a. Ectopic Pregnancy

Answer the following questions

1. How is a vasectomy performed? Be sure to cite the specific anatomical structures involved. How does this prevent pregnancy?

| |

|A small incision is made in the scrotum and each vas deferens is tied up and cut apart preventing sperm from being release within |

|the ejaculate. The small skin incision stitch close and the surgery do not affect a man sexual function. So disconnecting this tube|

|and tying of the free ends blocks this pathway and sperms are prevented from reaching the urethra. So no sperms; no pregnancy |

2. Where does fertilization take place?

|Fertilization takes place in the fallopian tube, more specifically the juncture of the ampulla and isthmus (ampullary-isthmic |

|junction). |

3. At what stage of fetal development does implantation take place?

|During the fourth week implantation of fetal development takes place. At this stage the fertilized egg is now called a blastocyst. |

4. What is an ectopic pregnancy?

|In an ectopic pregnancy, a fertilized egg has implanted outside the uterus, usually in the fallopian tubes. That means the egg is |

|out of place. |

5. Distinguish between an identical and non-identical twins. Do all identical twins develop the same way?

|Identical twins...
