Enseñar a los adolescentes sobre los órganos reproductivos puede ser una tarea incómoda. Tomar este tema con un enfoque científico aliviará gran parte de ese estrés. Los órganos reproductivos se aplican a todos. Esta es la anatomía de nuestros cuerpos y, desde un punto de vista científico, no es diferente a hablar sobre el corazón, el cerebro, etc.

PATH OF REPRODUCTIVE CELLS
Reproduction
Reproduction can be a complicated process. Let's break it down and find out how it works!
Reproduction can be made simple by following the development and path of reproductive cells.

REPRODUCTIVE CELLS
Sperm cells are the male reproductive cells formed in the testes. An egg is the female reproductive cell formed in the ovaries.
Deslizar: 3
TESTIS
Testes are egg-shaped organs where the sperm is produced. Testes are made up tightly coiled tubes called seminiferous tubules.
Deslizar: 4
EPIDIDYMIS
After being produced in the seminiferous tubules, sperm travel to the epididymis, where they mature.
Deslizar: 5
VAS DEFERENS
The vas deferens is a long tube that connects the epididymis to the urethra. This is the path for sperm cells.
Deslizar: 6
PROSTATE
The prostate secretes an alkaline (basic) fluid that neutralizes the acids in the female reproductive system.
Deslizar: 7
SEMINAL VESICLES
Seminal vesicles produce a fluid rich in sugars that sperm use for energy. This fluid, added with the fluid from the prostate gland, will be combined with sperm cells to make semen.
Deslizar: 8
URETHRA AND PENIS
Sperm leave the body by passing through the urethra. The penis deposits sperm in the female reproductive system during sexual activity.
Deslizar: 9
OVARIES
Each month, the female reproductive system prepares for a possible pregnancy by releasing a mature egg cell from the ovaries.
Deslizar: 10
VAGINA
The vagina is a muscular canal that leads from the outside of the body to the uterus. Sperm cells enter through the vagina during intercourse.
Deslizar: 11
CERVIX
The cervix is a narrow portion at the bottom of uterus that provides an opening to the uterus from the vagina. The cervix will need to dilate during labor.
Deslizar: 12
UTERUS
The uterus is a hollow, muscular organ which expands during pregnancy. The uterine walls build up and break down during the ovulation cycle, causing menstruation.
Deslizar: 13
FERTILIZATION
When a sperm cell and egg unite, cell division begins. If fertilization takes place, it will happen in the fallopian tubes.
Deslizar: 14
FALLOPIAN TUBES
The fallopian tubes serve as a passageway for the ovum from the ovary to the uterus. Smooth muscle contractions and cilia move ovum towards the uterus.
Deslizar: 15
UTERUS
If an ovum is fertilized, it will implant in the wall of the uterus, starting the first stages of pregnancy.

PATH OF REPRODUCTIVE CELLS
Reproduction
The first signs of pregnancy usually show up after about two weeks. About half the time, a fertilized egg does not implant and pregnancy will not begin.
