Specific Causes of Amenorrhea
Specific Causes of Amenorrhea
Disorders of the Genital Outflow Tract and
UterusDisorders of The Ovary
Disorders of the Genital Outflow Tract and Uterus
As a cause of amenorrhea, disorders of the genital outflow tract and uterus are uncommon
Congenital developmental anomalies of the genital outflow tract and uterus result from the failure of vertical fusion of vertical fusion or from failure of mullerian duct development
Disorders of the Genital Outflow Tract and Uterus
Imperforate Hymen
Transverse Vaginal Septum/Cervical Atresia
Mullerian Agenesis
AIS
Cervical Stenosis
Asherman Syndrome
Imperforate Hymen
Typically, patients with an imperforate hymen present with complaints of cyclic perineal, pelvis, or abdominal pressure or pain that result from cryptomenorrhea
The genital examination reveals no obvious vaginal orifice and a thin, often bulging, blue perineal membrane at the inferior limit of palpable, fluctuant mass (hematocolpos)
Imperforate Hymen
The treatment of women with an imperforate hymen centers on providing relief of symptoms related to accumulated menstrual fluid and debris
Definitive surgery should be accomplished as soon as possible
Transverse Vaginal Septum/Cervical Atresia
Girls with transverse vaginal septum/cervical atresia generally present with complaints of cyclic pelvis or abdominal pain
Physical examination reveals a normal vaginal orifice, a shortened vagina of varying length, no visible cervix, and a palpable hematocolpos in the proximal vagina segment above the obstruction and/or a pelvic mass resulting from hematometra and hematosalpinges
Transverse Vaginal Septum/Cervical Atresia
In all instances, every effort should be made to incise and drain the sequestered menstrual fluid from below
The surgical management of a transverse vaginal septum can be challenging
The best surgical management for cervical atresia is controversial
Mullerian Agenesis
Patients with mullerian agenesis exhibit normal, symmetrical breast and pubic hair development, no visible vagina, and have no symptoms or signs of cryptomenorrhea because the rudimentary uteri contain no functional endometrium
Two form of the disorder have been describes Type A and Type B
Mullerian Agenesis
Progressive vaginal dilatation appropriate and effective first choice creation of a functional vagina
Operative treatment of mullerian agenesis generally can be reserved for those who are unable or unwilling to dedicate themselves to a program of progressive vaginal dilatation and for those in whom earnest efforts fail MacIndoe procedure and Vecchietti operation
Androgen Insensitivity Syndrome
Patients with complete AIS exhibit asymmetrical secondary sexual development, a short vagina with no visible cervix, and have no other symptoms or complaints
Patients with incomplete AIS have a greater sensitivity to androgen pubic hair growth may accompany breast development and the clitoris may enlarge
Androgen Insensitivity Syndrome
The treatment of patients with complete AIS has two major components, one focusing on creation of a functional vagina, and another relating to the risk for developing malignancy in the cryptorchid testes
Complete AIS is the only exception to the rule that gonads with a Y chromosome should be removed as soon as diagnosis is made
Cervical Stenosis
Severe cervical stenosis with complete outflow obstruction is a rare complication of cervical conization procedure or other surgical treatments for CIN
The treatment for cervical stenosis is careful dilatation
Asherman Syndrome
Although Asherman Syndrome from any cause may result in amenorrhea, most women with intrauterine adhesions present with dysmenorrhea, hypomenorrhea, infertility, or recurrent pregnancy loss, rather than amenorrhea
Asherman Syndrome
Operative hysterescopy is the primary method for treatment of intrauterine adhesions that may be lysed by scissors, electrodissections, or with a laser
Disorders of the Ovary
Disorders of the ovary include the most common causes of amenorrhea and can present as primary or secondary amenorrhea
Disorders of the Ovary
Gonadal dysgenesis
Turner Syndrome
Swyer Syndrome
46,XY Gonadal Dysgenesis
Gonadal Dysgenesis
The most common causes of primary amenorrhea
By far, the most common form of gonadal dysgenesis is Turner Syndrome
Turner Syndrome
Patients with Turner Syndrome generally present with primary amenorrhea and absent secondary sexual development
Approximately 15% of patients with Turner Syndrome begin but do not complete pubertal development and approximately 5% complete puberty and begin menstruation
Turner Syndrome
Treatment with estrogen must be timed carefully, with goals of minimizing its adverse effects and inducing puberty at an approximately normal age the goal of completing sexual maturation over a period of 2-3 years
Swyer Syndrome (46,XY Gonadal Dysgenesis)
Patients with Swyer Syndrome generally present with delayed sexual maturation and primary amenorrhea
Gonadectomy is indicated soon after diagnosis due to the significant risk for malignant transformation in occult testicular elements
The same sequential sex steroid treatment regimen for patients with Turner Syndrome can be applied for patients with Swyer syndrome
46, XX Gonadal Dysgenesis
Some individuals with primary amenorrhea and gonadal dysgenesis have a normal 46,XX karyotype autosomal genes also play a critical role in ovarian differentiation
