sperm

 [sperm]
1. the semen or testicular secretion.

sperm

, pl.

sperms

(sperm),
The male gamete or sex cell that contains the genetic information to be transmitted by the male, exhibits autokinesia, and is able to effect zygosis with an oocyte. The human sperm is composed of a head and a tail, the tail being divisible into a neck, a middle piece, a principal piece, and an end piece; the head, 4-6 mcm in length, is a broadly oval, flattened body containing the nucleus; the tail is about 55 mcm in length.
Synonym(s): sperm cell, spermatozoon

sperm,

n the cells contained in the male's semen that fertilize the female's egg during the process of conception.

sperm

the male germ cell. See also spermatozoon.

sperm agglutinins
anti-sperm antibodies of the IgG class occur as autoantibodies in dogs infected with Brucella canis.
sperm capacitation
acquisition of the capacity to penetrate an ovum, not present at the time of delivery of the spermatozoon, and which requires a period of incubation in the female tract. It involves increased metabolic activity and motility and the removal of a chemical decapacitation factor from the spermatozoon. Capacitation must take place for the acrosome reaction to occur.
sperm concentration
a sperm count as measured in a hemocytometer; an indication of the health of the relevant testicles and a guide to the prospective fertility of the ejaculate and the donor.
sperm live-dead ratio
an indicator of the viability of the ejaculate as expressed in a slide count of a specially stained smear of the semen in which the dead and live sperm can be distinguished because of their differential staining.
sperm morphology
the normal anatomical structure of the spermatozoon. Abnormality of the structure of individual spermatozoa is used as a guide to the location and nature of the disease causing reduced reproductive efficiency.

sperm motility
the percentage of spermatozoa moving actively forward. Assessed under the microscope (400 × magnification) or by computerized imaging. See also wave motion; used to predict the probable fertility of the ejaculate.
sperm motility index
half the sum of the sample's sperm percentage motility + sperm progressive motility.
sperm penetration assay
see ovum penetration assay.
sperm stone
hard bodies composed of inspissated masses of spermatozoa found in dilated remnants of epididymal ducts and produced by chronic epididymitis.
sperm transport
within both male and female reproductive tracts some movement forward results from the movements of the spermatozoa but most progress is the result of peristaltic movements by the tubular organs in which the spermatozoa find themselves at the time.

Patient discussion about sperm

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.

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
