1. the fundamental distinction, found in most species of animals and plants, based on the type of gametes produced by the individual or the category to which the individual fits on the basis of that criterion. Ova, or macrogametes, are produced by the female, and spermatozoa, or microgametes, are produced by the male. The union of these distinctive germ cells results in the production of a new individual in sexual reproduction.
2. to determine the sex of an animal.

sex cell
see germ cell, gamete.
sex chromatin
the persistent mass of chromatin situated at the periphery of the nucleus in cells of normal females; it is the material of the inactivated sex chromosome. Called also Barr body.
chromosomal sex
sex as determined by the presence of the XX (female) or the XY (male) genotype in somatic cells, without regard to phenotypic manifestations. Called also genetic sex.
sex chromosomes
see sex chromosomes.
sex determination
1. the change in the fetus to a male or female configuration; the process by which the sex of an organism is fixed, associated, in animals, with the presence or absence of the Y chromosome.
2. diagnosis of the sex of the fetus before birth performed by examination of fetal fluids obtained by amniocentesis.
sex determining region of Y

the sex as determined on the basis of the presence or absence of sex chromatin in somatic cells, its presence normally indicating the XX (female) genotype, and its absence the XY (male) genotype.
sex parity
see sex ratio (below).
sex pheromone
sex ratio

sex reversal

Patient discussion about sex drive

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
