spermatozoon /sper·ma·to·zo·on/ (-zo´on) pl. spermatozo´a sperm; a mature male germ cell, which fertilizes the oocyte in sexual reproduction and contains the genetic information for the zygote from the male. Spermatozoa, formed in the seminiferous tubules, are derived from spermatogonia, which first develop into spermatocytes; these in turn produce spermatids by meiosis, which then differentiate into spermatozoa.spermatozo´al

spermatozoon
[spur′mətəzō′ən, spərmat′-] pl. spermatozoa
Etymology: Gk, sperma + zoon, animal
a mature male germ cell that develops in the seminiferous tubules of the testes. Resembling a tadpole, it is about 50 μm (1/500 inch) long and has a head with a nucleus, a neck, and a tail that provides propulsion. Developed in vast numbers after puberty, spermatozoa are the generative component of the semen. See also spermatogenesis.
spermatozoon
pl. spermatozoa; a mature male germ cell, the specific output of the testes, which impregnates the ovum in sexual reproduction.
The mature sperm cell is microscopic in size. It looks like a translucent tadpole, and has a flat, elliptical head containing a spherical center section, and a long tail by which it propels itself with a vigorous lashing movement.

Patient discussion about Spermotozoa.
Q. What are some ways to get an erection? Libido and sperm are OK. I have had a problem with depression for years. I have always had a strong libido and I find that my ED has been a factor in my depression. Sexual relationships have helped me deal with my depression. What a MIRACLE! How can something so good be a remedy for mental problems. Oh! for a good stiff dick. I have considered a penile prosthesis implant but I'm still hoping for something better. Any information that might help would be greatly appreciated and I will remember you in my dreams and fantasies(sexual)for you ladies and I'll thank you studs. John
A. I am a female but my husband likes to think about a womans vagina. So maybe you should get a fake vagina try Adameve.com. And also try lubricants and other things, think about what turns you on.
Q. can hepatitis be transferred from fathers sperm when concieving a child? My partner has hepatitis C and he has gotten me pregnant will our baby have it too?
A. Here is taken from wikipedia (http://en.wikipedia.org/wiki/Hepatitis_C#Transmission) :
Sexual transmission of HCV is considered to be rare. Studies show the risk of sexual transmission in heterosexual, monogamous relationships is extremely rare or even null. The CDC does not recommend the use of condoms between long-term monogamous discordant couples (where one partner is positive and the other is negative). However, because of the high prevalence of hepatitis C, this small risk may translate into a non-trivial number of cases transmitted by sexual routes. Vaginal penetrative sex is believed to have a lower risk of transmission than sexual practices that involve higher levels of trauma to anogenital mucosa.
Mother-to-child transmission of hepatitis C has been well described, but occurs relatively infrequently. Transmission occurs only among women who are HCV RNA positive at the time of delivery; the risk of transmission in this setting is approximately 6 out of 100. Among women w

Q. how do i teat my no sperm count? i do not have a live sperm,how can i treat and have live sperm count
A. The treatment is done only at specialist centers, and consists first of evaluation of the reason for this condition (called azoospermia). If an anatomical malformation is found, it may be corrected, as well as medical conditions, and in some cases, direct extraction of sperms from the testes (called MESA) enables in-vitro fertilization.
