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.
An appendectomy (sometimes called appendisectomy or appendicectomy) is the surgical removal of the vermiform appendix. This procedure is normally performed as an emergency procedure, when the patient is suffering from acute appendicitis.
This narrated anatomy laboratory demonstration shows removal of the calvarium and brain in a cadaveric dissection. The instructor explains the saw cuts, separation of the dura, and identification of cranial nerves and dural venous sinuses as the dissection proceeds. It is a detailed study recording for neuroanatomy teaching.
You may have heard that some positions, such as your partner on top (missionary position), are better than others for getting pregnant. In fact, there's no evidence to back these theories up. Experts just haven't done the research yet. What experts have done, though, is use scanning to show what's going on inside when you're doing the deed. The research looked at two positions: the missionary position and doggy style. (Doggy style being when you're on all fours, and your partner enters you from behind). Common sense tells us that these positions allow for deep penetration. This means that they're more likely to place sperm right next to your cervix (the opening of your uterus). The scans confirm that the tip of the penis reaches the areas between the cervix and vaginal walls in both of these positions. The missionary position allows the penis to reach the area at the front of the cervix. The rear entry position reaches the area at back of the cervix. It's amazing what some experts spend their time doing, isn't it! Other positions, such as standing up, or woman on top, may be just as good for getting sperm right next to the cervix. We just don't know yet. http://www.babycentre.co.uk/sex-for-getting-pregnant#ixzz4XKnPLbxL
The menstrual cycle is the regular natural change that occurs in the female reproductive system like the uterus and ovaries that make pregnancy possible. The cycle is required for the production of ovocytes, and for the preparation of the uterus for pregnancy.
What Is It? Your wisdom teeth (third molars) usually start to erupt (enter your mouth) during the late teen years. Sometimes, there's not enough room for them. They may come into your mouth partially or not at all. Partial eruption of a wisdom tooth can create a flap of gum tissue next to the tooth. The flap can trap bits of food and debris. It can turn into a hotbed for bacteria. It's called pericoronitis if the tissue around the tooth becomes inflamed. Pericoronitis also can occur around a wisdom tooth that is still completely under the gums. Symptoms Symptoms include: Painful, swollen gum tissue in the area of the affected tooth. It can be difficult to bite down comfortably without catching the swollen tissue between your teeth. A bad smell or taste in the mouth Discharge of pus from the gum near the tooth More serious symptoms include: Swollen lymph nodes under your chin (the submandibular nodes) Muscle spasms in the jaw Swelling on the affected side of the face Diagnosis Usually, someone with pericoronitis goes to the dentist, complaining of pain in the area of the back tooth. Pericoronitis is diagnosed during the clinical exam. Your dentist will see inflamed gum tissue in the area of the unerupted or partly erupted wisdom tooth. The gums may be red, swollen or draining fluid or pus. Expected Duration Pericoronitis can be managed with antibiotics and warm salt water rinses. It goes away in about one week. However, it can return. This is likely to happen if the tooth does not completely enter the mouth and food and bacteria keep building up under the gum. Prevention You can help to prevent pericoronitis by brushing any erupting wisdom tooth and flossing around it. This will help make sure that food and bacteria do not build up under the gums. However, sometimes these steps do not work. If pericoronitis returns, you may need to have the flap of gum tissue removed. In some cases, the flap of tissue grows back and the wisdom tooth will need to be extracted. Treatment Pericoronitis can be tricky to treat. That's because the flap of gum tissue won't go away until the wisdom tooth emerges naturally, the tissue is removed or the tooth is removed. Your dentist will clean the area thoroughly by rinsing under the flap with water to remove bits of food and pus. Your dentist also may need to remove damaged tissue. If the area is infected, you'll most likely be given antibiotics. Your dentist will explain how to keep the area clean, which is the best way to prevent the problem from returning. This usually involves brushing and flossing daily and rinsing your mouth with water several times a day. These steps will help to prevent food from getting stuck under the gum flap. In some cases, your dentist may suggest removing the erupting tooth. Or the dentist may want to remove the tooth above it, which bites down on the gum below. If your dentist thinks the tooth may erupt fully into the mouth without problems, he or she may leave it alone. However, if pericoronitis comes back, the tooth may be extracted. Pericoronitis that causes symptoms should be treated as soon as possible. If it is not, the infection can spread to other areas of your mouth. The most severe cases are treated in a hospital. They sometimes require intravenous antibiotics and surgery. When To Call a Professional If you have symptoms of pericoronitis, make an appointment to see your dentist. If your wisdom teeth are coming in, visit your dentist at least twice a year for regular checkups. During those visits, the dentist can check on the progress of your wisdom teeth. Prognosis Pericoronitis does not cause any long-term effects. If the affected tooth is removed or erupts fully into the mouth, the condition cannot return.

Ejaculating into a partner’s mouth is a common practice during oral sex/fellatio. In a safe situation (where there is no danger of catching an STD), the semen-receiving partner may choose to spit the semen out, or to swallow it. Before you engage in fellatio, I’d recommend that you and your partner both get tested for sexually transmitted infections (STIs). If not, please use barriers for oral sex and abstaining from making contact with ejaculate. Semen is mostly water, but also contains amino acids and protein, sugars such as fructose and glucose, minerals such as zinc and calcium, vitamin C, and a few other nutrients. Sperm cells themselves make up less than one percent of semen. Semen is edible, and if swallowed, will travel down the esophagus and into the stomach, where it will be digested in the same way that food is. You can never get pregnant by swallowing semen. Some people accept the taste of semen, but others complain that swallowing semen can give them an upset stomach. In rare cases, you may have an allergy to the proteins found in semen. What does It Taste Like? The taste of semen varies. Bitter, sweet, metallic. So, one may expect to find the taste of semen anywhere from enjoyable to tasteless to disgusting. But there is a way of controlling the taste of semen, which is through diet. Keep track of the diet, and communicate with the partner about when it tastes better or worse.
The spleen is one of the most frequently injured intraperitoneal organs, and management of splenic injuries may require splenectomy .. The spleen is an wedge-shaped organ that lies in relation to the ninth and 11th ribs, located in the left hypochondrium and partly in the epigastrium; thus, it is situated between the fundus of the stomach and the diaphragm. The spleen is highly vascular and reddish purple; its size and weight are variable. A normal spleen is not palpable. The spleen's key function is the removal of old red blood cells "RBCs", defective circulating cells, and circulating bacteria. In addition, the spleen helps maintain normal erythrocyte morphology by processing immature erythrocytes, removing their nuclei, and changing the shape of the cellular membrane. Other functions of the spleen include the removal of nuclear remnants of RBCs, denatured hemoglobin, and iron granules ..
