Oxytocin – The 'Love Hormone' That Triggers Labor
Did you know there is a hormone that can initiate labor, reduce pain, and simultaneously strengthen the bond between you and your child? The hormone is called oxytocin, often referred to as the 'love hormone,' and it plays a central role both during childbirth and in the first moments with your newborn.

What is Oxytocin?
Oxytocin is produced in the brain (in the hypothalamus) and is released into the bloodstream via the pituitary gland. The hormone is stimulated by physical touch, massage, and closeness, causing the entire body to respond with a positive 'feel-good' sensation. Stress levels decrease, pain feels less intense, and the bond between mother and child is strengthened.
Oxytocin During Childbirth
Oxytocin regulates labor and contributes to the initiation of childbirth. The hormone:
- Reduces fear and stress
- Helps you relax or even fall asleep during contractions
- Has anxiety-reducing and pain-relieving effects
After the baby is born, oxytocin helps the uterus contract, reduces the risk of bleeding, and strengthens the bond between mother and child.
Oxytocin During Breastfeeding
When the baby nurses or when breast pumping occurs, nerve impulses send signals to the pituitary gland to release oxytocin. This triggers the let-down reflex, allowing milk to flow to the baby.
Syntocinon – Synthetic Oxytocin
When necessary, doctors can use Syntocinon, a chemical variant of oxytocin, to initiate or enhance contractions. Unlike the body's own oxytocin, synthetic oxytocin does not affect emotions, bonding, or pain relief – it only has mechanical effects.
Important for Childbirth: Security
Oxytocin is blocked by stress and fear. Therefore, feeling secure is crucial. Create a list of things that make you feel calm:
- A secure environment during childbirth
- Soothing music
- Dim lighting (LED lights)
- Your own soft clothes
- A pillow or favorite blanket
- A meaningful photo
Feeling Secure with Staff and Support Persons
In addition to your partner, other support persons can accompany you during childbirth. Feeling secure with the midwife is crucial. If you have met the midwife beforehand or receive continuous support during childbirth, your sense of security increases, and the experience improves.
Tips:
- Speak up if something feels wrong
- Ask questions, preferably outside the delivery room to avoid stressing the birthing person
- Collaborate with the midwife for the best possible support
