Alpha blockers relax certain muscles and help small blood vessels remain open. They work by keeping the hormone norepinephrine (noradrenaline) from tightening the muscles in the walls of smaller arteries and veins, which causes the vessels to remain open and relaxed. This improves blood flow and lowers blood pressure.

ACE Inhibitor Mechanisms. Angiotensin converting enzyme (ACE) inhibitors are agents used to relax blood vessels and lower blood pressure. They prevent an enzyme from producing angiotensin II, which narrows blood vessels and raises blood pressure, meaning the heart has to work harder to pump blood around the body.

Loa loa filariasis (also known as loiasis, loaiasis, Calabar swellings, Fugitive swelling, Tropical swelling and African eyeworm) is a skin and eye disease caused by the nematode worm, loa loa. Humans contract this disease through the bite of a Deer fly or Mango fly (Chrysops spp), the vectors for Loa loa. The adult Loa loa filarial worm migrates throughout the subcutaneous tissues of humans, occasionally crossing into subconjunctival tissues of the eye where it can be easily observed. Loa loa does not normally affect one's vision but can be painful when moving about the eyeball or across the bridge of the nose.The disease can cause red itchy swellings below the skin called "Calabar swellings". The disease is treated with the drug diethylcarbamazine (DEC), and when appropriate, surgical methods may be employed to remove adult worms from the conjunctiva.

A spermatocele (SPUR-muh-toe-seel) is an abnormal sac (cyst) that develops in the epididymis โ€” the small, coiled tube located on the upper testicle that collects and transports sperm. Noncancerous and generally painless, a spermatocele usually is filled with milky or clear fluid that might contain sperm. The exact cause of spermatoceles is unknown but might be due to a blockage in one of the tubes that transports sperm. Spermatoceles, sometimes called spermatic cysts, are common. They typically don't reduce fertility or require treatment. If a spermatocele grows large enough to cause discomfort, your doctor might suggest surgery.

A lipoma is a growth of fat cells in a thin, fibrous capsule usually found just below the skin. Lipomas aren't cancer and don't turn into cancer. They are found most often on the torso, neck, upper thighs, upper arms, and armpits, but they can occur almost anywhere in the body. One or more lipomas may be present at the same time.

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. So, in the meantime, enjoy some variety in your sex life and keep it fun while you're trying for a baby. And talk to others who are hoping to get pregnant by joining our Actively trying group. Do I have to have an orgasm to conceive? Obviously, it's very important for your partner to reach orgasm if you are trying for a baby. There is no evidence, however, that you need to orgasm to conceive. The female orgasm is all about pleasure and satisfaction. It doesn't really help to get the sperm to the egg. Gentle contractions in your uterus can help the sperm along, but these happen without you having an orgasm. So, it's really not vital for you to reach orgasm after your partner, or even to reach orgasm at all, for you to conceive.

Emergency contraception is a method of birth control you can use if you had sex without using birth control or if your birth control method did not work correctly. You must use emergency contraception as soon as possible after unprotected sex. Emergency contraception pills are different from the abortion pill. If you are already pregnant, emergency contraception pills do not stop or harm your pregnancy. Emergency contraception has also been called the "morning-after pill," but you do not need to wait until the morning after unprotected sex to take it. Emergency contraception is not meant to be used for regular birth control. Talk to your doctor or nurse about regular birth control to help prevent pregnancy. Nearly half of all pregnancies in the United States are unplanned.1

A water birth means at least part of your labor, delivery, or both happen while youโ€™re in a birth pool filled with warm water. It can take place in a hospital, a birthing center, or at home. A doctor, nurse-midwife, or midwife helps you through it. In the U.S., some birthing centers and hospitals offer water births. Birthing centers are medical facilities that offer a more homelike setting than a hospital and more natural options for women having babies. The use of a birthing pool during the first stage of labor might: Help ease pain Keep you from needing anesthesia Speed up your labor The American College of Obstetricians and Gynecologists (ACOG), which sets guidelines for pregnancy and childbirth care in the U.S., says a water birth during the first stage of labor may have some benefits but delivering your baby underwater should be considered an experimental procedure with risks. The first stage is from when contractions start until your cervix is fully dilated.

In caring for patients who are critically ill, access to the central venous circulation is important. Central venous access allows the placement of various types of intravenous (IV) lines to facilitate the infusion of fluids, blood products, and drugs and to obtain blood for laboratory analysis. It is also an essential procedure in patients in whom placement of a line in a peripheral vein is impossible. A central line may be the only means of venous access in such cases.

The journey of egg and sperm. There are a lot of casualties (deaths) among the sperm as they swim toward the egg. First, many get lost in the maze of a woman's uterus where they also have to contend with acidic vaginal secretions.
