The FDA has approved the use of hCG injections for specific medical conditions. For individuals assigned female at birth (AFAB), these injections are used to treat fertility issues, while for those assigned male at birth (AMAB), they help manage certain types of hypogonadism.
Human chorionic gonadotropin (hCG) is commonly called “the pregnancy hormone” because of its essential role in maintaining pregnancy.
Pregnancy tests measure hCG levels in urine or blood to confirm pregnancy.

What is hCG used for in men?
Human Chorionic Gonadotropin (hCG) is a hormone naturally produced in the body, mainly by the placenta during pregnancy. However, its applications extend beyond pregnancy, particularly in men’s health. Below, we explore the various uses of hCG injections for men.
Testosterone Production and Fertility:
A primary use of hCG injections in men is to boost testosterone production. Testosterone is vital for male reproductive tissue development and maintaining secondary sexual characteristics. For men with hypogonadism (low testosterone levels), hCG injections can help increase testosterone.
Additionally, hCG injections can improve male fertility. When infertility stems from hormonal imbalances or sperm production issues, hCG can stimulate the testes to produce more sperm, which is particularly helpful for men undergoing assisted reproductive techniques like in vitro fertilization (IVF).
Weight Loss and Metabolism:
Recently, hCG injections have gained attention as a potential aid for weight loss and metabolism enhancement in men. The hCG diet, which combines a low-calorie diet with hCG injections, has been promoted as a way to promote rapid weight loss while preserving muscle mass.
The theory is that hCG suppresses appetite and promotes fat metabolism, leading to more efficient weight loss. However, scientific evidence supporting the hCG diet’s effectiveness is mixed, with some studies showing modest benefits and others finding no significant difference compared to a placebo.
Muscle Growth and Athletic Performance:
Some athletes and bodybuilders use hCG injections to enhance muscle growth and performance. It’s believed that hCG may have anabolic effects, stimulating muscle growth and strength when combined with resistance training.
However, using hCG for this purpose is controversial and carries risks and side effects. The World Anti-Doping Agency (WADA) has banned hCG in competitive sports due to its potential performance-enhancing effects.
Treatment of Hypogonadism:
Hypogonadism, characterized by low testosterone levels, can cause fatigue, reduced libido, and erectile dysfunction. When hypogonadism results from hypothalamus or pituitary gland dysfunction, hCG injections may be used as part of hormone replacement therapy to stimulate testosterone production.
By mimicking luteinizing hormone (LH), which stimulates testosterone production in the testes, hCG can help restore testosterone levels and alleviate hypogonadism symptoms.
In summary, hCG injections offer potential benefits for men, including increased testosterone, improved fertility, weight loss, and muscle growth. However, hCG should only be used under medical supervision, as misuse can cause adverse effects. More research is needed to fully understand hCG therapy’s long-term implications and efficacy for men’s health.
How does it work to increase testosterone?
Human Chorionic Gonadotropin (hCG) increases testosterone production by mimicking luteinizing hormone (LH), which the pituitary gland produces. LH regulates testosterone production in the testes.
Here’s how hCG stimulates testosterone:
1. Mimicking LH Action:
When injected, hCG binds to the same receptors in the testes’ Leydig cells as LH. This triggers biochemical reactions that increase testosterone synthesis.
2. Stimulation of Leydig Cells:
hCG binding to Leydig cells stimulates testosterone production, raising blood testosterone levels.
3. Maintenance of Testicular Function:
hCG helps maintain testicular function. For men with hypogonadism or impaired testicular function, hCG injections can preserve testicular size and support reproductive health.
4. Feedback Mechanisms:
Increased testosterone from hCG signals the hypothalamus and pituitary gland to reduce gonadotropin-releasing hormone (GnRH) and LH release, preventing excessive testosterone production.
5. Restoration of Normal Testosterone Levels:
For men with hypogonadism or low testosterone, hCG injections can restore normal levels, alleviating symptoms like fatigue, reduced libido, and erectile dysfunction.
Overall, hCG injections pharmacologically stimulate testosterone production in men with low levels. By mimicking LH and directly stimulating Leydig cells, hCG helps restore normal testosterone levels and supports reproductive health. hCG therapy should be administered under medical supervision for safety and efficacy.
What does the research say?
Research on Human Chorionic Gonadotropin (hCG) injections for men has yielded mixed results regarding testosterone production, fertility enhancement, weight loss, and muscle growth. Here’s an overview:
Testosterone Production and Hypogonadism:
Some studies suggest hCG therapy effectively increases testosterone and improves symptoms like fatigue and low libido in men with hypogonadism. However, long-term effects require further study.
Fertility Enhancement:
hCG injections show promise for improving male fertility, especially when infertility stems from hormonal imbalances or sperm production issues. hCG can stimulate sperm production, aiding conception, particularly with assisted reproductive techniques like IVF.
Weight Loss and Metabolism:
Evidence supporting the hCG diet for weight loss is mixed. Some studies report modest weight loss, while others find no significant difference compared to placebos. Very low-calorie diets with hCG raise safety concerns.
Muscle Growth and Athletic Performance:
Limited research exists on hCG for muscle growth. The World Anti-Doping Agency (WADA) bans hCG in sports due to potential performance-enhancing effects, but scientific support is lacking.
In conclusion, while hCG injections may benefit testosterone production and fertility, more research is needed on efficacy, safety, and side effects. Consult a healthcare professional before considering hCG therapy.
What are the side effects?
Human Chorionic Gonadotropin (hCG) injections can cause side effects. While many tolerate hCG well, potential risks include:
1. Injection Site Reactions:
Pain, redness, swelling, or irritation at the injection site are common side effects of hCG injections, typically mild and temporary.
2. Hormonal Imbalance:
hCG can cause hormonal imbalances, leading to mood swings, irritability, acne, or libido changes, especially with improper dosing.
3. Fluid Retention:
Some experience fluid retention or edema, causing swelling in hands, feet, or ankles. Severe cases may increase blood pressure or worsen cardiovascular conditions.
4. Gynecomastia:
hCG may cause gynecomastia (breast tissue development in men) due to hormonal imbalances. While usually reversible, it can cause distress.
5. Headaches and Fatigue:
Mild headaches or fatigue may occur but are typically temporary.
6. Ovarian Hyperstimulation Syndrome (OHSS):
Women undergoing fertility treatment with hCG injections risk OHSS, causing swollen, painful ovaries. Symptoms include bloating, nausea, vomiting, and breathing difficulties. Severe cases require hospitalization.
7. Blood Clots:
hCG therapy may theoretically increase blood clot risk, especially in those with cardiovascular risk factors or a history of clots. Watch for leg swelling, pain, or redness and seek medical attention if these occur.
Not everyone experiences these side effects, and severity varies by individual factors. Consult your healthcare provider if concerning symptoms arise during hCG therapy.
Can hCG be used for weight loss?
The use of Human Chorionic Gonadotropin (hCG) for weight loss is controversial. The hCG diet, combining a very low-calorie diet with hCG injections or supplements, gained popularity in the 1950s. However, scientific evidence supporting its effectiveness is mixed.
The Mechanism of Action:
Proponents claim hCG suppresses appetite and promotes fat metabolism, enabling rapid weight loss while preserving muscle. The hormone is thought to mobilize stored fat for energy and reduce hunger.
Research Findings:
Early studies suggested the hCG diet led to significant weight loss, but later research questioned its efficacy. A 2013 meta-analysis in the British Journal of Clinical Pharmacology found no scientific evidence supporting hCG for weight loss, attributing any results to severe calorie restriction.
Safety Concerns:
Very low-calorie diets with hCG raise safety concerns, including nutrient deficiencies, muscle loss, and metabolic imbalances. Long-term effects are unclear.
Regulatory Status:
The FDA has not approved hCG for weight loss. While hCG is approved for certain medical conditions, its off-label use for weight loss lacks scientific support.
Conclusion:
While some may experience short-term weight loss on the hCG diet, evidence is lacking. The severe calorie restriction poses health risks, and weight loss is likely regained. Sustainable approaches like balanced diets, regular exercise, and behavioral changes under medical guidance are recommended for weight loss.
