title: Possible role of pure human follicle-stimulating hormone in the treatment of severe male-factor infertility by assisted reproduction: preliminary report.
abstract: OBJECTIVE
  Experimental clinical trial assessing the potential of systemic follicle-stimulating hormone (FSH) to improve sperm fertilizing ability in in vitro fertilization (IVF).
  
  
  METHODS
  Retrospective clinical evaluation of severe male factor patients failing fertilization in IVF or showing severe sperm defects.
  
  
  METHODS
  Academic tertiary clinical care unit.
  
  
  METHODS
  Fourteen patients (41 cycles) who failed IVF, 22 patients (32 cycles) with severe quantitative and qualitative semen abnormalities indicating poor fertilization.
  
  
  METHODS
  
  
  
  METHODS
  FSH 150 U IM three times a week for 3 months.
  
  
  METHODS
  Pretreatment and post-treatment evaluation of endocrine profile, basic semen analysis, and fertilization and pregnancy rates.
  
  
  OBJECTIVE
  FSH treatment may improve spermatogenesis quality by its multiple actions on the Sertoli-gamete cell compartment without interfering with testicular hormonogenic function.
  
  
  RESULTS
  No significant changes were observed in the endocrine profile or in semen parameters; individual cases showed improvements in sperm concentration and motility. Significant increase in fertilization rate of preovulatory oocytes was demonstrated; seven term pregnancies were achieved.
  
  
  CONCLUSIONS
  A multicenter randomized, double-blind trial with crossover is needed to demonstrate the benefit of systemic FSH administration and if this effect is FSH exclusive.
