Kissing, hugging, and rubbing clothed bodies don’t cause pregnancy. The only time pregnancy can happen is when sperm can get to an egg.

A sperm has three main parts:

• The head of the sperm contains the nucleus. The nucleus holds the DNA of the cell.
• The midpiece of the sperm is packed with mitochondria. Mitochondria are organelles in cells that produce energy.
• The tail of the sperm moves like a propeller, around and around.

A sperm cell consists of two parts, the head and the tail. The overall structure of the sperm makes it perfectly designed to carry out its function. The primary function of the sperm is to pass on the necessary biological information required to produce a new organism.

In Eutherian mammals the acrosome contains degradative enzymes (including hyaluronidase and acrosin). These enzymes break down the outer membrane of the ovum, called the zona pellucida, allowing the haploid nucleus in the sperm cell to join with the haploid nucleus in the ovum.

These steps will help you prepare yourself and your body for pregnancy and give you a better chance of having a healthy baby.

Clomiphene and gonadotropins are commonly used fertility drugs that can increase your chances of having twins. Clomiphene is a medication available only through prescription. In the United States, the brand names for the drug are Clomid and Serophene.

Doctors can’t guarantee twins at the onset of IVF, anyway. SART and the American Society of Reproductive Medicine (ASRM) have guidelines about how many embryos should be transferred to an IVF patient, based on their age, reproductive history, and embryo quality.

Side effects Please note that Clomid is a fertility medication. One important side effect is the possibility of multiple births. The probability of having twins while taking this medication is 7% (meaning 7 out of 100 women taking Clomid will get pregnant with twins). The chance of having more than twins is rare.

To form identical or monozygotic twins, one fertilised egg (ovum) splits and develops into two babies with exactly the same genetic information. To form fraternal or dizygotic twins, two eggs (ova) are fertilised by two sperm and produce two genetically unique children.

Ultrasound. Although the factors above may be signs of a twin pregnancy, the only sure way to know you’re pregnant with more than one baby is through an ultrasound. Some doctors schedule an early ultrasound, around 6 to 10 weeks, to confirm the pregnancy or check for issues.

On average, twins have lower IQ scores at 7 and 9 years old than singleton children in the same family.

The researchers found that twins at age 7 had I.Q.’s an average of 6.6 points lower than those of their singleton brothers and sisters, and that by age 9 their average I.Q. was 6.9 points lower.

Twins not only have a bestie from birth — they also live longer than singletons. And those two factors may be related, according to new University of Washington research. Analysis shows that twins have lower mortality rates for both sexes throughout their lifetimes.

But, like those who aren’t twins, identical twins all have unique fingerprints. Due to environmental factors that affect their development inside the womb, it’s impossible for identical twins to have the exact same fingerprints.

Business Insider found that it works as advertised and Face ID could not be fooled by identical twins. Mashable, on the other hand, found two sets of identical twins capable of thwarting Face ID. However, the rate for identical twins is only 3.5 per 1,000 births.
