How does eating 12 eggs a day affect testosterone?

In this article, we will answer the question “How does eating 12 eggs a day affect testosterone?”, and what are the best testosterone-boosting foods.

How does eating 12 eggs a day affect testosterone?

Eggs have nutrients that affect testosterone. Eggs have many nutrients, important to testosterone production.

The consulted scientific literature did not present information that corroborates that the total of 12 eggs will bring a healthy increase in testosterone levels.

However, a 2021 study showed that consuming 3 whole eggs and a small percentage of other sources of cholesterol (842 mg/day of cholesterol, being 672 mg exclusively from eggs) increased testosterone levels by 2.4 ng/mL (1) because it is a precursor of steroid hormones, including estrogen, progesterone, and testosterone. Eggs contain about 200 mg of cholesterol (7).

Eggs have the nine essential amino acids (histidine; isoleucine; leucine; lysine; methionine; phenylalanine; threonine; tryptophan and valine) which are vital for the production of enzymes, and some hormones, such as testosterone (2,3).

The presence of albumin in the egg can increase testosterone levels, although the mechanism by which albumin may boost testosterone production is presently unknown (12).

Eggs also a source of fat-soluble vitamins; A, D, E, and K, and water-soluble B vitamins; thiamine (B1), riboflavin (B2), pantothenic acid (B5), pyridoxine (B6), biotin (B7), folate (B9), cobalamin (B12), and choline (2). Research indicates that vitamin D supplementation can increase testosterone levels in men (5,6).

Instead of focusing on a specific number of eggs, it’s crucial to incorporate eggs into a balanced diet that includes a variety of testosterone-boosting foods. 

Does eating eggs increase testosterone levels in women?

Yes, eating eggs increases testosterone levels in women.

Considering that cholesterol is one of the building blocks for testosterone production, it is assumed, therefore, that consumption of eggs (rich in cholesterol) will fatally increase the level of testosterone in both men and women (20).  However, the correlation of egg consumption in women is not clearly described in the consulted literature.

In women, testosterone is produced in much smaller amounts, primarily from the adrenal glands and the ovaries (20). Under normal circumstances, circulating T levels in men are 10–20 times higher than those in women (21). 

Testosterone, in women, plays an important role in female sexual desire, which leads women to use testosterone to increase libido. It is also used in postmenopausal women (21,22). This treatment has generally demonstrated efficacy for sexual desire, arousal, pleasure, responsiveness, and satisfaction. Treatment with testosterone is also used in female-to-male transsexuals (21).

Are there other foods capable of increasing testosterone?

Yes, there are many other foods capable of increasing testosterone.

Garlic, ginger, soybeans (isoflavones/lecithin), turmeric, emu oil, fish oil omega-3 and omega-6 polyunsaturated fatty acid, guarana (Paullinia cupana var. sorbilis), hazelnut, milk thistle seed and rosemary leaf, pepper, propolis, and royal jelly, Saccharomyces cerevisiae are some examples from other sources of substances that collaborate with the increase of testosterone levels (8).

Why is it important to pay attention to testosterone levels?

It is important to pay attention to testosterone levels because it is related to some diseases. Low testosterone levels in men are associated with hypogonadism, type 2 diabetes, and cardiovascular risk (9,10). In recent years, epidemiologic studies have suggested that obesity is associated with multiple alterations in the gonadal endocrine system and low testosterone levels (8). 

Furthermore, testosterone levels have been related to insulin resistance, as their decline occurs in parallel to an increase in HOMA-IR (11). 

For men wishing to optimize their testosterone levels, it may be wise to avoid a high fat intake, drink liquids such as water, or even consider fasting (12). 

Is there any risk of excessive egg consumption?

Yes, there are risks of excessive egg consumption.

The American Heart Association suggests one whole egg (or two egg whites) per day, as part of a healthy diet (13).

Allergic people to eggs, usually occurring soon after exposure can have some symptoms such as skin rashes and hives, digestion and its related problems, breathing problems, and anaphylaxis (14).

Until recently, a reduction in the consumption of eggs, a concentrated source of cholesterol, had been widely recommended to lower blood cholesterol and reduce the risk of heart disease. However, new studies have reported contradictory results on the association of egg consumption with cardiovascular disease due to its cholesterol content (15,16). However, as this association is still unclear, it is prudent to consider the consumption of eggs.

Consuming one or two eggs a day, when part of a low-fat diet, does not negatively affect the lipid profile and may even help improve vascular and intestinal function in individuals at low risk of developing cardiovascular disease and other metabolic disorders (17).

Although the egg has numerous health benefits, a balanced diet ensures the intake of the necessary nutrients, essential for maintaining health (18).

It is worth mentioning that the consumption of raw eggs, regardless of the quantity, must be careful, as they may contain Salmonella bacteria, responsible for intestinal infection (19).
