Characters discuss sex, infidelity, promiscuity, homosexuality, transsexuality, and masturbation between each other, sometimes in a medical context (this occasionally involves teens and children) or casually. These conversations are not graphic and at times comical. Prostitution is also mentioned as many patients (men and women, who are at times adolescents and even children) are said to be prostitutes.
Characters are occasionally seen kissing and making out
Characters flirt with each other throughout the show, this occasionally includes sexual innuendos
Medical procedures are done on certain patients' genitalia throughout the show. Nothing is ever seen other than the doctor's arms being in between the patient's legs or pictures being taken. This includes circumcisions, rape kit exams (at times done on cadavers and unconscious patients), pap smears, recovery of items stuck inside patients, abortions, and births. This sometimes involves teens and children. Pubic hair, ejaculation, penetration, erections, semen, and impotency are mentioned. Doctors sometimes go into detail and describe what is being done in medical terms.
There are scenes where sex is implied. For example, characters are seen next to each other in bed or kissing each other and undressing before the scene cuts away.
There are occasional sex scenes throughout, characters are sometimes heard moaning & panting (at times loudly and off-screen) and they are seen moving under some sheets and kissing each other. These scenes are usually brief and not graphic, at times we see the bare buttocks of some characters when getting out of bed, a woman's bare back, or the side of a woman's boobs. In some extremely rare instances, we see a woman's bare breasts, but very briefly and hard to see. Although some seasons don't have any sex scenes at all, some have multiple.
Male & female rear nudity is seen throughout the show, sometimes in a medical context or sexual context (characters getting out of bed after intercourse). This is usually brief, although there are some close-up shots in a few episodes.
