Premature ejaculation occurs when a man ejaculates sooner during sexual intercourse than he or his partner would like. Premature ejaculation is a common sexual complaint. Estimates vary, but as many as 1 out of 3 men say they experience this problem at some time. As long as it happens infrequently, it's not cause for concern. However, you may meet the diagnostic criteria for premature ejaculation if you: Always or nearly always ejaculate within one minute of penetration Are unable to delay ejaculation during intercourse all or nearly all of the time Feel distressed and frustrated, and tend to avoid sexual intimacy as a result Both psychological and biological factors can play a role in premature ejaculation. Although many men feel embarrassed to talk about it, premature ejaculation is a common and treatable condition. Medications, counseling and sexual techniques that delay ejaculation — or a combination of these — can help improve sex for you and your partner.
Epley maneuver: Step 1 You will sit on the doctor's exam table with your legs extended in front of you. The doctor will turn your head so that it is halfway between looking straight ahead and looking directly to the side that causes the worst vertigo. Without changing your head position, the doctor will guide you back quickly so that your shoulders are on the table but your head is hanging over the edge of the table. In this position, the side of your head that is causing the worst vertigo is facing the floor. The doctor will hold you in this position for 30 seconds or until your vertigo stops. Epley maneuver: Step 2 Then, without lifting up your head, the doctor will turn your head to look at the same angle to the opposite side, so that the other side of your head is now facing the floor. The doctor will hold you in this position for 30 seconds or until your vertigo stops. Epley maneuver: Step 3 The doctor will help you roll in the same direction you are facing so that you are now lying on your side. (For example, if you are looking to your right, you will roll onto your right side.) The side that causes the worst vertigo should be facing up. The doctor will hold you in this position for another 30 seconds or until your vertigo stops. Epley maneuver: Step 4 The doctor will then help you to sit back up with your legs hanging off the table on the same side that you were facing. This maneuver is done with the assistance of a doctor or physical therapist. A single 10- to 15-minute session usually is all that is needed. When your head is firmly moved into different positions, the crystal debris (canaliths) causing vertigo will move freely and no longer cause symptoms.
Benign paroxysmal positional vertigo (BPPV) is one of the most common causes of vertigo — the sudden sensation that you're spinning or that the inside of your head is spinning. Benign paroxysmal positional vertigo causes brief episodes of mild to intense dizziness. Benign paroxysmal positional vertigo is usually triggered by specific changes in the position of your head. This might occur when you tip your head up or down, when you lie down, or when you turn over or sit up in bed. Although benign paroxysmal positional vertigo can be a bothersome problem, it's rarely serious except when it increases the chance of falls. You can receive effective treatment for benign paroxysmal positional vertigo during a doctor's office visit
Urinary incontinence — the loss of bladder control — is a common and often embarrassing problem. The severity ranges from occasionally leaking urine when you cough or sneeze to having an urge to urinate that's so sudden and strong you don't get to a toilet in time. If urinary incontinence affects your daily activities, don't hesitate to see your doctor. For most people, simple lifestyle changes or medical treatment can ease discomfort or stop urinary incontinence
Traumatic penile injury can be due to multiple factors. Penile fracture, penile amputation, penetrating penile injuries, and penile soft tissue injuries are considered urologic emergencies and typically require surgical intervention. The goals of treatment for penile trauma are universal: preservation of penile length, erectile function, and maintenance of the ability to void while standing. Traumatic injury to the penis may concomitantly involve the urethra.[1, 2] Urethral injury and repair is beyond the scope of this article but details can be found in Urethral Trauma. Penile fracture Penile fracture is the traumatic rupture of the corpus cavernosum. Traumatic rupture of the penis is relatively uncommon and is considered a urologic emergency.[3] Sudden blunt trauma or abrupt lateral bending of the penis in an erect state can break the markedly thinned and stiff tunica albuginea, resulting in a fractured penis. One or both corpora may be involved, and concomitant injury to the penile urethra may occur. Urethral trauma is more common when both corpora cavernosa are injured.[4] Penile rupture can usually be diagnosed based solely on history and physical examination findings; however, in equivocal cases, diagnostic cavernosography or MRI should be performed. Concomitant urethral injury must be considered; therefore, preoperative retrograde urethrographic studies should generally be performed. See the images below.
An undescended testicle (cryptorchidism) is a testicle that hasn't moved into its proper position in the bag of skin hanging below the penis (scrotum) before birth. Usually just one testicle is affected, but about 10 percent of the time both testicles are undescended. An undescended testicle is uncommon in general, but common among baby boys born prematurely. The vast majority of the time, the undescended testicle moves into the proper position on its own, within the first few months of life. If your son has an undescended testicle that doesn't correct itself, surgery can relocate the testicle into the scrotum.
Conversion disorder, also called functional neurological symptom disorder, is a condition in which you show psychological stress in physical ways. The condition was so named to describe a health problem that starts as a mental or emotional crisis — a scary or stressful incident of some kind — and converts to a physical problem.
A kidney stone may not cause symptoms until it moves around within your kidney or passes into your ureter — the tube connecting the kidney and bladder. At that point, you may experience these signs and symptoms: Severe pain in the side and back, below the ribs Pain that spreads to the lower abdomen and groin Pain that comes in waves and fluctuates in intensity Pain on urination Pink, red or brown urine Cloudy or foul-smelling urine Nausea and vomiting Persistent need to urinate Urinating more often than usual Fever and chills if an infection is present Urinating small amounts of urine Pain caused by a kidney stone may change — for instance, shifting to a different location or increasing in intensity — as the stone moves through your urinary tract.
A Pap smear (also called a Pap test) is a screening procedure for cervical cancer. It tests for the presence of precancerous or cancerous cells on the cervix, the opening of the uterus. It's named after the doctor who determined that this was a useful way to detect signs of cervical cancer.
Cluster headaches, occur in cyclical patterns or clusters, are one of the most painful types of headache. A cluster headache commonly awakens you in the middle of the night with intense pain in or around one eye on one side of your head. Bouts of frequent attacks, known as cluster periods, can last from weeks to months, usually followed by remission periods when the headaches stop. During remission, no headaches occur for months and sometimes even years. Fortunately, cluster headache is rare and not life-threatening. Treatments can make cluster headache attacks shorter and less severe. In addition, medications can reduce the number of cluster headaches.
Rotationplasty is a type of autograft wherein a portion of a limb is removed, while the remaining limb below the involved portion is rotated and reattached. This procedure is used when a portion of an extremity is injured or involved with a disease, such as cancer. Typically, the ankle joint becomes the knee joint.
Sciatica is often characterized by one or more of the following symptoms: Constant pain in only one side of the buttock or leg (rarely in both legs) Pain that is worse when sitting Leg pain that is often described as burning, tingling, or searing (versus a dull ache) Weakness, numbness, or difficulty moving the leg, foot, and/or toes A sharp pain that may make it difficult to stand up or walk Pain that radiates down the leg and possibly into the foot and toes (it rarely occurs only in the foot) Sciatica Causes and Treatments Video Watch: Sciatica Causes and Treatments Video Sciatic pain can vary from infrequent and irritating to constant and incapacitating. Symptoms are usually based on the location of the pinched nerve. While symptoms can be painful and potentially debilitating, it is rare that permanent sciatic nerve damage (tissue damage) will result, and spinal cord involvement is possible but rare.
Take your left leg and place your ankle against the knee. Hold the position for a moment before changing legs. This helps stretch the tiny piriformis muscle, which sometimes becomes inflamed and presses against the sciatic nerve causing pain. Repeat by switching sides and doing the same exercise with the other leg.
Vaginal childbirth, including labor and delivery, is recorded in this obstetrics video. The footage presents the process of a baby being born through the birth canal in a clinical setting. It is an educational resource for students and caregivers learning about normal vaginal delivery.
The Epley Maneuver for Vertigo can be very effective at relieving vertigo symptoms, but it’s a procedure that should be performed by a physical therapist or other health care professional. This video is for demonstration purposes only. See Doctor Jo’s blog post about the Epley
