What Enclomiphene vs Clomiphene (Clomid) Treats

What it Treats

Both Enclomiphene and Clomiphene (Clomid) are used to address a variety of conditions related to testosterone levels and reproductive health. Here’s a breakdown of what each medication commonly treats.
Enclomiphene - What it Treats
  • Improves low testosterone levels in men
  • Supports symptoms of hypogonadism
  • Enhances energy and mood
  • Boosts libido and sexual function
  • Helps improve body composition and muscle mass
Clomiphene (Clomid) - What it Treats
  • Treats infertility in women by stimulating ovulation
  • Addresses low testosterone levels in men
  • Improves sperm count and motility in men with infertility issues
  • Supports symptoms of hypogonadism in men
  • Enhances overall reproductive health in both genders

How it Works

Enclomiphene and Clomiphene (Clomid) are selective estrogen receptor modulators (SERMs) that work by influencing hormone levels in the body, though they target different areas of treatment.
Enclomiphene - How it Works
Enclomiphene works by stimulating the body’s natural production of testosterone. It targets the hypothalamus and pituitary gland to increase the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which in turn boosts testosterone production. This mechanism helps improve symptoms of low testosterone, including fatigue, low libido, and mood issues.
Clomiphene (Clomid) - How it Works
Clomiphene works by blocking estrogen receptors in the hypothalamus, which signals the body to produce more gonadotropins (LH and FSH). In women, this promotes ovulation, while in men, it encourages increased sperm production and testosterone levels. By regulating these hormones, Clomiphene treats infertility and supports reproductive health.

Main Benefits

Both Enclomiphene and Clomiphene (Clomid) offer key benefits for patients dealing with hormonal imbalances and reproductive health concerns. Below are the specific medical conditions and symptoms each medication is designed to address.
Enclomiphene - Main Benefits

  • Alleviates symptoms of hypogonadism, such as fatigue and low energy
  • Improves sexual function by enhancing libido and erectile function
  • Boosts mood and mental clarity by increasing testosterone levels
  • Supports muscle mass and body composition by stimulating natural testosterone production
Clomiphene (Clomid) - Main Benefits
  • Stimulates ovulation in women with infertility issues
  • Improves sperm count and motility in men with low sperm production
  • Treats low testosterone levels in men, improving energy and sexual function
  • Regulates menstrual cycles in women with irregular periods due to hormonal imbalances
