the egg. Inside the fallopian tube, a mature human egg waits in a state of arrested development. Just released from the ovary, it is the largest cell in the human body. The egg is packed with nutrients, growth factors, enzymes and proteins — nearly everything it needs to jump start the development of a human embryo. Except for one little thing — it needs a sperm. If a sperm doesn’t penetrate the egg’s tough outer membrane to activate it within the next 24 hours, the egg will die.¬¬ The sperm cells

➢ It is not necessary for every human being to produce children, but in order to continue our human species, at least some people have to have children. ➢ The four main functions of the human reproductive system are: • To produce egg and sperm cells, • To transport and sustain these cells, • To nurture the developing offspring, and • To produce hormones. MAJOR ORGANS ➢ In the human reproductive system, the major organs include the external genitalia and

muscular, ridged sheath connecting the external genitals to the uterus, where the embryo grows into a fetus during pregnancy (Reproductive System, 2009.) In the reproductive process, the vagina functions as a two-way street, accepting the penis and sperm during intercourse, and roughly nine months later, and

experience being infertile can be caused by many things. Age, weight, lifestyle, occupation. A woman is considered to be infertile if she experiences any of these things. If their ovaries do not make mature eggs, if damage to the reproductive system keeps their eggs from being fertilized, or if a fertilized egg cannot implant and grow inside the uterus. A woman’s fertility is evaluated

sterilization. Depending on a person’s sex life and personal preference there are contraceptive options for everyone. The IUD, Intrauterine Device, is inserted into the uterus of a female by her clinician. The IUD contains copper that keep sperm from joining the egg. However, not affective against sexually transmitted infection, it is considered 99.2-99.8% effective against pregnancy. There are currently two different IUD’s available at Planned Parenthood, one is ParaGard (copper IUD) that can be left

most likely to conceive when her egg is released which normally occurs 12-14 days before her period begins. When ovulation occurs in the woman, an egg is released from her ovaries and passes through the fallopian tubes. If the egg finds a sperm in the fallopian tubes, the egg is fertilized. After fertilization occurs, this marks the beginning of a new stage, the Germinal Stage. During this stage, the zygote divides and begins to grow more complex. The fertilized egg then travels towards the uterus

for at least one year without success” (American Pregnancy Association). Conception and pregnancy are complicated processes that depend on a number of factors, including, but not limited to: healthy sperm production, healthy egg production, unblocked fallopian tubes that allow the sperm to reach the egg, and/or sufficient embryo quality. In order for the pregnancy to progress to full term, the embryo must be healthy and the woman’s hormonal environment must be adequate for the development

spores. The spores undergo mitosis to produce gametophytes, of which there are two separate genders. One gender is the hermaphrodite, which is rather large and heart-shaped, and produces both eggs and a small amount of sperm. The other gametophyte gender is a very small, club-shaped male, which produces sperm only. There are no female-only gametophytes (Hickok and Warne 1998). Germination occurs three to four days and full sexual maturity is attained within six days after germination. At maturity

child rearing can be seen in everyday interactions because of the standards it sets for personal behavior and group interactions. Language in early biology starts the rhetoric of the male aggressor by assuming the sperm had a dominate and aggressive role in fertilization while the egg was passive during the interaction. When research later showed

and female reproductive systems have to be different. Each system has different parts, problems and care. Each system have different purposes, the male reproductive system’s function is to produce sperm, while the female reproductive system’s function is to produce ova, store ova and house a fertilized egg. The male reproductive system is divided into two categories: internal and external reproductive organs. External organs are outside the body and internal organs are inside the body. The external
