A young female presents to OPD with a spontaneous aboion and secondary amenorrhea since then. FSH was found to be 6 IU/mL. What is the most probable cause of amenorrhea?
Ovarian failure
Pituitary failure
Ongoing pregnancy
Uterine synechiae
* Since the lady is having secondary amenorrhea following an aboion, uterine synechiae is the most likely. Although uterine synechiae mostly develops with an overzealous curretage, it is also seen in spontaneous aboions. Also, here FSH levels are normal so it ours an end organ pathology. (Normal serum FSH value in adult woman is 5 - 20 lU/ml).* In case of ovarian failure - FSH will be high* In case of pituitary failure - Level of FSH is low.
