Breastfeeding, hormones and desire

Many breastfeeding mothers notice that their interest in sex is much lower than before pregnancy, and that intercourse can feel uncomfortable. Husbands may notice it too and wonder what it means. In most cases it is not about the marriage at all. It is about hormones, healing and exhaustion, and it is usually temporary.

What the hormones are doing

Breastfeeding is driven by a hormone called prolactin, which supports milk production. While prolactin is high, estrogen tends to stay low. Lower estrogen is one reason many breastfeeding women have vaginal dryness and more delicate tissue, which can make intercourse uncomfortable. Oxytocin, released during feeding, brings closeness to the baby, and some mothers find that their need for touch is largely met by the end of the day. Many describe this as feeling touched out.

Add broken sleep, the physical work of feeding, and the mental load of caring for a newborn, and low desire is not surprising. These changes vary widely. Some women feel little difference, others feel a strong drop for many months. Desire often returns gradually as feeding becomes less frequent, cycles return and sleep improves, but there is no fixed timetable.
