed to prevent unwanted pregnancies. In ancient times, women used natural methods such as herbal remedies or practices like breastfeeding on demand, as a way to protect themselves from conception. However, with the advent of modern medicine, hormonal contraceptives, such as birth control pills, patches, and injections, have become the go-to choice for many women due to their convenience and effectiveness.

It is estimated that nearly 50% of women in the United States use some form of hormonal birth control at some point in their lives. While these methods are known to be highly effective in preventing pregnancy, there have been concerns raised regarding their potential impact on breastfeeding and milk supply.

One compelling statistic indicates that hormonal contraceptives may have a slight effect on milk supply. Studies have shown that women who use hormonal birth control methods, such as the pill, may experience a slight decrease in their milk supply compared to those who do not use these methods. While the decrease is generally minimal and does not lead to complete cessation of breastfeeding, it is still a concern for many mothers who wish to provide their babies with an ample supply of milk.

However, it is important to note that not all women experience a decrease in milk supply while using hormonal contraceptives. Each woman’s body and response to these methods can vary. It is also worth mentioning that there are alternative non-hormonal birth control methods, such as barrier methods like condoms or copper IUDs, which do not have the same potential impact on milk supply.

For women concerned about the potential effects of hormonal birth control on their milk supply, working closely with a healthcare provider can help find a solution that meets their contraceptive needs while also ensuring adequate breastfeeding. Identifying the most suitable method, be it a non-hormonal option or carefully monitoring milk supply while using hormonal contraceptives, can help strike a balance between contraception and breastfeeding goals.

How Does Birth Control Affect Milk Supply?

In this article, we will explore the relationship between birth control methods and milk supply in breastfeeding mothers. By examining the effects of different contraceptive options on lactation, we aim to address the common concern of whether birth control can impact the quantity and quality of breast milk produced.

Stay tuned as we delve into the potential advantages or disadvantages of using certain types of birth control while breastfeeding, providing a comprehensive understanding of how these methods may affect milk supply. Let us now dive deeper into this topic and unravel the intricate relationship between birth control and lactation.

Does birth control affect milk supply?

One common concern for breastfeeding mothers is whether or not taking birth control can affect milk supply. It is important for women to understand the potential impact of birth control on lactation and make informed decisions about their reproductive health while breastfeeding.

Hormonal birth control and milk supply

Hormonal birth control methods, such as contraceptive pills, patches, and hormonal intrauterine devices (IUDs), contain synthetic hormones that can potentially affect milk supply. Estrogen and progestin, the primary hormones in most hormonal contraceptives, have been found to have varying effects on breastfeeding.

According to some studies, estrogen-containing birth control methods can reduce milk production in breastfeeding women. However, it is important to note that the estrogen doses found in most modern birth control pills are much lower than those used in the past, which may reduce the impact on milk supply. Progestin-only methods, such as the mini-pill or hormonal IUD, are generally considered safe for breastfeeding and are less likely to affect milk production.

Non-hormonal birth control options

For breastfeeding women concerned about the potential impact of hormonal birth control on milk supply, there are non-hormonal alternatives available. Barrier methods like condoms or diaphragms, as well as copper IUDs, can provide effective contraception without interfering with lactation. These methods do not contain hormones and are generally considered safe for breastfeeding mothers.

Consulting a healthcare provider

It is important for breastfeeding women to discuss their birth control options with a healthcare provider. They can provide personalized advice based on individual circumstances and medical history. Healthcare professionals can help weigh the benefits and potential risks of different contraceptive methods and guide women towards the most appropriate choice for their situation.

Women should inform their healthcare provider about their plans to breastfeed and any concerns they have about milk supply. This information can help the provider make informed recommendations and address any specific needs or preferences.


While the use of hormonal birth control may have the potential to affect milk supply in some women, it is not a universal outcome. Some women may experience a reduction in milk production, while others may not notice any difference. Non-hormonal birth control methods can be considered as alternatives for women concerned about their milk supply. Ultimately, the decision about birth control while breastfeeding should be made in consultation with a healthcare provider who can provide personalized guidance based on individual circumstances.

According to a study published in the Journal of Human Lactation, approximately 25% of breastfeeding women using hormonal birth control experienced a decrease in milk supply.

In conclusion, the article explored the question of whether birth control affects milk supply. Through a review of various studies and expert opinions, it was found that there is limited evidence to suggest that hormonal birth control methods can potentially decrease milk supply in some women.

It is recommended for women who are concerned about the potential impact on their milk supply to consult with their healthcare provider to find the most suitable birth control method that meets their needs. Overall, breastfeeding mothers can be reassured that hormonal contraception is generally safe to use without having a significant impact on their milk supply.
