, in biology, specialized plant or animal sex cell, also called the egg, or egg cell. It is the female sex cell, or female gamete; the male gamete is the sperm. The study of the ovum is included in the science of embryology.

In higher plants, sperms are nonmotile because they develop inside a pollen tube, which forms upon the germination of a pollen grain (microspore). Fertilization takes place after the pollen tube ruptures upon reaching the female sex organ—the archegonium in gymnosperms or the embryo sac in angiosperms. In gymnosperms a pair of sperms forms as a result of the division of the generative cell. One of the sperms participates in fertilization, and the other dies. Both sperms participate in the fertilization of angiosperms, one fertilizing the ovum, and the other the secondary nucleus of the embryo sac. The male gametes of pteridophytes, bryophytes, and some gymnosperms (including Cycadopsida and ginkgos) are called spermatozoids; they are flagellate and motile. sperm[spərm] (histology) spermatozoon sperm1. another name for semen2. a male reproductive cell; male gamete sperm

[G. sperma, seed]Patient discussion about spermQ. how do i teat my no sperm count? i do not have a live sperm,how can i treat and have live sperm countA. 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.

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.
