Melatonin women hormones

Melatonin can significantly impact hormonal balance, particularly concerning estrogen and testosterone. It acts by inhibiting the gonadal axis, which reduces the output of these hormones from the ovaries and testes. This suppression can occur regardless of gender because both males and females produce estrogen and testosterone in different ratios and these hormones are essential for maintaining reproductive behaviors 1.

High levels of melatonin can also affect reproductive health, evidenced in seasonal breeding animals where elevated melatonin can lead to reduced testes and ovary size, causing infertility during specific seasons 2. Additionally, in children, melatonin plays a role in suppressing the onset of puberty, impacting other hormones crucial for development 3.

There is also a concern with supplementing melatonin, as the dosages in commercial supplements often exceed natural levels, which may inadvertently affect hormone systems beyond sleep, particularly the reproductive axis 4. It’s important to use melatonin cautiously, especially when considering its potential influence on these hormone systems.

For those considering melatonin supplementation, it’s crucial to work with a healthcare professional to understand the broader impacts, particularly relating to reproductive hormones 5.
