The male reproductive system includes internal structures like the testes, epididymis, ductus deferens, seminal vesicles, prostate, and penis. The testes are held in the scrotum and produce sperm. Sperm travel through the epididymis, ductus deferens, and ejaculatory duct before mixing with fluids from the seminal vesicles and prostate to form semen, which is ejaculated through the urethra in the penis during orgasm. Blood flows into the structures through arteries and drains out through veins, while nerves provide sensation and control erectile function and ejaculation.

Francesca Gottschalk - How can education support child empowerment.pptxEduSkills OECD
Francesca Gottschalk from the OECD’s Centre for Educational Research and Innovation presents at the Ask an Expert Webinar: How can education support child empowerment?
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

2. Male Reproductive System The reproductive system in men has components in the abdomen, pelvis, and perineum.
3. Male Reproductive System The major components are a testis, epididymis, ductus deferens, and ejaculatory duct on each side, and the urethra and penis in the midline. Three types of accessory glands are associated with the system: A single prostate; A pair of seminal vesicles; A pair of bulbourethral glands.
5. The scrotum The scrotum is an outpouching of the lower part of the anterior abdominal wall. It contains the testes, the epididymides, and the lower ends of the spermatic cords.
6. The scrotum It is divided on its surface into two compartments by a raphé, which is continued forward to the under surface of the penis, and backward, along the middle line of the perineum to the anus. Each compartment contains one of the two testes, and one of the epididymides.
7. The scrotum The wall of the scrotum has the following layers: Skin Superficial fascia Spermatic fasciae Tunica vaginalis
8. The scrotum Skin The skin of the scrotum is thin, wrinkled, and pigmented and forms a single pouch. A slightly raised ridge in the midline indicates the line of fusion of the two lateral labioscrotal swellings. Superficial fascia This is continuous with the fatty and membranous layers of the anterior abdominal wall. The fat is replaced by smooth muscle called the dartos muscle. This is innervated by sympathetic nerve fibers and is responsible for the wrinkling of the overlying skin.
9. The scrotum Spermatic fasciae It has three layers which lie beneath the superficial fascia and are derived from the three layers of the anterior abdominal wall on each side. The external spermatic fascia is derived from the aponeurosis of the external oblique muscle; the cremasteric fascia is derived from the internal oblique muscle; and, finally, the internal spermatic fascia is derived from the fascia transversalis. Tunica vaginalis This lies within the spermatic fasciae and covers the anterior, medial, and lateral surfaces of each testis.
10.
11. Lymph Drainage of the Scrotum Lymph from the skin and fascia, including the tunica vaginalis, drains into the superficial inguinal lymph nodes .
12. Testes Testis has ellipsoid-shaped. Testes develop in the abdomen and move before birth into the scrotum. The left testis usually lies at a lower level than the right.
13. Testes The testis are covered by: A closed sac of peritoneum (the tunica vaginalis), which originally connected to the abdominal cavity. Normally after testicular descent, the connection closes, leaving a fibrous remnant. It is covered by a fibrous capsule called the tunica albuginea.
15. Testes In the inner surface of the capsule is a series of fibrous septa that divide the interior of the organ into lobules. Lying within each lobule are 1 to 3 coiled seminiferous tubules. The tubules open into a network of channels called the rete testis. Small efferent ductules connect the rete testis to the upper end of the epididymis.
17. Epididymis The epididymis is a single, long coiled duct that courses along the posterolateral side of the testis. The tunica vaginalis covers the epididymis with the exception of the posterior border.
19. Epididymis It has two distinct components: The efferent ductules, which form an enlarged coiled mass that sits on the posterior superior pole of the testis and forms the head of the epididymis; The true epididymis, which is a single, long coiled duct into which the efferent ductules all drain, and which continues inferiorly along the posterolateral margin of the testis as the body of epididymis and enlarges to form the tail of epididymis at the inferior pole of the testis.
20. Arterial Blood Supply of the Testis and Epididymis The testicular artery is a branch of the abdominal aorta.
21. Venous drainage of the Testis and Epididymis The testicular veins emerge from the testis and the epididymis as a venous network, the pampiniform plexus. This becomes reduced to a single vein as it ascends through the inguinal canal. The right testicular vein drains into the inferior vena cava, and the left vein joins the left renal vein.
22. Lymphatic Drainage of The Testes Lymphatic drainage of the testes is to the para-aortic lymph nodes.
23. Ductus deferens (Latin: "carrying-away vessel"), also called vas deferens. The ductus deferens is a long muscular duct that transports spermatozoa from the tail of the epididymis to the ejaculatory duct.
24. Ductusdeferens course The vas arises from the tail of the epididymis and traverses the inguinal canal to the deep ring, passes downwards on the lateral wall of the pelvis almost to the ischialtuberosityand turns medially to cross the ureter posterior to the bladder. It continues inferomedially along the base of the bladder, anterior to the rectum, almost to the midline, where it is joined by the duct of the seminal vesicle to form the ejaculatory duct.
25. Ductusdeferens course The terminal part of the vas deferens is dilated to form the ampulla of the vas deferens. The ejaculatory duct penetrates through the prostate gland to connect with the prostatic urethra.
26. Seminal vesicle The seminal vesicles are an accessory gland of the male reproductive system . The seminal vesicles are two lobulated organs about 2 in. (5 cm) long lying on the posterior surface of the bladder .
27. Seminal vesicle On the medial side of each vesicle lies the terminal part of the vas deferens. Posteriorly, the seminal vesicles are related to the rectum. Inferiorly, each seminal vesicle narrows and joins the vas deferens of the same side to form the ejaculatory duct.
28. Blood Supply of Seminal vesicle Arteries The arterial blood supply from, the inferior vesicle and middle rectal arteries. Veins The veins drain into the internal iliac veins.
29. Ejaculatory Ducts The two ejaculatory ducts are each less than 1 in. (2.5 cm) long and are formed by the union of the vas deferens and the duct of the seminal vesicle. The ejaculatory ducts pierce the posterior surface of the prostate and open into the prostatic part of the urethra, close to the margins of the prostatic utricle; their function is to drain the seminal fluid into the prostatic urethra.
30.
31. Prostate The prostate is an unpaired accessory structure of the male reproductive system that surrounds the urethra in the pelvic cavity . It lies immediately inferior to the bladder, above the theurogenitaldiaphragm, posterior to the pubic symphysis, and anterior to the rectum.
32. Prostate The prostate is shaped like an inverted rounded cone with a larger base, which is continuous above with the neck of the bladder, and a narrower apex, which rests below on the pelvic floor. The inferolateral surfaces of the prostate are in contact with the levatorani muscles that together cradle the prostate between them.
34. Prostate The two ejaculatory ducts pierce the upper part of the posterior surface of the prostate to open into the prostatic urethra at the lateral margins of the prostatic utricle.
35. Relations of Prostate Superiorly The base of the prostate is continuous with the neck of the bladder. The urethra enters the center of the base of the prostate. Inferiorly The apex of the prostate lies on the upper surface of the urogenital diaphragm. The urethra leaves the prostate just above the apex on the anterior surface
36. Relations of Prostate Anteriorly The prostate is related to the symphysispubis. The prostate is connected to the posterior aspect of the pubic bones by the puboprostatic ligaments. Laterally The prostate is embraced by the anterior fibers of the levatorani. Posteriorly The prostate is closely related to the anterior surface of the rectal ampulla and is separated from it by the rectovesical septum (fascia of Denonvilliers).
37. Structure of the Prostate Enclosed within thin dense fibrous capsule Inner loose sheath derived from pelvic fascia – “prostatic sheath” Continuous inferiorly with superior fascia of urogenital diaphragm Posteriorly it is part of rectovesical septum Separates bladder, seminal vesicles and prostate from rectum Prostatic venous plexus lies between fibrous capsule and prostatic sheath.
38. Structure of the Prostate Prostatedivided into: Two lateral lobes One median lobe Anterior and posterior lobes
39. Structure of the Prostate Anterior Tissue lying anterior to urethra No glands; fibromuscular tissue only Median Cone-shaped region between ejaculatory ducts and urethra Lateral (left & right) Main mass of gland, continuous posteriorly Separated by prostatic urethra Posterior Describes postero-medial part of lateral lobes palpable through rectum on DRE.
41. Blood Supply of The Prostate Arterial supply Arteries derived from internal pudenal, inferior vesical and middle rectal arteries (branches of internal iliac) Venous drainage Veins form prostatic venous plexus around sides and base of prostate – located between capsule and sheath Drains into internal iliac veins Also communicates with vesical venous plexus and vertebral venous plexuses.
42. Lymphatics and innervation of The Prostate Lymphatic drainage Lymph vessels terminate in internal iliac and sacral lymph nodes Some vessels from posterior surface pass with lymph vessels from bladder to external iliac LN’s Innervation Parasympathetic fibres arise from pelvic splanchnic nerves Sympathetic fibres from inferior hypogastric plexuses
43.
44. Penis The penis is a pendulous organ suspended from the front and sides of the pubic arch and containing the greater part of the urethra.
45. Penis It consists of internal root, external shaft, & glans. Root: the portion of the penis that extends internally into the pelvic cavity. Shaft: the length of the penis between the glans and the body. Glans: the head of the penis; has many nerve endings. Foreskin: a covering of skin over the penile glans.
47. Penis The root of penis consists of the two crura, which are proximal parts of the corpora cavernosaattached to the pubic arch, and the bulb of penis, which is the proximal part of the corpus spongiosumanchored to the perineal membrane.
48. Penis The body of the penis is essentially composed of three cylinders of erectile tissue enclosed in a tubular sheath of fascia (Buck's fascia). The erectile tissue is made up of two dorsally placed corpora cavernosa and a single corpus spongiosum applied to their ventral surface . At its distal extremity, the corpus spongiosum expands to form the glans penis, which covers the distal ends of the corpora cavernosa. On the tip of the glans penis is the slitlike orifice of the urethra, called the external urethral meatus.
50. External penile structures Corona: the rim of the penile glans. Frenulum: thin strip of skin connecting the glans to the shaft on the underside of the penis. Both are highly sensitive areas to the touch
51. Blood Supply of The Penis Arteries The corpora cavernosa are supplied by the deep arteries of the penis ; the corpus spongiosum is supplied by the artery of the bulb. In addition, there is the dorsal artery of the penis. All the above arteries are branches of the internal pudendal artery. Veins The veins drain into the internal pudendal veins.
52. Lymphatics and innervation of The Penis Lymph Drainage The skin of the penis is drained into the medial group of superficial inguinal nodes. The deep structures of the penis are drained into the internal iliac nodes. Nerve Supply Sensation The nerve supply is from the pudendal nerve and the pelvic plexuses. Erectile function Parasympathetic(excitatory) Sympathetic (inhibitory)
53. Analagous structures in male and female sexual anatomy Male Glans Foreskin Shaft Scrotal sac Testes Female Clitoris Clitoral hood Labia minora Labia majora Ovaries
