While investigating facts about Sperm Cells and Sperm Cell Diagram, I found out little known, but curios details like:
Scientists can use a person's own stem cells to make male eggs and female sperm. They have also successfully fertilized a male mouse with an egg cell made of its own cells, producing healthy offspring only from a single mouse's genome. So far, this has not been tested with humans.
how sperm cells are produced?
Men who are receiving chemo should avoid causing pregnancy during and for some time after treatment because chemo may damage the DNA in sperm cells. This could lead to birth defects.
What kills sperm cells in a woman?
In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what happens to a spermatid to change it into a sperm cell. Here are 50 of the best facts about Sperm Cell Function and Sperm Cell Function And Structure I managed to collect.
what sperm cells do?
We were not the 'fastest sperm', but rather the lucky ones that reached the egg after many others have broken down the thick layers of cells protecting it.
Human egg and sperm cells can be created from the skin cells of any two humans, regardless of gender, allowing for reproduction
Some fruit flies have sperm cells up to 5.8 cm (2.3 inches) long
The average human sperm cell or spermocyte contains about 37.5Mb of genetic data. So when orgasm occurs, roughly 1.5Gb of data is ‘ejaculated’ in about 3 seconds, a data transfer rate 6 orders of magnitude, or a few million times, faster than an average internet connection.
Sperm cells can live for up to 30 hours after a man has died. The sperm can be gathered and used for posthumous fertilization.
The egg cell is the biggest cell in the human body and the sperm cell is the smallest
Scientists have found what appears to be a fossilized sperm cell from an ancient marine species. This is the oldest and biggest fossil of a sperm ever found, at least of its kind.
Scientists are going to try and bring back the northern white rhino from extinction by combining the eggs from the southern white rhino with the cryopreserved sperm of a northern white rhino to create viable embryos and embryonic stem cells!
Spawning takes place during the night. Females can produce 10.000 to 130.000 eggs per season. They (females) release eggs while they swim vertically to the surface of the water together with one or two males who release sperm cells at the same time.
Female mates with more than one male and collects sperm cells inside her body. She lays up to 100 eggs each day. Female can lay up to 2000 eggs in a lifetime.

You can easily fact check why are egg cells large and sperm cells small by examining the linked well-known sources.
If you line up all the sperm cells from one ejaculation head to tail, they would strech six miles.
Vampire squids have internal fertilization. Male ejects sperm cells into the female's sac. Female releases eggs and takes care of them until they hatch. Incubation period lasts 13 months.
When two tripod fish meet, one fish donates eggs, while other donates sperm cells. Both types of cells are released into the water, where fertilization takes place.
Just like many other sea creatures, sea urchins reproduce by releasing eggs and sperm cells in the water. This type of reproduction is called external fertilization.
Belt-like swollen area on the earthworm’s body is called clitelum. It secretes slimy substance that forms capsule which protects eggs (sperm cells and eggs merge inside the capsule and form embryos). Encapsulated, lemon-shaped structure with eggs is called cocoon.
When sperm cell and egg cell unite?
The penis head is shaped like that so it can scoop out the previous mate's semen to make sure YOUR sperm cells get to the womb
How sperm cells are formed?
Mating season of silver arowanas takes place at the beginning of the flooding season. Fertilization takes place in the water (males and females release sperm cells and eggs directly into the water). Female produces 50 to 250 eggs per season.
Males and females swim above gravelly bottom and release eggs and sperm cells. Females can produce up to 600.000 eggs per year
Females release from 20 000 to 40 000 eggs into the water. They will be fertilized with sperm cells released by males. This type of fertilization is called external.
Fertilization of eggs takes place in the open sea (males and females release sperm cells and eggs directly into the water). Female is able to produce 2 to 3 million eggs per season which are usually released in two separate sets (second set is released two days after the first set).
Each sperm cell has 37.5MB of data and each 'load' contains around 15.8 TB of data
When sperm cell enters an egg?
Humsters", a hybrid cell line made from hamster eggs fertilized with human sperm. Humsters are routinely created for mainly two reasons: To avoid legal issues with working with pure human embryonic stem cell lines and to assess the viability of human sperm for in vitro fertilization.
Male grasps female from behind during the copulation and releases sperm cell on the hundreds of eggs that female expels from the body. Fertilized eggs are arranged in the form of gelatinous strings.
Atlantic halibut has external fertilization (males and female release sperm and egg cells directly into the water). Older females produce around two million eggs per season. Fertilized eggs float freely in the water until they hatch, 16 days later.
Life cycle of Christmas fern consists of two morphologically different generations: sporophyte and gametophyte. Sporophyte generation produces spores, miniature reproductive units. They give rise to development of gametophyte generation. Gametophyte produces male and female reproductive cells: sperms and ova. Fusion of these two types of cells gives rise to next sporophyte generation.
The first person to see live sperm cells under a microscope collected them from his wife after sex, to avoid sin. He wrote: "What I investigate is only what, without sinfully defiling myself, remains as a residue of conjugal coitus."
How sperm cells are adapted to their function?
Sperm cells holds 13,500 TB of genetic information overall that is released upon ejaculation.
Males and females release millions of eggs and sperm cells into the water, where fertilization takes place (external fertilization). Despite huge number of eggs, only few eggs manage to survive and hatch due to huge number of predators in the sea.
Female releases up to 100.000 eggs in the water at the same time when male releases sperm cells. Larvae (fry) hatch from the fertilized eggs couple of weeks later.
Fertilization (fusion of reproductive cells) occurs in the water after release of huge amount of eggs and sperm cells.
Sporophyte generation produces spores (miniature cells), basic units of asexual reproduction. When exposed to moisture, spores germinate and develop prothallus - green, heart-shaped structure which represents gametophyte generation. Prothallus produces male and female reproductive structures filled with sperm cells and eggs. Old World climbing fern is monoecious species (it produces both types of reproductive structures on the same prothallus). Like other species of fern, Old World climbing fern requires water for the successful fertilization of eggs (fusion of eggs and sperm cells takes place in the water). Fertilized eggs develop into sporophyte generation and cycle starts all over again.
You are more likely to win the powerball jackpot than be one of the 500 million sperm cells released during a single ejaculation. Congrats to all the lucky lottery winners of life reading this post.
Mating season of barracudas takes place in the spring. Males and females release eggs and sperm cells in the water where they will combine to form fertilized eggs. Females produce and release more than 1000 eggs but only few eggs will manage to survive until the adulthood.
Giant tube worms have external fertilization. Males and females release eggs and sperm cells directly into the water (by retracting their plumes). Larvae are mobile and equipped with mouth and gut, because they need to collect bacteria that are essential for the second part (sedentary) of their life.
A male sperm is the smallest cell in the human body, and the female ovum (or egg) is the largest.
Reproduction of ferns takes place in two morphologically different phases known as sporophyte and gametophyte. Sporophyte generation can be easily recognized because it looks like typical fern. Sporophyte produces spores that grow into heart-shaped structure called gametophyte. Gametophyte produces male and female reproductive organs. Ferns live in the moist habitats because they require water for successful fertilization. After merging of the sperm and egg cells, new fern develops and cycle starts all over again.
It takes about 72 days for a sperm cell to be created, mature, and get ejaculated.
Females can produce from 850.000 to 3 million eggs per season (older females produce more eggs). Fertilization of eggs takes place in the water, where they merge with sperm cells released by males.
Fifth pair of legs is small and specialized for transfer of sperm cells during the mating and for cleaning of fertilized eggs.
The Drosophila bifurca, a fruit fly, produces a single sperm cell 6 centimeters long - 20 times the length of the fly itself.
