How babies are made: Explained in a simple way

How babies are made? Most of the parents have been asked this question by their kids? Generally, parents either feel shy or get confused on how to answer this tricky question. However, if you are going to be a parent and want to find out how babies are made, then look no further. Here we will be discussing step by step process that will help you understand how you will be able to develop a new life in your womb.

A woman conceived when her egg is fertilized by man’s sperm. It is really this simple. Nevertheless,here we will try to understand this with a clearer and detailed explanation. Firstly,we will be discussing about woman’s body, proceeding with how sperms are made and finally coming to what happens when you are having sex and how a new life is born.

How an egg is hatched inside the woman’s body:

  1. It all starts in the ovaries. Ovaries are two in number attached to either side of your uterus or womb. They are oval in shape and packed with eggs. Eggs are made in a girl’s body even before she is born. In general, a baby girl is born with around 1-2 million eggs in her ovaries. Several eggs start dying off almost instantly and later on, as they age,eggs start to decrease in number. A lady is likely to release around400 eggs during her fertile years. Fertile years are the years between a girl’s first period and the menopause.
  2. Certain numbers of eggs start to reach maturity in one of your ovaries during each menstrual cycle. During ovulation the ripest egg is released from your ovary, this process is known an ovulation. The nearest fallopian tube quickly sucks up the egg. Fallopian tubes have a tulip shaped opening and they are two in number. Length of each tube is about 10 cm and they lead from the ovaries to the uterus.
  3.  Ovulation is generally 12-14 days before your next period. You can know about signs of ovulations and menstrual cycle in our blog posts on signs of ovulation and best time to conceive.
  4. The released egg needs to be fertilized by male sperm in 24 hours after its release, because life span of an egg is up to 24 hours. If your egg meets up with a healthy sperm during its journey from ovary to uterus, the process of baby making starts. If not, egg disintegrates byending its journey in uterus.
  5. If you have not conceived, the ovary stops making hormones known as progesterone and oestrogen. These hormones assist in maintaining pregnancy. As the levels of hormones drop, the thickenedlining of womb or uterus starts shedding and you will have your periods. The remains of disintegrated eggare also shed at the same time.

How sperms are made inside the man’s body:

  1. Unlike women’s bodies, men’s bodies are almost continuously at work. They produce millions of microscopic sperm. The main goal of each sperm is to swim towards an egg and penetrate it.
  2. From start to finish,it takes 2-3 months to develop a new sperm cell. With each ejaculation,at least 40 million sperms are released. This means that man has to make sperm on a regular basis throughout their adult lives.
  3. The hormone that is responsible for producing sperms in men is testosterone. Sperm production initiates inthe testicles. Testicles are sensitive to temperature as a result hang outside the body.Generally, 34 degrees C is considered to be the suitable temperature for testicles to produce healthy sperm. Once the sperm is created, it is stored in each testicle in a 6meter long coiled tube- epididymis. The sperm is scooped up and mixed with semen just before ejaculation.
  4.  Even though millions of sperms are produced and released on ejaculation, only one sperm can fertilize each egg.
    Sperm with X chromosome will make a baby girl and sperm with Y chromosome will make a baby boy.

What happens when you are having sex:

  1.  In addition to all the pleasure, there are number of things that you experience or don’t experience. However, everything that happens in your body during sex is of utmost importance and has significance.
  2.  Having an orgasm also has a vital biological function. In men, orgasm boosts sperm-rich semen into vagina and up towards the cervix at approximately 10 miles/hour. The force of ejaculation provides the sperm a good advantage on their journey to egg. For conception to happen a woman doesn’t need to have anorgasm. Tender uterine contractions can assist the sperm in its journey.

What happens after sex:

  1. Once you are done making out, your job is done, but the sperms have to make a tough journey. The millions of sperms that made entry in your vagina,begun their journey to find your egg. During their journey, they have to come across number of hurdles, which can include your cervical mucus, (during your non-fertile days it seems like a thick net). However, when you are most fertile, it is very stretchy and slippery which assists sperm to swim easily.
  2.  Overall sperms have to travel almost 18 cm from the cervix through the uterus to the fallopian tubes. It can take from 45 minutes to 12 hours for a sperm to find the egg. Nevertheless, sperm can survive inside you for up to 7 days, so even if you will ovulate within this time frame then also there can be chances of getting pregnant.
  3. The mortality rate for sperm is very high;consequently,only a few dozen make it to the egg. The remaining get lost, trapped or die during their journey. The competition for the last few is even tougher. Each one has to work hard to penetrate the egg’s outer shell and get inside before the others. The egg needs to be fertilized in 24 hours from its release. When the toughest sperm of the lot, penetrates the egg, the egg changes right away and prevents any others to get in.

A new life is created:

  1. The penetrated sperm and egg combine to create a new cell that will quickly start dividing. A bundle of new cells is developed called blastocyst. It continues to travel down the fallopian tube towards the uterus. This journey can take few days. When blastocyst attaches itself to the wall of your uterus, you get pregnant. There it will be developed in to an embryo and placenta.
  2. Sometimes, the blastocyst implants itself, somewhere other than uterus (generally in fallopian tube). This type of pregnancy is called as ectopic pregnancy and is a medical emergency. The pregnancy can take place effectively and successfully only in uterus, as a result, this type of pregnancy has to be removed completely, or it can even damage fallopian tube.
    A visit to your doctor is highly recommended, if your periodgets delayed than usual or does not happen.
