Weight, hormones, and fertility: is there really a link?
This is a question many people have but few verbalize. It is a sensitive topic, touching on issues of body image, self-esteem, and health all at once. But discussing it clearly and without judgment is important.
What happens in the female body
Adipose tissue is not just an energy reserve — it is also an active endocrine organ. In excess, it produces oestrogens in a dysregulated manner and can cause insulin resistance. The result is a condition that directly affects the reproductive cycle.
Mechanisms involved
- 1Excess adipose tissue → excessive oestrogen production
- 2Insulin resistance → ovulatory dysfunction
- 3Hormonal imbalance → menstrual irregularities
- 4Increased risk of Polycystic Ovary Syndrome (PCOS)
The opposite is also true: a weight far below ideal (BMI under 18.5) can also suppress ovulation and cause menstrual irregularities, affecting fertility.
And in men? Male fertility is also affected
When it comes to fertility, men are often overlooked — but sperm quality accounts for half of the equation. In men with obesity, studies indicate an average 20% reduction in the couple's probability of conceiving.
"Sperm take about 3 months to complete their cycle — today's habits are reflected in tomorrow's sperm quality."
Impact on male fertility
- →Reduction in sperm quality and motility
- →Changes in hormonal balance (reduced testosterone)
- →Higher risk of poor embryonic development
- →Increased oxidative stress and sperm DNA damage
The role of supplementation in hormonal and reproductive support
Regardless of weight, cellular nutrition is a factor accessible to everyone. Certain nutrients play a direct role in hormonal support and protecting reproductive cells from oxidative stress.
