The correct option is A vas deferens; fallopian tubes
∙ Vasectomy and tubectomy are two permanent surgical method of contraception in male and female, respectively.
∙ In vasectomy, a small portion of vas deferens (sperm ducts) is removed by surgical operation and both ends are tied properly so as to avoid the passage of sperms. This method is called vasectomy.
∙ In tubectomy, a small portion of oviducts (fallopian tube) is removed by surgical operation in female and the cut ends are tied to prevent the entry of ovum into the oviducts. This method is called tubectomy.
Thus, these techniques prevent fertilization and hence unwanted pregnancies.
