RA-2 13-cis Retinoic Acid (Isotretinoin)

• Status: Completed
• Trial end date: 2018-12-01
• Target enrollment: 0
• Participant gender: Male

Summary

Men with infertility and normal hormone levels have few options for fertility treatment. Previous research work has suggested that men with infertility may have low levels of the active form of Vitamin A, called retinoic acid, in their testes. We think that giving men with low sperm counts retinoic acid may increase their sperm counts and improve their chances of fathering a pregnancy. We want to see if retinoic acid administration over twenty weeks can increase sperm production and help infertile men become fathers without the need for In vitro fertilization (IVF) and/or intracytoplasmic sperm injection (ICSI). We also want to see if adding calcitriol with retinoic acid will improve sperm motility in a sub-set of subjects.
