What Are Lion’s Mane Mushrooms?

Lion's mane mushrooms (Hericium erinaceus) are adaptogenic mushrooms that have been used for centuries in traditional Chinese medicine.

It is still one of the most popular and healthiest adaptogenic mushrooms due to its widespread availability and abundance of benefits. This fungus feeds on dead tree debris and prefers the temperate regions of Europe, northern Asia, andNorth America.

Take a look at our adaptogenic mushroom guide to learn more about how they function and the mechanics behind their therapeutic effects.

Side Effects of Lion’s Mane Mushrooms

There is no research or anecdotal evidence to show that eating lion's mane mushroom extract is harmful or dangerous.Hericium erinaceus has been used in traditional Chinese medicine for centuries and remains popular today, with the only recorded side effects of lion’s mane being an upset stomach and diarrhea upon first taking the mushroom.

Although these side effects are uncommon, you should begin with a low dose of the mushroom to avoid stomach troubles, especially if you've never used medicinal mushrooms before. Lion's mane can also have certain contraindications, such as allergies, and may interact with some medications. Read about potential lion’s mane drug interactions here.

Lion’s ManeMedicinal Mushrooms for Fertility

While there isn't much direct research on lion's mane's effects on fertility, there is evidence that its beneficial effects on hormone production could extend to fertility as well. These results are promising and certainly warrant further research on this topic, especially in humans.

Is Lion’s Mane Good for Hormones?

Lion's mane mushrooms can stabilize the production of sex hormones by stimulating nerve cell growth, particularly in the hypothalamus.

According to research, Hericium erinaceus appears to stimulate neurogenesis. Arecent Japanese study on the neurogenetic potential of lion's mane found that it can prompt nerve cell formation.

Lion's Mane regulates hormonal imbalance

Compounds in the lion's mane mushroom promote the production of brain-derived neurotrophic factors (BDNF) and nerve growth factors (NGF). In turn, BDNFs and NGFs influence hypothalamic hormone synthesis (growth hormone, vasopressin, adrenocorticotropic hormones, and sex hormones).

Sex hormones are “produced by the hypothalamic–pituitary–gonadal (HPG) axis,” according to one study. The effects of lion’s mane on hypothalamic hormone production could extend to testosterone production in men and estrogen production in women.

Lion’s Mane Benefits for Female Fertility

The benefits oflion’s mane mushrooms for women’s health and fertility have not been widely researched in humans. Still, existing research suggests a close connection between NGF and estrogen production:

Differential and reciprocal regulation of estrogen and nerve growth factor (NGF) receptor gene expression by their ligands suggests thatestrogen and the neurotrophins may influence each other's actions by regulating receptor/ligand availability or by reciprocal regulation at the level of gene transcription or signal transduction. (Toran-Allerand,et al.)

Due to the previously mentioned benefits of lion’s mane for NGF production, we can hypothesize that its benefits extend to estrogen production and fertility as well. Still, more human research is needed to fully uncover these mechanisms.

Lion’s ManeMale Fertility Benefits

There is no research on lion’s mane and male fertility, but available research suggests that NGF production may be connected to testosterone production and spermatogenesis, at least in animals.

2015 animal study on the topic concluded that “the present data suggest thatthe NGF system is involved in the testicular development and spermatogenesis of rabbits.” This study also associates NGF production with ovulation in female rabbits and adds that “NGF may act as a potential ovulation-inducing factor being abundantly present in the seminal plasma.”

To learn more about the effects of lion’s mane on male hormone production, read our article on lion’s mane and testosterone, as well as the one on lion’s mane and DHT production.

Is Lion’s Mane Safe During Pregnancy?

Anecdotal evidence and centuries of use suggest that it is safe to takelion’s mane while pregnant, though somepregnant women may choose not to take Hericium erinaceus or other medicinal mushrooms during pregnancy due to the lack of scientific research on the topic.

According to research, lion’s mane mushrooms appear tolower blood sugar levels, which could be beneficial for people withgestational diabetes. A 2020 study examined the effects of compounds found in thelion’s mane’s fruiting body on blood sugar.

The researchers conclude that the study “demonstrated the beneficial effect of H. erinaceus by characterization of α-glucosidase inhibitory compounds, including four new compounds. This approach can be valuable support for the traditional use of H. erinaceus for the treatment of diabetes and metabolic diseases, which needs to be clarified by further in-vivo study.”

To learn more about how you can benefit from lion’s mane while pregnant, take a look at our article on Hericium erinaceus and pregnancy. Or, read our blog post on lion’s mane and breastfeeding to learn about the safety of Hericium erinaceus for newborns.

What Is the Best Mushroom for Fertility?

Many medicinal mushrooms may have a beneficial impact on fertility due to theirhealth and wellness benefits.

For example,reishi mushrooms (Ganoderma lucidum), shiitake mushrooms (Grifola frondosa), maitake mushrooms (Grifola frondose), and turkey tail (Coriolus versicolor) all have antiinflammatory properties and reduce stress levels in the body, which can be incredibly beneficial for fertility.

However,studies have shown that cordyceps mushrooms have the most impressive benefits for fertility, both for men and for women. Let’s dive into those benefits:

Cordyceps for Female Fertility

If you want to increase yourchances of getting pregnant, Cordyceps sinensis is one of the best mushrooms you can consume. A study published by theInternational Journal of Biology of Reproduction examined the underlying mechanisms of how Cordyceps sinensis (CS) affects female sex hormone production.

They conducted experiments using different types of cells, such as rat Leydig cells and human granulosa lutein cells (GLCs) and discovered that CS can enhance the production of female sex hormones, particularly estrogen (E2), in GLCs.

Cordyceps influenced the activity of various enzymes involved in the production of these hormones. One important protein called StAR plays a role in transporting cholesterol, which is a necessary component for hormone production, into the mitochondria (an important structure in cells). The researchers found that CS increased the expression of StAR protein, leading to an increase in estrogen production.

This finding supports the idea that CS could have potential benefits in improving reproductive function in women. However, further research is needed to better understand the mechanisms of action involved in cordyceps-induced estrogen production and the effects of cordyceps mushrooms on pregnancy.

Cordyceps for Male Fertility

In addition to its beneficial effects on female fertility, Cordyceps sinensis seems to increase testosterone levels, which aids in male fertility. A clinical trial examined the in vivo and in vitro effects of thecordyceps mushroom on testosterone levels in mice.

The study found that testosterone levels increased significantly after cordyceps consumption and concluded that “it is possible that CS might contribute to an alternative medicine for the treatment of some reproductive problems caused by insufficient testosterone levels in human males.”
