How to Optimize Fertility in Males & Females | Huberman Lab Podcast

Supplements

Nutritional supplements play a crucial role in enhancing fertility for both males and females. Andrew Huberman highlights the benefits of L-carnitine, which supports mitochondrial function essential for egg and sperm quality. He recommends taking 1 to 3 grams per day for at least 30 days before trying to conceive 1. Additionally, Shilajit is noted for its ability to increase testosterone and follicle-stimulating hormone, although women should consult their OB/GYN before use due to its impact on the ovulatory cycle 2.

L-carnitine is going to improve egg and sperm quality. And so you might actually take the stance that, even if you don't have any problem getting pregnant, wouldn't you want to maximize the quality of the egg that gets fertilized and the quality of the sperm that fertilizes that egg?

Huberman also advises pairing L-carnitine with garlic extract to offset potential side effects like increased TMAO levels 1.

   

Lifestyle

Lifestyle changes are essential for optimizing fertility. Andrew Huberman emphasizes the importance of keeping testicles cool to maximize sperm quality, advising against hot tubs, saunas, and placing laptops on laps 3. He also stresses the significance of quality sleep, which is fundamental for hormone balance and overall fertility. Six to eight hours of sleep per night is recommended to maintain optimal cortisol, testosterone, and estrogen levels 4.

Optimizing your sleep is fundamental to balancing your hormones.

Reducing time spent sitting and avoiding seat heaters can also help maintain the ideal temperature for sperm production 3.

   

Cold Exposure

Deliberate cold exposure can significantly enhance fertility by improving sperm quality and overall health. Andrew Huberman explains that cold exposure reduces excessive heat in the testicles, which is crucial for maintaining healthy sperm counts and quality 5. He mentions various methods, such as cold showers and ice baths, which can also boost dopamine and epinephrine levels, contributing to better psychological well-being 6.

Using deliberate cold exposure can be healthy for the sperm because of the ways not that cold directly supports testosterone or sperm quality but rather because cold reduces heat.

Huberman also notes that while there is less data on the effects of cold exposure on female fertility, the practice is generally beneficial for overall health 6.

   

Herbal Medicine

Herbal medicine, including acupuncture, offers promising benefits for fertility. Andrew Huberman discusses how acupuncture can improve semen volume, sperm quality, and motility in males, as well as regulate hormone levels in females 7. He emphasizes that acupuncture is no longer considered fringe science, with numerous clinical trials supporting its efficacy in enhancing fertility and pregnancy outcomes 8.

Acupuncture has been shown to improve semen volume, quality of sperm, sperm motility, et cetera.
