Understanding your body is the first step to enjoying your body
What makes up your reproductive system?
The reproductive system: sometimes called the sexual organs, is the set of organs needed to make a baby, or reproduce. Your reproductive system is made up of a vulva, vagina, cervix, womb, fallopian tubes, ovaries and breasts. Unlike men, most of your reproductive system is located inside your body.
What is menstruation?
Every month or so, the lining of your womb gets thick with blood and tissue to prepare to receive a fertilized egg incase you become pregnant. If no egg is fertilized, then that lining is released out of your body as blood through the vagina. This monthly flow is called menstruation or a period and is a normal, healthy part of a woman’s life. It usually begins when a girl is between 9 and 16 years old and continues until she is 45 to 55.
What is your menstrual cycle?
Your menstrual cycle is the time from the first day of your period to the first day of your next period. Your menstrual flow on the other hand usually lasts 3 to 7 days, but it may be slightly shorter or longer while a normal menstrual cycle can be as short as 21 days or longer than 35 days. For the majority of women, their menstrual cycle is between 25-30 days long, but it’s not unusual for the number of days in each cycle to vary from month to month.
What is ovulation?
Ovulation is the release of an egg from the ovaries. A woman is born with all her eggs. Once you start your periods, one egg (occasionally two) develops and is released during each menstrual cycle. After ovulation, the egg lives for approximately 24 hours. A woman cannot get pregnant if ovulation does not occur.
How does pregnancy happen?
Pregnancy= Fertilization+ Implantation. If one sperm makes its way into the fallopian tube and burrows into the egg, it fertilizes the egg. The egg changes so that no other sperm can get in. This fertilized egg stays in the fallopian tube for about 3 to 4 days, but within 24 hours of being fertilized, it starts dividing fast into many cells. It keeps dividing as it moves slowly through the fallopian tube to the uterus. Its next job is to attach to the lining of uterus; this is called implantation.
Can you get pregnant at any time in your cycle?
In theory, during the average woman’s menstrual cycle there are six days when sex can result in pregnancy. This conception risk period, also called ‘fertile window’ is the five days before egg release (ovulation), plus the day of egg release.
What if you miss a period or your menstrual cycle is irregular?
When you miss your period or if your period is late, the most common concern is pregnancy. Taking a pregnancy test is the only way to know for sure if you are pregnant. Apart from pregnancy, many women have irregular periods from time to time — or throughout their lives. You might miss your period or your period may come earlier or later than usual or it may be much heavier or lighter than usual.
There are many reasons your menstrual cycle may change, including
- Non hormonal birth control — eg. IUDs can make your periods heavier
- Hormonal birth control such as the pill, injection, implants can make your periods lighter, make you miss your period or make it come later than usual.
- Various Medicines
- Over exercising
- Poor nutrition
- Sudden weight gain or weight loss
What makes up your reproductive system
The male reproductive system consists of a number of sex organs that plays roles in the process of human reproduction. These are the penis, the urethra, the scrotum, testes (testicles), vas deferens, seminal vesicles, and prostate. Unlike women, majority of these organs are located on the outside of the body. While the penis and the urethra (the tube through which urine passes) are part of both the urinary and the reproductive systems, the scrotum, testes (testicles), vas deferens, seminal vesicles, and prostate comprise the rest of the reproductive system.
What is sperm count
This is a measure of the number of spermatozoa inside each ejaculation or inside a quantity of of semen. This count is used as an indication of a man’s fertility. A normal sperm count should have 40 million to 300 million sperm per milliliter pf semen. Counts below 10 million are considered poor; while sperm count of 20 million or more may be fine if the sperm’s structure and motility are okay.
What is male erection
An erection is a hardening of the penis that occurs when tissue inside the penis fills up with blood. Usually, an erection causes the penis to enlarge and stand away from the body. When men become sexually aroused, hormones, muscles, nerves, and blood vessels all work with one another to create an erection.
How does pregnancy occur
The main male sex organs are the penis and the testicles which produce semen and sperm, which, as part of sexual intercourse, fertilize an egg in the female’s body; the fertilized egg (zygote) develops into a fetus, which is later born as an infant.
Men can get women get pregnant in a variety of ways, but the most common way is through unprotected vaginal sex. During unprotected sex, when a man ejaculates sperm into the vagina. The sperm can then travel up through the cervix, into the uterus, and, if an egg is present, the sperm may fertilize it. This fertilized egg can implant in the womb and grow into a baby.
Is it true that men determine baby’s gender?
This is true. Men determine the sex of a baby depending on whether their sperm that fertilizes the woman’s egg is carrying an X or Y chromosome (gene). Women’s eggs only have X chromosome while Men have both X and Y chromosome sperms, so If an X chromosome sperm combines with the X chromosome in the woman’s egg, then it will make a baby girl (XX) while if a Y chromosome sperm combines with the X chromosome in the woman’s egg, then you would have make a boy (XY).
