Traumatic hypomenorrhea-amenorrhea (Asherman's syndrome)

Area of Science:

• Reproductive Medicine
• Gynecology
• Surgical Pathology

Background:

• Asherman's syndrome is characterized by uterine adhesions and/or cervical stenosis, often resulting from trauma.
• These conditions can lead to hypomenorrhea (infrequent menstruation) or amenorrhea (absent menstruation).

Purpose of the Study:

• To investigate the correlation between the severity of menstrual insufficiency and the extent of corporeal adhesions in Asherman's syndrome.
• To elucidate the pathophysiological mechanisms underlying menstrual abnormalities in Asherman's syndrome.

Main Methods:

• Correlation analysis between menstrual insufficiency severity and extent of corporeal adhesions.
• Radiologic studies to diagnose cervical stenosis or atresia.
• Clinical observation of menstrual restoration after cervical dilatation.

Main Results:

• A strong correlation exists between the severity of menstrual insufficiency and the extent of uterine adhesions.
• Minor adhesions in the lower uterine cavity can cause severe hypomenorrhea, sometimes with dysmenorrhea.
• Secondary amenorrhea can result from uterine cavity obliteration or internal os stenosis/atresia, with continued ovarian function but endometrial unresponsiveness.

Conclusions:

• Menstrual insufficiency in Asherman's syndrome is attributed to reduced endometrial bleeding area and endometrial unresponsiveness.
• Endometrial unresponsiveness may stem from trophic changes possibly induced by a visceral reflex from the internal os.
• Simple cervical dilatation effectively restores menstruation in cases of cervical stenosis or atresia.
