Male Reproductive Anatomy Male Reproductive Anatomy Words To Know: Testosterone: Male hormone. Causes hair growth, deeper voice, sperm production. Bladder: Organ that holds urine until excreted from the body. Testicle / Testes: Male organ that produces the sperm. 100 million sperm produced a day. The testes are developed high in the body and nerve endings are still there. Sperm Cells: Male reproductive cell produced in the testes. Scrotum: This is a sac that regulates the temperature of the testes. Keeps temperature at 95℉ and will rise closer to the body (to get warmer, use body heat) and lower (cool down) to help with this. Epididymis: Sperm is stored here. Can hold sperm for 6 weeks or until mature. Vas Deferens: A tube that travels from the epididymis to the urethra. Sperm travel along this tube. Seminal Vesicle: This vesicle adds a sugary fluid to the semen. Prostate Gland: This gland adds a chemical fluid to the semen. Cowper’s Gland: Secretes a fluid that helps make the environment safer for the sperm. Urethra: Brings urine and semen out of the body. Penis: Is made up of a spongy tissue. Erection: When the penis becomes engorged with blood and hard. Semen: Fluid ejaculated from the penis. Six Ways to Care for the Male Reproductive System! 1. Choose Abstinence. Abstinence is choosing not to be sexually active. Choosing abstinence prevents infection with sexually transmitted diseases. It also keeps you from becoming a teen father. 2. Have Regular Medical Checkups. Your physician can examine you and discuss body changes. 3. Bathe or Shower Daily. Keep your external reproductive organs clean. 4. Wear Protective Clothing and Equipment when Playing Sports. Some shorts contain an athletic supporter that provides support for the penis and scrotum. Protective equipment, such as a cup, helps prevent injury to these organs. 5. Perform Regular Testicular Examinations. Check for lumps and changes. This is important habit to develop now and practice for a lifetime. Discuss any Concerns you have with your Parents or Guardian. You might have questions about body changes or erections. Discuss your concerns with your parents or guardian. .

It is part of the digestive system; it gets rid of body wastes. Buttocks – The medical word for a person’s “bottom” or “rear end.” Cervix – The opening of the uterus into the vagina. Circumcision – An operation to remove the foreskin from the penis. Cowper’s Glands – Glands on either side of the urethra that make a discharge which lines the urethra when a man gets an erection, making it less acid-like to protect the sperm. Clitoris – The part of the female genitals that’s full of nerves and becomes erect. It has a glans and a shaft like the penis, but only its glans is on the out side of the body, and it’s much smaller. Discharge – Liquid. Urine and semen are kinds of discharge, but the word is usually used to describe either the normal wetness of the vagina or the abnormal wetness that may come from an infection in the penis or vagina. Duct – Tube, the fallopian tubes may be called oviducts, because they are the path for an ovum.

This miracle is a characteristic that all living things have in common and sets them apart from nonliving things. But even though the reproductive system is essential to keeping a species alive, it is not essential to keeping an individual alive. In human reproduction, two kinds of sex cells or gametes are involved. Sperm, the male gamete, and an egg or ovum, the female gamete must meet in the female reproductive system to create a new individual. For reproduction to occur, both the female and male reproductive systems are essential. While both the female and male reproductive systems are involved with producing, nourishing and transporting either the egg or sperm, they are different in shape and structure. The male has reproductive organs, or genitals, that are both inside and outside the pelvis, while the female has reproductive organs entirely within the pelvis. The male reproductive system consists of the testes and a series of ducts and glands. Sperm are produced in the testes and are transported through the reproductive ducts. These ducts include the epididymis, ductus deferens, ejaculatory duct and urethra. The reproductive glands produce secretions that become part of semen, the fluid that is ejaculated from the urethra. These glands include the seminal vesicles, prostate gland, and bulbourethral glands.

Herein, we extend our knowledge by describing formation of the Urethra human urethra within the glans penis as well as development of the prepuce. Forty-eight normal human fetal Human penile specimens were examined using scanning electron microscopy and optical projection tomography. Serial Glans histologic sections were evaluated for morphology and immunohistochemical localization for epithelial differ- Prepuce Canalization entiation markers: Cytokeratins 6, 7, 10, FoxA1, uroplakin and the androgen receptor. As the closing zipper completes fusion of the urethral folds within the penile shaft to form a tubular urethra (~ 13 weeks), canali- zation of the urethral plate continues in proximal to distal fashion into the glans penis to directly form the urethra within the glans without forming an open urethral groove. Initially, the urethral plate is attached ventrally to the epidermis via an epithelial seam, which is remodeled and eliminated, thus establishing me- senchymal confluence ventral to the glanular urethra. The morphogenetic remodeling involves the strategic expression of cytokeratin 7, FoxA1 and uroplakin in endodermal epithelial cells as the tubular glanular urethra forms.

Hospital Universitario San Carlos. Universidad Complutense de Madrid La primera descripción de una torsión o vólvulo del cordón espermático parece que fue realizada por Delasiauve’, en el año 1840, bajo el siguiente epígrafe: «Necrosis de un testiculo ectópico ocasionado por una hernia inguinal estrangulada en el adulto». La torsión del cordón espermático con la consecuente isquemia e infarto hemorrágico del parénquima testicular constituye uno de los accidentesvasculares dídimo epididimarios más importantes y que, a pesar del aumento progresivo de su incidencia anual, obliga a la orquiectomia tanto o más que ninguna otra patología testicular, incluido lostumores de dicho órgano’3. Según se desprende de la literatura médica revisada, al igual que de nuestra propia experiencia, será difícil que disminuya ostensiblemente el número de exéresis testiculares por esta causa patológica en un futuro próximo, aun contando en el mayorde loscasos con la colaboración del paciente, nuevas técnicas para un diagnóstico precoz y una actuación de urgencia quirúrgica4- <‘L É2AÑ¡9 El error o la tardanza en diagnosticar este proceso agudo puede suponer la pérdida de la glándula testicular y por ello el médico general o pediatra, que son losque suelen inicialmenteobservara estospacientes, debenconocer la existencia de esta patología, su diagnóstico y tratamiento precoz. De todas formas, aunque la situación anatómica del testículo y su contenido permiten realizar una exhaustiva exploración física, desgraciadamente todavía la remota posibilidad de una torsión del cordón espermático queda muchas veces descartada del diagnóstico diferencial al no pensar en ella.

  • Urology & Incontinence
    Urology & Incontinence - Glossary of Terms Anti-reflux Refers to a tube or collapsible material within a urine collection device to help prevent urine from reentering the tubing. Applicator collar Found on some Hollister male external catheters, a plastic guide with notches for the thumb and forefinger to assist proper placement against the tip of the penis. Aseptic intermittent catheterization The process of performing intermittent catheterization using sterile equipment and inserting the catheter in a sterile way. This would include a sterile ready-to-use product that can be inserted with gloves using a no-touch technique (e.g., the Advance Plus intermittent catheter or a VaPro hydrophilic catheter). Benzalkonium chloride (BZK) An antimicrobial solution used for cleansing the urethral opening prior to inserting an intermittent catheter. Does not stain skin or clothing. Bladder A collapsible balloon-like muscular organ that lies in the pelvis and functions to store and expel urine. Bladder catheterization A procedure in which a catheter is passed through the urethra or stoma into the bladder, usually for the purpose of draining urine. Bladder control The ability to control urination. Bladder diary A printed or electronic form to keep track of when one urinates or leaks urine. Catheter (urinary) A special type of hollow tube inserted through the urethra or a stoma to the bladder to withdraw urine or instill medication. Catheterization The process of inserting a tube into the bladder to drain urine. Clean intermittent catheterization The process of emptying the bladder using a clean intermittent catheter. It involves inserting and removing a catheter, typically several times a day.
