The first step in the evaluation of any patient with secondary amenorrhea is a urine pregnancy test. Every contraceptive method has a failure rate, and anyone who is menstruating is potentially fertile, regardless of age. [5][6]
If the pregnancy test is negative, consider the clinical picture: hirsutism, acne, and a long history of infrequent and irregular menses suggest polycystic ovarian syndrome. By the Rotterdam criteria, a patient may be diagnosed with PCOS if she has two of the following: clinical or chemical hyperandrogenism, oligo- or amenorrhea, or polycystic ovaries on ultrasound. So if a patient has evidence of hirsutism and oligo- or amenorrhea, she can be diagnosed with PCOS without further laboratory testing or imaging.
If history and physical exam are not consistent with PCOS, a TSH should be ordered. Both hyper- and hypothyroidism can lead to menstrual dysfunction.
If TSH is normal, check a serum prolactin. Elevated serum prolactin suggests prolactinoma.

3. AMENORRHOEA
• Amenorrhea is classified as either primary or secondary.
• Primary amenorrhea is the lack of menstruation by the
age of 16yrs in the presence of normal development of
secondary sexual characters.
• Secondary amenorrhea is the absence of menstruation
for 6 consecutive months after menarche or in a woman
who has had a normal menstrual cycle.
• In a woman of childbearing age, the most common causes
of absent menstrual periods are pregnancy and lactation
4. Etiology
• There are three general causes of secondary
amenorrhea:
• Hormonal disturbance leading to a lack of a
normal menstrual cycle,
• Physical damage to the endometrium which
prevents its growth, or
• Obstruction of the outflow path of the
menstrual blood.
5. Pathophysiology
• Many potential causes of secondary amenorrhea.
• Hormonal causes include pregnancy, lactation, thyroid
dysfunction, hyperprolactinemia, hyperandrogenism
(including polycystic ovarian syndrome), hypogonadotropic
hypogonadism (hypothalamic-pituitary dysfunction), and
suppression of the endometrium by hormonal birth control.
• Structural causes include damage to the endometrium
(Asherman’s syndrome) and obstruction of the outflow tract
(cervical stenosis).
6. • Epidemiology
• Pregnancy, lactation,
and menopause are
common, physiologic
causes of secondary
amenorrhea.
• Prevalence of secondary
amenorrhea due to all
other causes is
approximately 2% - 5%
7. Spontaneous, cyclic menstruation requires an intact and
functional hypothalamic-pituitary ovarian axis
(HPOA),endometrium and genital outflow tract.
Abnormalities in any of these structures may result in
amenorrhea
10. 1.Hypothalamus
• Changes in GnRH signaling from the
hypothalamus to the pituitary can
disrupt this communication and
cause low gonadotropin (LH and FSH)
secretion and secondary amenorrhea
• Isolated deficit of gonadotropins
represent a rare cause of
hypothalamic amenorrhea, including
the Kallman syndrome and the
idiopathic hypogonadotropic
hypogonadism
11. • A common condition that results from disruption in this
process is functional hypothalamic amenorrhea (FHA),
which accounts for approximately 35% of all pathologic
secondary amenorrhea
• FHA is caused by stress from events such as severe
restrictive dieting, poor nutritional status, extreme
psychological stress, or excessive exercise.
• Recently genetic mutations have been associated with
FHA
• Less commonly, infiltrative diseases of hypothalamus
such as lymphoma, sarcoidosis or Langerhans cell
histiocytosis can interfere with hypothalamic function
12. PITUITARY GLAND
• The pituitary gland responds to GnRH signaling to
produce LH and FSH (also in a pulsatile fashion)
• Any change in the secretion of pituitary hormones can
lead to sec amen eg hyperprolactinaemia
• even a small change in prolactin may be sufficient to
change the menstrual pattern.
• Elevated prolactin levels should also prompt a check of
thyroid function because hypothyroidism can cause
hyperprolactinemia
13. PITUITARY GLAND
• An intact stalk is necessary for transmitting inhibitory signals to
the prolactin-secreting cells to prevent secretion. When normal
“tonic” inhibition is lifted by stalk compression, the pituitary
gland produces more prolactin. A common cause of stalk
compression is a pituitary adenoma.
• Any structural lesion in or near the pituitary gland can cause a
modest elevation in prolactin. When prolactin levels are
elevated (2 to 10 times normal), this usually indicates a
prolactin-lactotroph-secreting pituitary adenoma
14. PITUITARY GLAND
• Amenorrhea occurs when the process disrupts pituitary
function and results in decreased gonadotropin secretion
• Pituitary infarction can cause amenorrhea and sheehan
syndrome is a result of pituitary infarction following
postpartum hemorrhage or severe hypotension
• Results in partial or total loss of hormone secretion
• Can cause various endocrine deficiencies, such as
hypogonadotropic hypogonadism (loss of lh and fsh
secretion);secondary hypothyroidism (loss of thyroid-
stimulating hormone [tsh] secretion); and secondary
adrenal insufficiency (loss of adrenocorticotropic
hormone secretion).
15. 3 OVARIES
• PCOS is the most common endocrine disorder in women of
reproductive age, occurring in 7% to 10% of all young
women.
• It is characterised by altered FSH:LH ratio
• Hyperandrogenism
• Increased insulin resistance
• increased risk for prediabetes, type 2 diabetes mellitus
(T2DM), metabolic syndrome, fatty liver disease, and
obstructive sleep apnea
16. OVARIES
• When menopause or spontaneous loss of ovarian function
occurs prior to age 40, it is called spontaneous primary ovarian
insufficiency (POI), formerly referred to as premature ovarian
failure.
• Spontaneous POI is characterized by permanent cessation of
ovulation and menstruation. It can be idiopathic, a result of
prior surgery or chemotherapy, or a result of an autoimmune
process.
• FSHwill be elevated (greater than 30 to 40 IU/L) with low
estradiol levels (usually below 30 pg/mL)
• rare causes-Turner syndrome (lack of a second X chromosome),
fragile X syndrome, radiation to the pelvis, and a history of
mumps or cytomegalovirus.
17. 4. Uterus
• A less common cause of amenorrhea is Asherman
syndrome, which is fibrosis of the endometrium and
resulting lack of regeneration that leads to amenorrhea.
This can occur after instrumentation of the uterine cavity,
such as uterine curettage, myomectomy, cervical biopsy, or
polypectomy or insertion of an intrauterine device (IUD).
• More recently, therapeutic endometrial ablation has been
known to cause sec amen
21. HISTORY
Menstrual Cycle – Age of Menarche & Previous Menstrual History
Previous Pregnancies – Severe PPH( Sheehan’s Syndrome )
Weight Change – Excessive Weight Loss
Hot Flushes, Decreased Libido – Premature Menopause
Certain Medications
Contraception
Associated Symptoms – Cushing’s Disease, Hypothyroidism
Previous Gynaecological Surgery
Chronic illness
22. HISTORY. . .
• Review the menstrual intervals since menarche, and note
when any changes may have occurred along with any
other changes in medical history, social history,
medications, or weight that may have coincided with a
change in the menstrual pattern.
• Some women may consider “spotting” to be a normal
menstrual cycle, so ascertaining typical menstrual flow is
also important.
• Pregnancy and lactation
23. HISTORY
• Social and weight history
• any behaviors consistent with eating disorders or
excessive focus on weight and exercise. This would
include history of severe caloric restriction, laxative or
diuretic use, extreme and prolonged exercise regimens,
or evidence of obsession with weight/exercise
• Psychological stressors may include domestic violence
and/or a history of sexual or psychological trauma.
Health stressors could include severe or life-threatening
illness or injuries, noting the relationship of these events
to any change in the menstrual cycle or amenorrhea.
24. EXAMINATION
GENERAL EXAMINATION
•Nutritional Status
•Extreme Emaciation Or Marked Obesity
•Presence Of Acne Or Hirsutism
•Discharge Of Milk From Breasts
ABDOMINAL EXAMINATION
• Presence Of Striae Associated With Obesity May be related to
Cushing’s Disease
• A Mass In The Lower Abdomen.
PELVIC EXAMINATION
• Enlargement of Clitoris
• Adnexal Mass Suggestive Of Tubercular tubo-ovarian mass or
ovarian tumor

• endometrial lining,
• including thickening of the lining
(indicating lack of adequate
endometrial shedding)
• or absence of lining, as seen in
FHA or Asherman syndrome.
• diagnosis of PCOS,
30. DIAGNOSTIC APPROACH
• It is important to correlate hyperandrogenism with the
physical exam. If the patient has significant hirsutism,
persistent adult acne, or male pattern scalp hair loss, there
is strong positive evidence for clinical hyperandrogenism
and supports suspicion for PCOS or other androgen excess
disorders
31.
32. Treatment / Management
Treatment depends on the underlying cause of the
amenorrhea
• Polycystic ovarian syndrome is treated with weight loss
• Metformin for insulin resistance, and
• Cycle control with combined oral contraceptives or endometrial protection with
progestin-containing birth control methods (medroxyprogesterone acetate depot
injection, etonogestrel subcutaneous implant, or levonorgestrel intrauterine
system).
• Hypothyroidism is treated with thyroxine replacement.
• Hyperthyroidism is treated with thioamides, ablation, or surgery.
• Hyperprolactinemia is treated with bromocriptine, cabergoline, or excision of
prolactinoma.
• Ovarian failure may be treated with hormone replacement, depending on the
patient’s age, symptoms, and other risk factors.
• Hypothalamic-pituitary dysfunction may be treated with lifestyle changes or with
hormone replacement.
• Asherman’s syndrome is treated with hysteroscopic lysis of adhesions.
• Cervical stenosis is treated with cervical dilation.
