Absence Of Menstruation.
ORIGIN from Greek

Primary
Secondary

4. Events of Puberty
•1-Thelarche :
• the breast development
• Requires estrogenestrogen
•2-Pubarche/adrenarche :
pubic hair development
Requires androgensandrogens

5. Stage1 stage2
Prepupertal: elevation of
papilla- no pubic hair
Elevation of breast and papilla
on a small mount,increase in
areola – libial hair
Marshall and tunner staging

6. Stage 3 stage4
Further breast enlargment,
hair extend to mons pubis
Secondary mound of areola
and papilla ,hair extend
laterl
And increases pigmention

7. Stage5
Recession of arola to contour of the breast
Adult pubertal hair with striaght upper
borded

8. Requires:
GnRHGnRH from the hypothalamus
FSHFSH and LHLH from the pituitary
Estrogen and progesteroneEstrogen and progesterone from
the ovaries
Normal outflow tract

14. Common causes of Amenorrhea
Primary
• Gonadal failure (45%)
•Congenital absence of uterus and vagina (20%)
•Constitutional delay (15%)
Secondary
Chronic anovulation (40%)
•Hypothyroidism / hyperprolactinemia (20%)
•Weight loss/anorexia (16%)

15. Constitutional pubertal delay
• Common cause (15%)
Positive family history
• Under stature and delayed bone
age ( X-ray Wrist joint)
•• Diagnosis by exclusion and
follow up
• Prognosis is good(late developer)
• No drug therapy is required –
Reassurance (? HRT)

17. Evaluation Categories
•1-Breast Absent – Uterus Present
•2-Breast Present – Uterus Absent

19. Typical features of Turner Syndrome Turner Syndrome
1st commen cause (45% of causes )1st commen cause (45% of causes )

20. Turner's S.

22. •A craniopharyngioma is a benign tumor that
develops near the pituitary gland .
• most commonly in childhood and adolescence
and
•in later adult life.
compresses the pituitary stalk or gland, the tumor
can cause partial or complete pituitary hormone de
ficiency.

23. • Family history:Consider watchful waiting
• Request: FSH, LH
- Raised: Karyotype: 45 XO Turner syn
46 XX Premature ovarian failure
- Low: Constitutional delay
Consider:anorexia
exercise
illness
coeliac disease

- Intermediate: Anatomical - ultrasound

24. Mayer-R (okitansky-Kuster-Hauser
syndrome(

25. Utero-vaginal Agenisis
Mayer-Rokitansky-Kuster-Hauser syndrome
•Second most common cause of Primary
amenorrhea.
•Normal breasts and Sexual Hair Normal
looking external female genitalia
•Karyotype 46-XX
•15-30% renal abnormalities.
•Treatment : Vaginal creation
(Dilatation VS Vaginoplasty)

26. •Normal breasts but no sexual hair
•Normal looking female external genitalia
•Absent uterus and upper vagina
•Karyotype 46, XY
•Male range testosterone level
•Treatment : gonadectomy after puberty + HRT
Androgen insensitivity
Testicular feminization syndrome

27. • Absent/abnormal then karyotype:
- 46 XX Mullerian agenesis
- 46 XY Androgen insensitivity
• Present
•+ no outflow obstruction

28. 1-Rule out pregnancy!

29. 2-Exclude cryptomenohrea

30. ✴1-Pregnancy
✴2-Cryptomenorrhea :
imperforated hymen, vaginal septum,
✴3-Causes 2nd ry Amenorrhea :
hypothalamic, pituitary ,other endocrionpathy

31. Very rare

32. Compartment I: Disorders of the Outflow
Tract
•Eugonadism

33. MRI: complete low
transverse septum with
obstruction
MRI: complete slightly
higher transverse septum
with obstruction

35. Compartment II: Disorders of the Ovary
•Hypergonadotropic
hypogonadism

36. Compartment III: Disorders of
the Anterior Pituitary
•Hypogonadotropic hypogonadism

37. Microadenoma vs
macroadenoma

38. Compartment IV: Hypothalamic
(Kallmann’s syndrome)

•Hypogonadotropic
hypogonadism
•Congenital disorder characterized
by:
•1) Anosmia or hyposmia
•2) Primary amenorrhea
•Caused by defect in synthesis
and/or release of gonadorelin (LH
releasing hormone)

40. Secondary amenorrhea

41. In women of reproductive age,
pregnancy is the most common
cause of secondary amenorrhea.
Pregnancy
The reality of this must be
ascertained before any
intervention is instituted for non-
obstetric amenorrhea.

Anorexia nervosa
•A psychological disease
characterized by
•Intense fear of gaining weight or being fat,
despite being underweight

57. Step 2

58. •Asharman syndrome(intrauterine
synechea)

59. Step 3

60. Treatment
I.Treatment of the cause.
1-if Y chromosome is present gonadectomy is
indicated
2- Create outflow tract or at least a sexually functional
vagina
II. No obvious cause:
. Conception is not required: COCP.
. Conception is required: induction of ovulation
