To increase sperm count, the right medicine depends entirely on the underlying cause, which must be diagnosed by a doctor. If a hormone imbalance is responsible, treatments like Clomiphene, hCG, or gonadotropins may be prescribed. For infections, antibiotics are used. Additionally, daily supplements containing antioxidants like Zinc, Coenzyme Q10, Vitamin C, and L-carnitine can support sperm health. Please consult a urologist for a semen analysis before taking any medication. Avoid self-prescribing testosterone, as it can actually halt sperm production. Healthy lifestyle choices, like a balanced diet, regular exercise, and avoiding smoking, also play a vital role.
