An egg cannot be fertilized when there are no sperm in the semen. The testicles continue to produce sperm, but the sperm are reabsorbed by the body. (This also happens to sperm that are not ejaculated after a while, regardless of whether you have had a vasectomy.) Sperm are made in the testicles. They pass through two tubes called the vasa deferentia to other glands and mix with seminal fluids to form semen. Vasectomy blocks each vas deferens and keeps sperm out of the seminal fluid. The sperm are absorbed by the body instead of being ejaculated.

Intramedullary nailing of the tibia with suprapatellar entry and semi-extended positioning makes it technically easier to nail the proximal and distal fractures. The purpose of this article was to describe a simple method for suprapatellar nailing (SPN). A step-by-step run through of the surgical technique is described, including positioning of the patient. There are as yet only a few clinical studies that illustrate the complications with this method, and there has been no increased frequency of intraarticular damage. Within the body of the manuscript, information is included about intraarticular damage and comments with references about anterior knee pain.

“Endo” is the Greek word for “inside” and “odont” is Greek for “tooth.” Endodontic treatment treats the inside of the tooth. Root canal treatment is one type of endodontic treatment. To understand endodontic treatment, it helps to know something about the anatomy of the tooth. Inside the tooth, under the white enamel and a hard layer called the dentin, is a soft tissue called the pulp. The pulp contains blood vessels, nerves, and connective tissue and creates the surrounding hard tissues of the tooth during development.
