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 vasectomy is procedure used to prevent a man from ejaculating sperm. There are two methods for performing this procedure. The |
|conventional vasectomy uses one or more small incisions in the scrotum used to access the vas deferens. They take a small section |
|out of both vas deferens and either tie or carterize the ends then stitch the cuts. The second way is called no-scalpel vasectomy |
|where a small hole is punctured in the scrotum in which the vas deferens is pulled out and severed then the vas deferens are tied |
|or catrtarized. No stitches are required since the holes are so small. The man will still function normally with discharge during |
|orgasm just no sperm will be ejaculated. |
2. Where does fertilization take place?
| |
|Fertilization takes place in the fallopian tubes. Once the sperm penetrates the egg the egg changes so no other sperm can enter. |
3. At what stage of fetal development does implantation take place?
|The egg remains in the tube for around 3 to 4 days when it journeys to the uterus where it will attach to the uterus wall. Some |
|spotting may occur during the time of implantation. During this
