I barely purchesed this item for my husband. He's been taking them as well as the fertilaid for the better part of a Month already. He complains about the smell from this particular product (motilityboost) They do smell horrid! For lack of better words, it smells like a rooten Fart. He is a bit more, um ready? We were told we could only get pregnant by a IUI or Invito, due to his extremley low sprem count as well as poor progression (The way they move) I really hope this works!! Most sites say it takes about 6 months so I will re-post if it works for us! P.S He also has alot of gas, burps and farts alot more :)
