31. Do not take laxatives for constipation; they can permanently impair gut motility . 32. Scleroderma can decrease motility anywhere in the gastrointestinal tract. 33. Nonoxynol-9 is the primary chemical in spermicides to inhibit sperm motility . 34. The resulting spermatozoa are now mature but lack motility , rendering them sterile. 35. While in the epididymis the spermatozoa gain motility and become capable of fertilization. 36. Because there is no motility , intestinal contents back up into the stomach. 37. This motility problem results from atrophy of the gastrointestinal tract wall smooth muscle. 38. Normal colonic motility requires integration of myogenic, neural, and hormonal influences. 39. The gastrointestinal tract generates motility using smooth muscle subunits linked by gap junctions. 40. And both implants produce superior motility and postoperative cosmesis.
