Yes, human chorionic gonadotropin (hCG) can increase testicle size. hCG stimulates the testicles to produce testosterone, leading to increased testicular volume. Multiple studies support this.
Evidence from Research
Several studies demonstrate a significant increase in testicular volume following hCG treatment:
- Study 1: One study showed a mean testicular volume increase from 5.45 cc to 6.83 cc on the left side and 5.53 cc to 7.03 cc on the right side after hCG treatment (p<0.005). [Source needed - The provided text only mentions this result without a specific source.]
- Study 2: Another study reported a mean testicular volume increase from 5.5 ± 1.1 mL to 10.8 ± 1.6 mL during hCG treatment (P < 10-6). [Source: Gonadotropin therapy in men with isolated hypogonadotropic ...]
- Study 3: Research indicates that hCG treatment increases serum testosterone levels, penile length, and testicular volume in patients with hypogonadotropic hypogonadism (IHH). [Source: Penile Growth in Response to Human Chorionic Gonadotropin (hCG)...]
- Study 4: An open-label clinical trial demonstrated a significant increase in testicular volume with the combined use of corifollitropin alfa and hCG over 52 weeks. [Source: An open-label clinical trial to investigate the efficacy and safety of ...]
It's important to note that the rate at which testicular size increases with hCG varies between individuals. [Source: Targeting Micropenis, Supporting Fertility, and Increasing] The optimal hCG dosage for maximizing testicular stimulation is generally considered to be between 6000 and 10,000 IU.

While hCG can increase testicle size, it's crucial to remember that this effect is a consequence of increased testosterone production and not a direct result of hCG acting on testicular tissue independently. HCG's primary role is to stimulate the testicles to produce their own testosterone. [Sources: Several sources indirectly support this through the demonstrated increase in testosterone levels following hCG administration.] In cases where testicular shrinkage is a side effect of testosterone replacement therapy (TRT), hCG can be used to help maintain testicular size and function.
