When to stop

  • Breast tenderness or enlargement in men. That is a sign oestrogen has risen.
  • Severe abdominal pain, bloating, rapid weight gain or breathlessness after a fertility trigger. This can be ovarian hyperstimulation and needs urgent assessment.
  • Leg pain or swelling, chest pain or breathlessness. Clot symptoms.
  • Any allergic response: rash, hives, facial swelling or difficulty breathing. Seek urgent care.

Approved by the FDA and EMA as a prescription medicine for fertility and hypogonadism indications. Labelling is required to state that it is not effective for weight loss, and the FDA has acted against homeopathic hCG weight-loss products.
