o Location Males Majority of the system are out of the pelvis Females Majority inside pelvis (eg. ovary, vagina, uterus) o Relation with peritoneal cavity Males Peritoneal cavity closed Females Peritoneal cavity open and exposed to outside via uterine tube o Ureter in males crosses vas deferens; in females, crosses uterine artery Male reproductive system o Testicles Gonads in charge of secretion and testosterone and sperm Two surfaces (medial and lateral) Two poles (superior and inferior) Two borders (anterior and posterior) Dense connective tissue surrounds testicles sends partitions inside testicle (known as septum) and divides testicles into lobules Tunica aluginea forms the hilum of testicle on posterior border Seminferous tubule o Production of sperm occurs here Sperm is taken out of testicle by rete testis (on posterior border of testicles) and delivered to head of epididymis (long tube that convolutes with itself and makes packed structure) Epididymis contains body and tail Maturation of sperm occurs in epididymis (sperm released from testicles it not matured) Sperm is delivered to ductus deferens When testicles descend into inguinal canal, they take layer from anterior abdominal wall Spermatic cord includes vas deferens, testicular arteries and veins, nerves, and lymphatic vessels o Cryptorchidism undescended testicle Testicles can remain in abdominal or inguinal canal and don’t take position in the scrotum If they remain, spermogenosis cannot occur o Ampulla of ductus deferens Joins to the seminal vesicle (coiled) tube accessory gland of male reproductive system; o Ejaculatory duct pierces prostate and opens to prostatic urethra o Prostate gland Sits on neck of urinary bladder Apex sits on external urethra sphincter Function is to make semen Seminal vesicle males 60% of semen o Bulbourethral gland External urethral sphincter is in deep perineal pouch in both genders

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
