produced by the individual; also the category to which the individual fits on the basis of that criterion. Called also gender
. See also gender identity
and gender role
2. to determine which of these categories an organism belongs in.
the 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
endocrinologic sex the phenotypic manifestations of sex determined by endocrine influences, such as development of breasts and genital organs.
gonadal sex the sex as determined on the basis of the gonadal tissue present (ovarian or testicular).
glandular secretions involved in the regulation of sexual functions. The principal sex hormone in the male is testosterone
, produced by the testes. In the female the principal sex hormones are the estrogens
, produced by the ovaries. These hormones influence the secondary sex characters
, such as the shape and contour of the body, the distribution of body hair, and the pitch of the voice. The male hormones stimulate production of spermatozoa in men, and the female hormones control ovulation, pregnancy, and the menstrual cycle in women.
morphological sex sex determined on the basis of the morphology of the external genitals.
nuclear sex 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.
The biologic character or quality that distinguishes male and female from one another as expressed by analysis of the person's gonadal, morphologic (internal and external), chromosomal, and hormonal characteristics. Compare: gender
2. The physiologic and psychological processes within a person that prompt behavior related to procreation or erotic pleasure.
a. Sexual activity, especially sexual intercourse: hasn't had sex in months.
b. The sexual urge or instinct as it manifests itself in behavior: motivated by sex.
a. Either of the two divisions, designated female and male, by which most organisms are classified on the basis of their reproductive organs and functions: How do you determine the sex of a lobster?

4. One's identity as either female or male.
5. The genitals.
To determine the sex of (an organism).
The structural and functional characteristics of a person or organism that allow assignment as either male or female; sex is determined by chromosomes, hormones and external and internal genitalia (gonads).
The phenotypic (and psychosocial) expression of a person’s genotype, which defines a subject/patient in a clinical trial as male, female or other.
A person's self-image and mental status as male, female or uncertain. Depending on the circumstances, this determination may be based on the appearance of the external genitalia or on karyotyping.
One’s personal and reproductive status as male, female or uncertain, which is generally determined by the person’s internal and external genitalia.
Sexual activity or intercourse; genital interaction.
The biologic character or quality that distinguishes male and female from one another as expressed by analysis of the individual's gonadal, morphologic (internal and external), chromosomal, and hormonal characteristics.
2. The physiologic and psychological processes within an individual that prompt behavior related to procreation or erotic pleasure.
1. Gender, as genetically determined.
2. The condition of being male or female.
3. The urge or instinct manifesting itself in behaviour directed towards copulation.
4. The genitalia.
1. Biologic character or quality that distinguishes male and female from one another as expressed by analysis of person's gonadal, morphologic (internal and external), chromosomal, and hormonal characteristics.

Patient discussion about sex
Q. Is it safe to have sex with my pregnant wife? My wife and I are 4 months pregnant and are expecting our first baby. Can we have sex? I am afraid it will harm the baby.
A. Yes, sex is safe anytime during a normal pregnacy. Until her water breaks or the Doctor specifically tells you that you cannot have sex you can! I am happy to see you care about your wife and baby enough to ask!
Q. sex after giving birth My baby (Shelly) is three months now. Me and my husband tried having sex a couple of times since she was born, but the intercourse just hurts too much. Is this normal? I heard that sometimes when you get cuts during the birth they sew you too tight. Can it be the case? And if so, is this permanent or will it get better?
A. as long as the wound is already recovered, I think you can start the sexual activities. But again it depends on every person, I think scoote had given us a good example for that.
In case you still feel some discomfort and even hurt sensation down there, it is advisable to go see your doctor, just to check.
Meanwhile, enjoy your life and my greeting for baby Shelly..
Q. Is it safe to have sex with a woman with cancer of the uterus? My 45-years old wife was told she have cancer in the uterus, and will have an operation soon. Meanwhile, should we use a condom during sex? Can the tumor pass from her to me (like AIDS or HPV)?
A. unless the cancer has lots of bleeding, you don't need to use condoms.More discussions about sex
but if your wife would undergo an operation, maybe you need to be off-of-that-sex 1-2 days prior to operation day, just to make sure there's no super infection that will bother the operation plan.
