Investigation and assisted reproduction in the treatment of male infertility

Fábio Firmbach Pasqualotto About the author

Male infertility affects 10% of couples in the reproductive age worldwide and is treatable in many cases. In addition to other well-described etiologies, genetic causes of male infertility are now more commonly diagnosed. In men with prior vasectomy or varicocele, microsurgical reconstruction of the reproductive tract or varicocelectomy is more cost-effective than sperm retrieval with in vitro fertilization and intracytoplasmic sperm injection if no female fertility risk factors are present. If epididymal obstruction after vasectomy is detected or advanced female age is present, the decision to use either microsurgical reconstruction or sperm retrieval with in vitro fertilization and intracytoplasmic sperm injection should be individualized. Sperm retrieval with in vitro fertilization and intracytoplasmic sperm injection is preferred to surgical treatment when female factors requiring in vitro fertilization are present or when the chance for success with sperm retrieval and intracytoplasmic sperm injection exceeds the chance for success with surgical treatment.
