Organ where sperm are manufactured

Watch this video to learn about a vasectomy. Because the ductus deferens is physically accessible within the scrotum, surgical sterilization to interrupt ejaculation of sperm can be performed by cutting and sealing a small section of the ductus vas deferens. The parasympathetic division of the autonomic nervous system regulates erection, whereas ejaculation is triggered by sympathetic impulses. Inside the seminiferous tubules are six different cell types. At birth, a female's ovaries contain hundreds of thousands of undeveloped eggs, each surrounded by a group of cells to form a follicle sac. In the female, the ovaries produce estrogen, progesterone and other hormones affecting the sex drive and fertility. Used with permission article icon.

Male Reproductive System

Sperm are produced in the testes and then are transported by a series of ducts until they exit the penis via the urethra. Ovaries on either side of the uterus pass their eggs into feathery ducts that lead to the uterus through fallopian tubes. Urine exiting the body from the urinary bladder also passes through the urethra. Preputial Glands These are small sebaceous exocrine glands glands that do not secrete directly into the blood stream. The urethra is a single tube that extends from the bladder to the tip of the penis and through which urine passes out of the body. Not all human sperm cells look the same.

Aggressive forms of prostate cancer, in contrast, involve metastasis to vulnerable organs like the lungs and brain. Breast milk is produced by the mammary glands, which are modified sweat glands. Here, the vas deferens joins with the seminal vesicle to form the ejaculatory duct, which passes through the prostate and empties into the urethra. Watch this video to explore the structures of the male reproductive system and the path of sperm that starts in the testes and ends as the sperm leave the penis through the urethra. Normally, just one follicle fully matures, rupturing and releasing an ovum through the ovary wall in a process called ovulation.
