text: Yo, check it out, let me break it down for you real quick.
  Müllerian inhibiting substance, known as MIS,
  Produced by Sertoli cells, that's what the testes release.
  Now we're gonna see if it's in the seminal plasma,
  Using ELISA, we're about to make a blast, bruh!
  
  We took samples from 23 donors, all with normal sperm,
  And 169 patients, whose sperm wasn't quite firm.
  We checked the concentration, MIS levels in the fluid,
  Donors ranged from 0.5 to 3.6, patients from 0.5 to 17.8, they're more fluid.
  
  Now let's talk about sperm motility, that's the aim of our game,
  Patients had lower motility, it wasn't the same.
  The mean motility index was 113.3 for the patients, you see,
  While the donors scored 198.3, they were more free.
  
  But here's the twist, the MIS concentration was higher for the patients,
  Mean concentration for them was 4.2, for donors it's 1.4, no hesitations.
  We split the patients into two groups, I and II,
  Group I had motility below 50%, Group II was more like you.
  
  Group I had an MI of 62.3, that's low, my friend,
  Group II scored 130.2, they had more to defend.
  Both groups were significantly lower than the donors, no doubt,
  MIS concentrations were 5.4 and 3.9, that's what it's about.
  
  The relationship is inverse, as clear as day,
  MIS concentration and motility, they play.
  MIS might have a role in controlling the motion,
  That's what we're saying, that's the notion.
  
  So, there you have it, the study's findings are in,
  MIS in seminal plasma affects sperm's spin.
  It's all about the relationship, the connection they share,
  Now we gotta dig deeper, explore more, and dare.
