  • To develop semen bank for donation purpose
  • To use it during the treatment if the male partner is unable to ejaculate on the stipulated day before undergoing vasectomy
  • Prior to cancer treatment which might adversely affect fertility
  • Surgically Retrieved sperm from epididymis (PESA) or testes (TESA)
