Millions of sperms are deposited into the vagina during sexual intercourse. The sperms make their way through the cervix into the uterus and then on to the fallopian tubes. As they swim along this way their numbers decline. Only a few hundred sperm will get close to the egg. During the trip, sperm prepare themselves to meet the egg by subtle alterations of their heads and movement patterns. Once inside the fallopian tube, the sperm attracts the egg by releasing a chemical. The egg is surrounded by a protective covering called the zona pellucida, which allows only one sperm to penetrate it. Once inside the egg, the head of the fertilizing sperm releases its genetic contents, which fuses with the nucleus of the egg. Fertilisation is now complete. Sperm are able to survive for 2-3 days within the female's reproductive tract. The length of the time that a woman's egg can be fertilized by a man's sperm ranges from 12-24 hours.
The fetal circulation is the circulatory system of a human fetus, often encompassing the entire fetoplacental circulation that also includes the umbilical cord and the blood vessels within the placenta that carry fetal blood.
The fetal circulation works differently from that of born humans, mainly because the lungs are not in use: the fetus obtains oxygen and nutrients from the mother through the placenta and the umbilical cord.
A penile prosthesis is another treatment option for men with erectile dysfunction. These devices are either malleable (bendable) or inflatable. The simplest type of prosthesis consists of a pair of malleable rods surgically implanted within the erection chambers of the penis. With this type of implant the penis is always semi-rigid and merely needs to be lifted or adjusted into the erect position to initiate sex. This type of implant is a good choice for men with spinal cord injuries and/or limited hand strength. Today, many men choose a hydraulic, inflatable prosthesis, which allows them to have an erection when they choose, and it's easier to conceal. It is also more natural. A penile implant is usually used when there is a clear medical cause for ED and when the problem is unlikely to resolve or improve naturally or with other medical treatments. Sometimes a penile prosthesis is implanted during surgery to reconstruct the penis when scarring has caused erections to curve (Peyronie's disease). Penile implant surgeries take about an hour and are typically done in an outpatient center. A man can resume sexual intercourse by 6 weeks after surgery.
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.
A gastroscopy is a procedure where a thin, flexible tube called an endoscope is used to look inside the oesophagus (gullet), stomach and first part of the small intestine (duodenum). It's also sometimes referred to as an upper gastrointestinal endoscopy. The endoscope has a light and a camera at one end.

A modified radical mastectomy is a procedure in which the entire breast is removed, including the skin, areola, nipple, and most axillary lymph nodes; the pectoralis major muscle is spared. Historically, a modified radical mastectomy was the primary method of treatment of breast cancer. [1, 2] As the treatment of breast cancer evolved, breast conservation has become more widely used. [3, 4] However, mastectomy still remains a viable option for women with breast cancer. [5, 6]
Your temporomandibular joint is a hinge that connects your jaw to the temporal bones of your skull, which are in front of each ear. It lets you move your jaw up and down and side to side, so you can talk, chew, and yawn. Problems with your jaw and the muscles in your face that control it are known as temporomandibular disorders (TMD). But you may hear it wrongly called TMJ, after the joint.
Hand hygiene for healthcare workers: Learn how to perform hand washing with soap and water (nursing procedures).
There are two ways to perform hand hygiene as a nurse. You can use soap and water or an alcohol-based hand rub (also called hand sanitizer or hand gel).
Hand hygiene is essential for providing safe patient care. If hand hygiene is not performed regularly, germs can be easily be spread to patients, other healthcare workers, and even yourself.
Hand hygiene is ALWAYS performed before and after patient care, after coming into contact with any type of body fluid or open wounds, when touching any object that is near a patient (hand railing, bedside table etc.), removing gloves, prior to eating, or after using the bathroom.
This video discusses when you should use soap and water versus an alcohol-based hand gel, when to perform hand hygiene, and demonstrates how to perform hand hygiene using soap and water.
