Amenorrhea:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
Amenorrhea is normal before puberty, after menopause, or during pregnancy and lactation; it’s pathologic at any other time. It usually results from anovulation due to hormonal abnormalities, such as decreased secretion of estrogen, gonadotropins, luteinizing hormone, and follicle-stimulating hormone; lack of ovarian response to gonadotropins; or constant presence of progesterone or other endocrine abnormalities.
Amenorrhea may also result from the absence of a uterus, endometrial damage, or from ovarian, adrenal, or pituitary tumors. It’s also linked to emotional disorders and is common in patients with severe disorders, such as depression and anorexia nervosa. Mild emotional disturbances tend merely to distort the ovulatory cycle, while severe psychic trauma may abruptly change the bleeding pattern or may completely suppress one or more full ovulatory cycles. Amenorrhea may also result from malnutrition, intense exercise, and prolonged hormonal contraceptive use. The incidence of primary amenorrhea in the United States is less than 1%. The incidence of secondary amenorrhea (due to some other cause than pregnancy) is about 4%.

Ectopic pregnancy:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
Conditions that prevent or retard the fertilized ovum’s passage through the fallopian tube and into the uterine cavity include:
❑ diverticula, the formation of blind pouches that cause tubal abnormalities
❑ endometriosis, the presence of endometrial tissue outside the lining of the uterine cavity
❑ endosalpingitis, an inflammatory reaction that causes folds of the tubal mucosa to agglutinate, narrowing the tube
❑ pelvic inflammatory disease (PID), an infection of the oviducts and ovaries with adjacent tissue involvement
❑ previous surgery (tubal ligation or resection, or adhesions from previous abdominal or pelvic surgery)
❑ tumors pressing against the tube.
Ectopic pregnancy may result from congenital defects in the reproductive tract or ectopic endometrial implants in the tubal mucosa. The increased prevalence of sexually transmitted tubal infection may also be a factor. In whites, it occurs in 1 in 200 pregnancies; in nonwhites, in 1 in 120.

About prevalence and incidence statistics:
The term 'prevalence' of Ectopic pregnancy usually refers to the estimated population
of people who are managing Ectopic pregnancy at any given time.
The term 'incidence' of Ectopic pregnancy refers to the annual diagnosis rate,
or the number of new cases of Ectopic pregnancy diagnosed each year.
Hence, these two statistics types can differ:
a short-lived disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
