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:
One 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—a condition marked by low testosterone—hCG injections can help increase testosterone levels.
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 beneficial 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 metabolic 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 behind the hCG diet is that the hormone 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, potentially stimulating muscle growth and increasing strength when combined with resistance training.
However, using hCG injections 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 symptoms like 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 production, improved fertility, weight loss, and muscle growth. However, hCG should only be used under medical supervision, as misuse can lead to adverse effects. Further 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 plays a key role in regulating testosterone production in the testes.
Here’s how hCG stimulates testosterone production:
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 cell receptors stimulates testosterone production, raising blood testosterone levels.
3. Maintenance of Testicular Function:
hCG helps maintain testicular function in men with hypogonadism or other conditions impairing testicular activity, supporting overall reproductive health.
4. Feedback Mechanisms:
Increased testosterone levels from hCG injections signal 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 testosterone 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 always be administered under medical supervision to ensure safety and efficacy.
What does the research say?
Research on Human Chorionic Gonadotropin (hCG) injections for men has yielded mixed results regarding their efficacy and safety for testosterone production, fertility enhancement, weight loss, and muscle growth. Here’s an overview of key findings:
Testosterone Production and Hypogonadism:
Studies suggest hCG therapy can effectively increase testosterone levels and improve symptoms of low testosterone, such as fatigue and reduced libido, in men with hypogonadism. However, long-term effects require further investigation.
Fertility Enhancement:
Research shows hCG injections can improve male fertility, especially when infertility stems from hormonal imbalances or sperm production issues. hCG stimulates sperm production, increasing conception chances, particularly with assisted reproductive techniques like IVF.
Weight Loss and Metabolism:
Evidence supporting the hCG diet for weight loss is inconsistent. Some studies report modest weight loss, while others find no significant difference compared to placebos. Very low-calorie diets combined with hCG raise safety concerns.
Muscle Growth and Athletic Performance:
Although some athletes use hCG injections to enhance muscle growth and performance, research is limited. WADA bans hCG in competitive sports due to potential performance-enhancing effects, but scientific support for its efficacy is lacking.
In conclusion, while hCG injections may benefit men by increasing testosterone and improving fertility, more research is needed on their efficacy, safety, and side effects. Individuals considering hCG therapy should consult a healthcare professional to weigh risks and benefits.
What are the side effects?
Human Chorionic Gonadotropin (hCG) injections can cause side effects, though many people tolerate them well. Potential side effects include:
1. Injection Site Reactions:
Common side effects of hCG injections include pain, redness, swelling, or irritation at the injection site. These are usually mild and temporary.
2. Hormonal Imbalance:
hCG can cause hormonal imbalances, especially if dosages are too high or unmonitored, leading to mood swings, irritability, acne, or libido changes.
3. Fluid Retention:
Some individuals experience fluid retention or edema, manifesting as swelling in hands, feet, or ankles. Severe cases may increase blood pressure or worsen cardiovascular conditions.
4. Gynecomastia:
hCG therapy may cause gynecomastia (breast tissue development in men) due to hormonal imbalances and increased estrogen levels. This is usually reversible but may require additional treatment.
5. Headaches and Fatigue:
Mild headaches or fatigue may occur, though these symptoms are typically temporary.
6. Ovarian Hyperstimulation Syndrome (OHSS):
Women undergoing fertility treatment with hCG injections risk OHSS, where ovaries become swollen and painful. Symptoms include abdominal bloating, nausea, vomiting, and breathing difficulties. Severe cases may require hospitalization.
7. Blood Clots:
There’s a theoretical risk of blood clots (thromboembolism) with hCG therapy, particularly in individuals with cardiovascular risk factors or a history of clots. Watch for swelling, pain, or redness in the legs and seek medical attention if these occur.
Not everyone experiences these side effects, and severity varies by individual factors like dosage, treatment duration, and underlying health conditions. Consult a 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 oral supplements, gained popularity in the 1950s but lacks strong scientific support.
The Mechanism of Action:
Proponents claim hCG suppresses appetite and promotes fat metabolism, enabling rapid weight loss while preserving muscle mass. The hormone is thought to mobilize stored fat for energy and reduce hunger, aiding adherence to strict calorie restrictions.
Research Findings:
Early studies suggested significant weight loss with the hCG diet, 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 rather than hCG itself.
Safety Concerns:
Very low-calorie diets combined with hCG injections can cause nutrient deficiencies, muscle loss, and metabolic imbalances. The long-term effects of hCG for weight loss remain unclear.
Regulatory Status:
The FDA has not approved hCG for weight loss. While hCG is approved for conditions like infertility, its off-label use for weight loss lacks scientific backing.
Conclusion:
While some may experience short-term weight loss on the hCG diet, evidence supporting its effectiveness and safety is insufficient. The extreme calorie restriction poses health risks, and weight loss is often regained
