Key differences
Clomiphene belongs to Hormones and Birth Control while Viagra belongs to Erectile Dysfunction (ED). Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action
Clomiphene: Clomiphene blocks estrogen receptors at the hypothalamus, preventing the negative feedback that estrogen normally exerts on gonadotropin-releasing hormone production. Viagra: During sexual stimulation, nitric oxide is released in the corpus cavernosum and activates an enzyme that produces cyclic GMP.
When Clomiphene is preferred
Clomiphene is indicated for ovulation induction in women with anovulatory infertility and intact pituitary-ovarian axis function, when other causes of infertility have been excluded or are being addressed.
When Viagra is preferred
The medication is indicated in adult men for the treatment of erectile dysfunction, defined as the inability to achieve or maintain a penile erection sufficient for sexual activity.
