Human reproductive system
The human reproductive system usually involves internal fertilization by sexual intercourse. During this process, the male inserts his penis into the female's vagina andejaculates semen, which contains sperm. A small portion of the sperm pass through the cervix into the uterus, and then into thefallopian tubes for fertilization of the ovum. Only one sperm is required to fertilize the ovum. Upon successful fertilization, the fertilized ovum, or zygote, travels out of the fallopian tube and into the uterus, where it implants in the uterine wall. This marks the beginning of gestation, better known aspregnancy, which continues for nine months as the foetus develops. When the foetus has developed to a certain point, pregnancy is concluded with childbirth or labor. During labor, the muscles of the uterus contract and the cervix dilates over the course of hours, and the baby passes out of the vagina. Human infants are nearly helpless and require high levels of parental care. Infants rely on their caregivers for comfort, cleanliness, and food. Food may be provided by breastfeedingor formula feeding.[1]
The female reproductive system has two functions: The first is to produce egg cells, and the second is to protect and nourish thefetus until birth. The male reproductive system has one function, and it is to produce and deposit sperm. Humans have a high level of sexual differentiation. In addition to differences in nearly every reproductive organ, numerous differences typically occur insecondary sex characteristic

Male reproductive system consist of a pair of testes , two sperm duct , urethra and a penis.
☆ Testes ( singular : testis ) :
A Male has two testes . testes are oval in shape , they lie in a small muscular pouch called scrotum which is outside the abdominal cavity.
Function of testes is to produce Male gametes called sperms and also produce the Male sex hormone called testosterone.
☆ Sperm Duct ( Vas deferens ) :
The sperm duct starts from the testis and joins the urethra. it carries sperm to the urethra by the muscular action of its walls. here the fluid produced by the seminal vesicles mixes with the sperms to produce semen , it provide nourishment to the sperms.
☆ Urethra :
It's a long tube which starts from the urinary bladder to carry urine . the semem from sperm duct also joins the urethra.
☆ penis :
It is a long and thick muscular organ that injects the sperm into the female's body.
