A step-by-step physiology explainer of male ejaculation. The video follows the emission and expulsion phases, the role of the prostate, seminal vesicles and pelvic muscles, and how the process is coordinated by the nervous system. Presented for anatomy and health education.

The largest amount of pus I have ever seen!!

Endotracheal intubation is demonstrated in close-up in this short clinical skills clip. The narration describes the hand positions used to open the mouth, insert the scope, visualize the vocal cords, and pass the tube. It is a training aid for airway management. The clip runs under a minute in total.

Tuberous breast deformity is a congenital breast anomaly that becomes manifest at the time of puberty and breast development. The three components of tubular deformity usually include, pseudoherniation of breast tissue into the nipple areolar complex, poorly defined inframammary fold and flattening of the lower pole of the breast which leads to a conical tubular shape.

This video shows the removal of an unusually long ingrown hair from the skin. An ingrown hair develops when a hair curls back and grows into the skin instead of outward, and the recording documents the extraction step by step. Ingrown hairs are a common minor skin complaint and can cause local irritation or inflammation.

Laparoscopic cornuotomy is
1. perfect for hemostasis
2. no adjuvant treatment
3. Probaility of preservation of cornua & tube
4. Possibility of vaginal delivery in Subsequent pregnancy

Autologous arteriovenous access is the key to long-term success with hemodialysis and is strongly supported by the National Kidney Foundation's Dialysis Outcomes Quality Initiative guidelines. Basilic vein transposition (BVT) fulfills the need for a durable conduit with high patency and maturation rates. This retrospective review examines a single group's experience with this procedure. All patients undergoing BVT for hemodialysis with available follow-up data were reviewed. Telephone interviews were used to supplement clinical data where needed. Functional assisted patency was used as the end point for this procedure, and if the access was never used for dialysis, then the patency was considered zero. Secondary interventions performed while the access remained patent and in use were not considered detrimental to the patency reported. One hundred seventy BVTs in 162 patients were performed between November 1992 and October 2001. There were 87 women (53.7%) and 112 black patients (69.1%); hypertension was present in 138 patients (85.2%) and diabetes in 89 patients (54.9%). Each year, an increasing incidence of BVT was performed in our dialysis population. The BVT was performed as the first access in that extremity in 73 of the procedures (42.9%). Functional patency (primary assisted) was achieved in 40.0% at 2 years and 15.2% at 5 years. The mean assisted patency was 14.6 months. To maintain BVT patency, 40 percutaneous secondary interventions (69.0%) and 18 surgical revisions (31.0%) occurred in 32 patients (19.0%). Ligation for swelling was necessary in 4 patients (2.5%), and steal syndrome occurred in 3 patients (1.9%). BVT is a useful autologous procedure for hemodialysis and the preferred access alternative in patients without an adequate cephalic vein. Although patencies remain poor relative to other conventional arterial vascular procedures, BVT is our most durable hemodialysis access procedure and is often the only available autologous conduit for hemodialysis.

Pregnancy ultrasounds are performed mainly using transabdominal ultrasound. For many women, especially after 8 weeks gestation, sufficient information about the baby may be obtained with transabdominal ultrasound only. However, in the early pregnancy, the developing embryo is very small (at 6 weeks gestation, the baby is only 5-9mm long) and a transvaginal ultrasound may be required to get a better image of the baby. Transvaginal ultrasound is safe and commonly performed during all stages of pregnancy, including the first trimester. It will not harm you or your baby.

Narrated by the operating surgeon, this clip shows fibroadenoma removal under local anaesthesia. A small subareolar incision is made, adhesions are freed along a dissection plane, and the whole fibroadenoma is delivered through the small opening. It is a short operative record in Surgery Videos.

Opening of the Cranium

A surgeon begins the PPH stapled hemorrhoidectomy by inserting a circular anal dilator and obturator into the anal canal and then securing the dilator in place with four sutures. The surgeon then inserts a PPH anoscope into the obturator. Next, he places a circumferential purse-string suture of 2-0 Monocryl on a UR-6 needle 4 cm proximal to the dentate line. The surgeon opens a PPH stapler and places its anvil across the purse string. The stapler is then closed and fired; it is held closed for two minutes to improve hemostasis. Prior to firing the stapler in a female patient, the surgeon places a gloved finger in the vagina to ensure the vaginal mucosa and rectal-vaginal septum are not trapped within the jaws of the closed stapler. The surgeon then opens and removes the stapler.

video shows how to insert a nasogatric tube.

By 5 weeks' gestational age, the wolffian (ie, mesonephric) and the müllerian (ie, paramesonephric) ducts have formed from intermediate mesoderm. In the absence of testosterone and müllerian inhibitory substance, the mesonephric ducts regress and the paramesonephric ducts continue to form the female reproductive structures with fusion of the distal portions of the paramesonephric ducts to give rise to the uterine fundus, the cervix, and the upper vagina. These developmental changes are genetically controlled in large part by a series of complex transcriptional signaling pathways including Wnt signaling, Hox genes, and many others. In a female fetus, the wolffian duct disappears except for nonfunctional vestiges. The müllerian duct is lined by a columnar epithelium. This includes the entire cervix and upper vagina to the vaginal plate (ie, sinovaginal bulb). Through a process of squamous metaplasia, the vagina and a variable portion of the ectocervix become covered with squamous epithelium. This process is complete by the fifth month of pregnancy.

A nursing demonstration in Dutch shows enema insertion as a medical procedure. The narration follows preparing the cannula, positioning the patient, inserting the cannula, letting fluid run in while checking comfort, and retaining it for about fifteen minutes. It closes with tidying, handwashing and reporting in Nursing Videos.

LCHI - Hernia repair done by medical students with guidance and assistance of Professor Luiz Eduardo C. Miranda. Description of surgery is in portuguese.

Surgical footage shows intestinal worms being removed from a young child during an operation. The recording comes from a pediatric surgical setting, with background speech in Thai. It is shared for education in pediatric surgery and parasitic disease. The recording runs about two and a half minutes in total.

What is the G spot? This explainer looks at the area of the anterior vaginal wall described by Dr Ernst Grafenberg, what anatomical studies have and have not established, and why researchers still debate whether it is a distinct structure. An educational overview of a genuinely unsettled question in sexual medicine.
