Data was analyzed from the Australian Study of Health and Relationships, a national telephone survey of sexual behavior and attitudes and sexual health knowledge carried out in 2001–2002, with a representative sample of 19,307 Australians aged 16 to 59. Practices included "vaginal intercourse alone (12%), vaginal + manual stimulation of the mans and/or womans genitals (49%), and vaginal intercourse + manual + oral (32%)" and the "[e]ncounters may also have included other practices. Men had an orgasm in 95% of encounters and women in 69%. Generally, the more practices engaged in, the higher a womans chance of having an orgasm. Women were more likely to reach orgasm in encounters including cunnilingus".Other studies suggest that women exposed to lower levels of prenatal androgens are more likely to experience orgasm during vaginal intercourse than other women. Exercise-induced
Kinsey, in his 1953 book Sexual Behavior in the Human Female, stated that exercise could bring about sexual pleasure, including orgasm. A review in 1990 on the sexual response itself as exercise, reviewed the literature and stated that the field was poorly researched; it also said that studies had found that aerobic or isotonic exercise that resembles sexual activity or sexual positions can induce sexual pleasure, including orgasm. A 2007 review of the relationship between pelvic floor dysfunction and sexual problems in men and women found that they are commonly linked and suggested that physical therapy strengthening the pelvic floor could help address the sexual problems but that it was not well studied enough to recommend.
Teratomas of embryonal origin are most often found in babies at birth, in young children, and, since the advent of ultrasound imaging, in fetuses. The most diagnosed fetal teratomas are sacrococcygeal teratoma (Altman types I, II, and III) and cervical (neck) teratoma. Because these teratomas project from the fetal body into the surrounding amniotic fluid, they can be seen during routine prenatal ultrasound exams. Teratomas within the fetal body are less easily seen with ultrasound;  for these, MRI of the pregnant uterus is more informative. Complications
Teratomas are not dangerous for the fetus unless either a mass effect occurs or a large amount of blood flows through the tumor (known as vascular steal). The mass effect frequently consists of obstruction of normal passage of fluids from surrounding organs. The vascular steal can place a strain on the growing heart of the fetus, even resulting in heart failure, thus must be monitored by fetal echocardiography. Teratomas can cause an autoimmune illness called  N-methyl-D-aspartate (NMDA) receptor encephalitis. In this condition, the teratomas may contain B cells with NMDA-receptor specificities.After surgery,  a risk exists of regrowth in place, or in nearby organs. Pathophysiology
Teratomas belong to a class of tumors known as nonseminomatous germ cell tumor. All tumors of this class are the result of abnormal development of pluripotent cells: germ cells and embryonal cells. Teratomas of embryonic origin are congenital; teratomas of germ cell origin may or may not be congenital.
