text: Yo, listen up, I'm 'bout to drop some knowledge,
  'Bout inhibin B and how it affects your system,
  Sertoli cells be producin' that hormone,
  Givin' negative feedback, keepin' FSH in the zone.
  
  In men, inhibin B, that's the real deal,
  The form of inhibin that they gotta feel,
  We measured serum inhibin B in this study,
  Checkin' out the fellas, makin' things less muddy.
  
  Forty normal men, average age of twenty-seven,
  Sperm concentrations, a hundred mill' per mL, no leaven,
  Then fifty-one subfertile men, thirty-one years old,
  Sperm concentrations, six-point-eight, it's told.
  
  Sixteen men with varicocele in the mix,
  Sperm concentrations, fifty-four-point-three, no tricks,
  Men with hypogonadotrophic hypogonadism too,
  Klinefelter syndrome, azoospermia, we seein' through.
  
  In men with sperm concentrations above twenty mill',
  Serum inhibin B was two-hundred-one, that's a thrill,
  FSH levels at four, keepin' things in check,
  That's the deal for the dudes, no room to flex.
  
  Varicocele patients, they show the same,
  Normal sperm concentrations, inhibin B ain't to blame,
  One-seventy-three, that's the level they see,
  FSH levels normal, no worries, it's a spree.
  
  But for patients with sperm concentrations too low,
  Inhibin B levels, one-eighteen, it's a blow,
  FSH levels at ten, that's a higher rate,
  That's the situation, no time to debate.
  
  Now, in all patients studied, 'cept a few,
  Inhibin B and FSH, they had a clue,
  They were inversely correlated, that's for sure,
  Negative point-four-one, p-value above the floor.
  
  There's a positive correlation with sperm concentrations,
  Inhibin B and the fellas, they got relations,
  Positive point-three-four, p-value on the low,
  That's what the data's showin', it's time to go.
  
  In varicocele men, the correlation's strong,
  Point-five-seven-four, p-value singin' its song,
  Inhibin B might be a marker, testicular function,
  Diagnosin' dysfunctions, that's the junction.
  
  So there you have it, the facts are laid out,
  Inhibin B, FSH, what it's all about,
  Now you know the deal, the science is clear,
  Inhibin B keeps things in balance, no fear.
