Interesting Facts About Reproductive System: Who’ve More Gametes, Men Or Women?

The reproductive system refers to a collection of genitalia and organs whose primary role is to develop a new life. Usually, the human reproductive system involves internal fertilization through sexual intercourse.
The female reproductive system is much more complex than the male’s, and mainly includes the ovaries, the vagina, and the uterus. Male reproductive system includes the prostate gland that assists to produce the seminal fluid, and the testicles, penis, and the scrotum.
The female reproductive system has two major functions: To produce egg cells, and also to nourish and protect the fetus until birth. Male reproductive system has one major function: to produce and deposit sperm.
Human beings have a high sexual differentiation level. On top of the differences in almost each reproductive organ, several differences usually occur in secondary sexual characteristics.
The human reproductive system has several amazing and mysterious facts associated with it despite being very advanced as compared to that of other higher vertebrates. Here are some of the most interesting and surprising facts about the reproductive system:
1. The Largest And The Smallest Cell Of The Human Body
The human reproductive system produces the largest and the smallest cell of the human body. The ovum released by female ovaries being the largest human cell with a diameter of approximately 120 micrometers, and the sperm being the smallest cell in the body, 3 by 5 micrometers in size.
2. Higher Pitched Voices, More Sperm
Recent studies reveal that men with higher-pitched voices have a greater sperm count. Although women usually find a deeper voice more appealing, there’s a high possibility his sperm count will be lower than that of a higher pitched guy.
3. The Average Size Of A Male Penis Is Less Than Six Inches
Although a man’s penis size varies significantly, the average size of the penis measures about 5.6 inches, in its erect state. On the other hand, the longest measured in at 10.2 inches and the smallest penis was 1.6 inches.
4. Some Mammals Don’t Have Reproductive Systems Like Ours
It’s true that some animals have similar reproductive systems, this isn’t always the case. The Kangaroos have three vaginas. One acts as a birth canal and the other two for the two penises of male kangaroos. Birds don’t have a vagina or a penis. Instead, both female and male have a cloaca.
5. The Tomatoes and Vagina are Both Acidic
Perhaps, many women don’t want their vaginas compared to a tomato. However, their acidic levels are very similar at 4.5. The reason behind the high level of acidity in the vagina of a woman is simple; it’s the only environment specific beneficial bacteria can thrive in. In fact, this bacteria is what maintain the vaginal PH level of a woman and keep it healthy.
6. Some Women Have Two Uteruses
This is unusual, but it isn’t incredibly rare either. Scientists believe this double uterus condition can affect up to one in every 2000 women. It usually occurs during development when uterus starts as two tiny tubes. Two uteruses can develop when these tubes don’t connect all of the ways.
7. The Ancient Egyptians were Using Contraceptives
Contraceptives aren’t new, in fact, they’ve been assisting to prevent unwanted pregnancies for over 4000 years. In a papyrus that was discovered recently, scientists have learned that the ancient Egyptians were very aware of how babies are made and had their own techniques for preventing it. Crocodile dung and honey were the two of the favorite techniques.

During the 17th and 18th centuries, parents and guardians of young boys in Italy were having the testicles of their sons removed. In men, the testes are responsible for the production of hormones including testosterone. When the testosterone isn’t product, boys won’t go through puberty that usually includes the deepening of the voice.
9. Males Have More Gametes Than Females
During the lifetime of a woman, she’ll only ovulate 300-400 of the one to two million eggs she was born with. On the other hand, men will produce more than 500 billion sperms in their lifetimes. Much more gametes than any woman is ever born with.
