Euglenoids are single celled organisms that use a flagellum to move their bodies. Not all euglenophytes have a flagellum. The differentiating factor is the fact that the euglenoid or euglenophyte has a single flagellum.
The flagellum (plural: flagella)
As of now, a transgender male (assigned female at birth) and a genetic female cannot conceive a child naturally. Options could include the use of a sperm donor or adoption. Consulting with a fertility specialist can provide more tailored advice and options.
The testes are responsible for producing sperm and the male sex hormone, testosterone. Sperm production occurs in the seminiferous tubules within the testes. Testosterone is important for the development of male reproductive tissues, as well as secondary sexual characteristics like muscle mass and voice deepening.
Humans need sperm cells for sexual reproduction. Sperm cells contain genetic information from the male parent, which combines with the genetic material from the female egg to create a unique offspring. This process ensures genetic diversity and the continuation of the species.

Frogs use external fertilisation, this means that the female frog lays thousands of eggs, but then the male sprays sperm on the offspring to fertilise it. So basically the sperm cell and egg cell meet when the male sprays his sperm cells over the eggs.
Its head can use to penetrate to egg cell and tail can use to move.
The flagellum (plural: flagella)
The flagella are on bacteria but are also on a man's sperm. Not only does it help the bacteria move but it also helps the sperm move. Inorder to have a baby you first need to have a egg fertilized in a woman. The sperm from a man cannot get to fertilize the egg without the flagella helping them to move. Without the flagella we will not be able to repopulate.
Earthworms use internal fertilization. During copulation, sperm is transferred from male to female through the male's specialized structures called seminal vesicles. The female then stores the sperm in her spermatheca until she is ready to fertilize her eggs.

Habitual use lowers sperm count and causes a decrease in sexdrive for men.
Internal fertilization of the females eggs through contact with male sperm during mating.
Sperm fully mature in the epididymis, a coiled tube located on the back of each testicle. The fructose that provides energy for sperm to move their tails is produced by the seminal vesicles and released into the semen, which nourishes and supports sperm during ejaculation.
