The Male Fertility Factor You’re Probably Ignoring— Insulin Resistance
When couples struggle to conceive, the focus often lands on female hormones. But guys, you’re half the equation. And one surprising male fertility disruptor? Insulin resistance.
Here’s how insulin resistance can impact male fertility:
- Lower Testosterone: High insulin lowers testosterone, the hormone critical for sperm production.
- Sperm Production Drops: Low T means less sperm and poor motility (aka, slow swimmers).
- High Estrogen: Yes, men can make too much estrogen, especially when insulin is elevated. This further disrupts hormonal balance and sperm health (see above).
- DNA Fragmentation: Even if a semen analysis looks fine, sperm may still carry DNA damage linked to miscarriage and failed IVF cycles – something a standard test won’t show.
What to test:
- Fasted insulin + glucose
- Hemoglobin A1C
- Consider sperm DNA fragmentation testing if you’ve had miscarriages or low IVF fertilization rates
The good news? Insulin resistance is fixable with nutrition, movement, stress management, and evidence-backed supplements. We see this all the time inside the Fertility Confidence Method.
The key to supporting male (and female) fertility is to identify the root cause. Without that piece we’re just trying random internet strategies and hoping for the best.
But your body deserves better!
