Many people notice the same pattern after sex:

l A sudden sense of calm

l Reduced desire

l Sleepiness or relaxation

This isn’t just psychological. It’s driven by a hormone called prolactin, which rises after orgasm.

What Is Prolactin?

Prolactin is a hormone produced by the pituitary gland. It plays a role in:

l Sexual satisfaction

l Recovery after orgasm

l Temporary reduction in sexual desire

In simple terms, prolactin signals to your body: “You’re done. Relax.”

How Orgasm Triggers Prolactin Release

During intercourse-induced orgasm:

1. Nerve signals build from stimulation

2. The brain processes these signals

3. A peak neural response occurs (orgasm)

4. The body releases prolactin

This process links the nervous system and endocrine system together.

 Orgasm is not just physical—it’s a neuro-hormonal event.

What Prolactin Does After Sex

After orgasm, prolactin:

l Reduces dopamine (pleasure drive)

l Creates a sense of satisfaction

l Promotes relaxation or sleep

This is why many people feel calm or tired after sex.

Why Some People Don’t Feel This Effect

Not everyone experiences this clearly. Common reasons include:

l No actual orgasm occurred

l Stimulation didn’t reach neural threshold

l Rhythm and timing were inconsistent

Key Takeaway

Orgasm is not about intensity alone. It’s about whether your body completes the full neural and hormonal response cycle.
