Difference between “boy sperm” and “girl sperm”

Y Sperm Make Boys



There are two types of sex chromosomes: X and Y. One of each is contributed by each parent.

Males have two distinct sex chromosomes: XY. Females have two of the same kind of sex chromosome: XX.

Mother supplies only an X chromosome, while father can supply both types. If the father’s sperm is carrying a Y chromosome, the baby will be a boy. If it is carrying an X chromosome, the baby will be a girl.
Semen contains equal numbers of Y and X sperms.

Difference between “boy sperm” and “girl sperm” in a nutshell:

BOY SPERM (Y):
- smaller
- faster
- more sensitive

GIRL SPERM (X):
- bigger
- slower
- tougher


Not all sex determination systems are genetic in nature. And, some species don’t even have a sex determination system!

Did you know that there are some really interesting sex determination systems in animal kingdom?

For instance, baby alligators’ sex is determined by the temperature at which the egg was incubated. Some snails practice sex change: adults start out male, and then become female. In tropical clown fish, the dominant individual in a group becomes female - while the other ones are male!
On the other hand, earthworms and some snails are hermaphrodites.
A few species of lizard, fish, and insect are all female and reproduce by parthenogenesis.
In some bacteria, sex is determined by infection. Ok, I won’t pretend I understand all this, but it's interesting!:)

When a woman has her period, she is menstruating. The menstrual blood is partly blood and partly tissue from the inside of the uterus (womb). It flows from the uterus through the small opening in the cervix, and passes out of the body through the vagina. Menstruation is part of the menstrual cycle, which helps a woman's body prepare for the possibility of pregnancy each month. A cycle begins on the first day of bleeding and continues up to, but not including, the first day of the next period. The average menstrual cycle is around 28 days long. However, a cycle can range anywhere from 21 days to 35 days or more. The length of a woman's cycle may change a little from month to month. Most menstrual periods can last from 1 to 8 days, with the average being 4 to 5 days. Periods are a normal part of a w

A professor at CCNY for a physiological psych class told his class about bananas. He said the expression 'going bananas' is from the effects of bananas on the brain. Never put your banana in the refrigerator! !! This is interesting.After reading this, you'll never look at a banana in the same way again. Bananas contain three natural sugars - sucrose, fructose and glucose combined with fiber. A banana gives an instant, sustained and substantial boost of energy. Research has proven that just two bananas provide enough energy for a strenuous 90-minute workout. No wonder the banana is the number one fruit with the world's leading athletes. But energy isn't the only way a banana can help us keep fit. It can also help overcome or prevent a substantial number of illnesses and conditions, making it a must to add to our daily diet.
