Femstina Plus is NOT Approved or Indicated for Use in Men

Femstina Plus should not be used in men under any circumstances, as it contains ospemifene, a selective estrogen receptor modulator (SERM) specifically designed and FDA-approved only for postmenopausal women experiencing dyspareunia and vaginal atrophy. 1

Why This Medication is Contraindicated in Men

Mechanism and Intended Use

  • Ospemifene (the active ingredient in Femstina Plus) is a SERM that acts as an estrogen agonist on vaginal tissue, designed specifically to treat vaginal atrophy and painful intercourse in postmenopausal women 1
  • The medication has never been evaluated in men and carries unknown risks in the male population 1

Lack of Safety Data

  • There are no clinical trials, safety data, or efficacy studies evaluating ospemifene in men 1
  • The risk/benefit profile is completely unknown for male patients 1
  • Estrogen receptor modulation in men could potentially cause:
    • Gynecomastia (breast tissue development)
    • Suppression of testosterone production
    • Impaired spermatogenesis
    • Sexual dysfunction
    • Metabolic disturbances

What Men Should Use Instead for Sexual Health Issues

For Erectile Dysfunction

  • First-line treatment: PDE5 inhibitors (sildenafil, tadalafil, vardenafil, avanafil) are the standard of care for men with erectile dysfunction 1
  • These medications show 69% success rates for sexual intercourse attempts versus 33-35% for placebo 1
  • All four PDE5 inhibitors have similar efficacy in the general ED population 1

For Testosterone Deficiency

  • Men with confirmed hypogonadism and sexual dysfunction should receive testosterone therapy combined with PDE5 inhibitors for more severe ED 1
  • Testosterone therapy alone is not effective as monotherapy for ED 1

For Other Sexual Dysfunction

  • Vacuum erection devices (VED) show 90% initial efficacy 1
  • Intracavernosal injection therapy remains an option for PDE5i non-responders 1
  • Psychosocial interventions including cognitive behavioral therapy complement medical treatment effectively 1

Critical Safety Warning

Men should never take medications formulated for female reproductive health conditions. The hormonal effects of SERMs like ospemifene are fundamentally incompatible with male physiology and could cause significant harm. Any man experiencing sexual dysfunction should consult a urologist or men's health specialist for appropriate, evidence-based treatment options specifically studied and approved for male patients 1.
