1Male gametes are produced in the [blank_start]testes[blank_end] in structures called seminiferous tubules. From there, the sperm move into the [blank_start]epididymis[blank_end] where they become motile and are stored until sexual arousal causes them to move into the [blank_start]ductus deferens[blank_end]. A vasectomy involves litigating and cutting this structure, which prevents sperm from moving into the [blank_start]urethra[blank_end], which would carry the sperm out of the male body during ejaculation. If a male has not had a vasectomy, then during sex, sperm are ejaculated into the [blank_start]vagina[blank_end]. After this, they swim to the [blank_start]uterus[blank_end] and then are moved by contractions of the muscular wall of the female reproductive tract to the place where fertilization normally occurs. Female gametes are produced in the [blank_start]ovary[blank_end]. In response to changing hormone levels, an oocyte is ovulated and if all goes well, it gets drawn into the [blank_start]fallopian tube[blank_end]. Cilia lining the female reproductive tract move this oocyte (or developing embryo, if fertilization occurs) into the [blank_start]uterus[blank_end], where implantation should occur if the oocyte has been fertilized.
