tract for about 24 to 72 hours.

of 400 million/ ejaculation 90 seconds-
cervix 5 minutes.- end of fallopian tube
SEMEN
16
COMPONENTS OF ACCESSORY GLANDS
➢ Liquid portion acts as a transport medium to
dilute sperm
➢ Sperm are streamlined cellular ―tadpoles

➢ the acidic environment of vagina
➢ Semen inhibits bacteria
FRUCTOSE
17
EXTERNAL GENITALIA
➢ Divided sac of skin outside the abdomen that houses the testes
➢ Viable sperm cannot be produced at normal body temperature
➢ Maintains testes at 3°C lower than normal body temperature
SCROTUM
18
➢ Male organ of copulation that delivers sperm into the female reproductive tract
➢ Internally there are three areas of spongy erectile tissue around the urethra
➢ ERECTIONS occur when this erectile tissue fills with blood during sexual excitement
PENIS
19
PENIS
- Folded cuff of skin around proximal end
- Often removed by circumcision
PREPUCE
20
Male Reproductive Functions
➢ Chief roles of the male in the
reproductive process
➢ Produce sperm
➢ Produce a _______, _______
HORMONE, TESTOSTERONE
21
—————
• Begins at puberty and continues throughout
life
• Millions of sperm are made every day
SPERM PRODUCTION
22
SPERMATOGENESIS
➢ Sperm are formed in the ___________ of the testis
• Spermatogonia (primitive stem cells) begin the process by dividing rapidly
• During puberty, follicle-stimulating hormone (FSH) is secreted in increasing amounts
SEMINIFEROUS TUBULES
23
SPERMATOGENESIS
• Gametes are spermatids with — chromosomes
• ______ chromosomes are half the usual __ found in other body cells
• — is known as the ______ number (n)—half the genetic material as other body cells
IT CREATES A _______
23, 46, HAPLOID, ZYGOTE
24
➢ Final stage in ________ wherein the spermatids differentiate into mature spermatozoa
➢ Spermatids are nonmotile and not functional as sperm
➢ A streamlining process is needed to strip excess cytoplasm from a spermatid and modify it into a sperm
➢ A sperm has three regions: head, midpiece, tail
➢ Acrosome sits anterior to the sperm head (nucleus)
➢ The entire process of spermatogenesis, including spermiogenesis, takes 64 to 72 days
