Sperm cells must travel a long distance through the male and female reproductive systems in order to reach an egg to fertilize. Which organelle(s) would most help a sperm cell achieve this long journey?

Cervical and vaginal mucus, the cervix, "nooks" and "folds" in the uterine body, the uterotubal junction, the narrow fallopian tube, the corona radiata (granulosa cells surrounding and adhering to the oocyte following ovulation), the zona pellucida (the mucopolysaccharide layer separating the oocyte from the granulosa, ... Once the sperm have entered the uterus, contractions propel the sperm upward into the fallopian tubes. The first sperm enter the tubes minutes after ejaculation.
