It is possible to lactate and breastfeed a baby without having given birth. This process, known as induced lactation, encourages the body to produce breast milk by mimicking the natural physiological signals of pregnancy and childbirth. This article explores how induced lactation is achieved and for whom this option is available.
Understanding Lactation
The human body’s ability to produce milk, known as lactation, is a complex process primarily regulated by hormones. During pregnancy, hormones like estrogen and progesterone prepare the mammary glands in the breasts for milk production. These hormones stimulate the growth of milk-making tissues, including the alveoli and milk ducts.
A different hormone, prolactin, is responsible for the actual production of milk in the alveoli. While prolactin levels rise during pregnancy, the high levels of estrogen and progesterone present at that time typically suppress its milk-producing action.
After birth, the sudden drop in estrogen and progesterone levels, following the delivery of the placenta, allows prolactin to trigger copious milk production. Oxytocin, another hormone, causes the small muscles around the milk-producing cells to contract, pushing milk through the ducts and out of the nipple, a process known as the “let-down” reflex. Ongoing milk production is sustained by frequent removal of milk through suckling or expression, which continues to stimulate prolactin and oxytocin release.
Induced Lactation: The Process
Induced lactation involves stimulating milk production in individuals who have not recently been pregnant or given birth.
The process often begins with hormonal medications. Estrogen and progesterone are administered for several months to mimic the hormonal environment of pregnancy, encouraging mammary tissue development.
Following this hormonal preparation, these medications are typically discontinued to simulate the hormonal drop after childbirth. Consistent breast stimulation then becomes crucial, often achieved through frequent pumping with a hospital-grade electric breast pump or manual expression. This signals the body to produce prolactin and oxytocin. Pumping sessions are generally frequent, often 8-12 times a day, including during the night, to establish and build a milk supply.
Healthcare providers may also prescribe galactagogues, medications that increase prolactin levels and milk supply. Examples include domperidone and metoclopramide, which influence dopamine receptors. Domperidone is not approved for use in the United States but is used in other countries. The process can take weeks to months to yield milk, with individual responses varying.
Who Can Induce Lactation
Induced lactation offers an opportunity for various individuals to experience breastfeeding, even without having carried a pregnancy.
This includes adoptive parents who wish to breastfeed their adopted child. It also extends to non-gestational parents in same-sex partnerships, allowing both partners to potentially share the feeding experience.
Individuals welcoming a baby via surrogacy may also choose induced lactation to provide breast milk and foster a close bond with their newborn.
Transgender women are another group who can successfully induce lactation, with several documented cases demonstrating this possibility. For these individuals, induced lactation can be a profoundly affirming experience.
Considerations for Induced Lactation
Embarking on induced lactation requires dedication and realistic expectations. The process demands a significant time commitment, particularly for consistent breast stimulation, which can span several months before milk production is fully established. While some individuals may achieve a full milk supply, the volume of milk produced is often less than after a biological birth, necessitating supplementation with formula or donor milk.
Professional support is important. Consulting with healthcare providers, such as physicians and lactation consultants, is highly recommended for personalized guidance, managing expectations, and monitoring well-being. They can help develop a tailored plan, which may include hormonal protocols or galactagogues, and offer strategies for effective milk expression.
Emotional and psychological support is valuable, as the journey can be demanding. Self-care and stress management contribute to the overall experience, as stress can impact milk production.
