The primary function of the male reproductive system is to produce and deliver semen, which contains male gametes (sperm), to the site of fertilization.
Ovulation is the process by which a mature egg is released from the ovary into the Fallopian tube, occurring approximately every 28 days in a typical menstrual cycle.
Menstruation is the monthly discharge of blood and tissue from the uterus that occurs if fertilization does not take place, resulting from the breakdown of the uterine lining.
Fertilization is the fusion of a sperm and an egg to form a single-celled zygote, marking the beginning of a new organism's development.
Implantation is the process by which a ball of dividing cells (the embryo) becomes embedded in the uterine wall, which is crucial for establishing a pregnancy.
Main health issues include sexually transmitted diseases (STDs) such as gonorrhea, syphilis, genital herpes, and HIV/AIDS, which can cause damage to the reproductive system and infertility.
STDs can be prevented through abstinence, the use of condoms, and regular health screenings.
During puberty, the male body experiences increased testosterone production, leading to hair growth on the face and body, deeper voice, and the development of secondary sexual characteristics.
The ovaries produce eggs and secrete female hormones such as estrogen and progesterone, which regulate the menstrual cycle and support pregnancy.
The uterus holds and supports the developing fetus during pregnancy, providing a suitable environment for growth and development.
The gestation period is the approximately 9-month duration of embryonic and fetal development in the uterus, crucial for the proper growth and maturation of the fetus before birth.
The placenta links the blood supply of the mother and fetus, transporting oxygen and nutrients to the fetus while removing carbon dioxide and waste products.
The Fallopian tubes transport the egg from the ovaries to the uterus and serve as the site for fertilization.
Foetal alcohol syndrome can cause damage to the brain and nervous system, leading to altered facial features and developmental issues in the child.
Copulation is the act of sexual intercourse, involving vaginal penetration and the ejaculation of semen.
During ejaculation, semen is discharged from the erect penis and deposited in the vagina, allowing sperm to travel towards the egg for potential fertilization.
Puberty is triggered by hormonal changes, primarily the increase in sex hormones such as testosterone in males and estrogen in females, leading to sexual maturation.
Secondary sexual characteristics are physical traits that develop during puberty, distinguishing males from females and playing a role in sexual attraction and reproduction.
Each month, the female body prepares for potential pregnancy through the menstrual cycle, which includes ovulation, thickening of the uterine lining, and eventual menstruation if fertilization does not occur.
The cervix is the lower part of the uterus that connects with the vagina, playing a crucial role in allowing sperm to enter the uterus and serving as a barrier during pregnancy.
