The reason for hormonal imbalance with higher male hormone is mostly due to polycystic ovarian disease( in your case given the history of prior delivery of normal child). This also comes in a way of conception since you are trying for months now. Get your TSH, LH, FSH, Prolactin
tests done from an NABL certified lab and get back to me with latest report of your ultrasound
pelvis also. I can guide you further over this.
Meanwhile try to lose weight if you are overweight
and start on folic acid supplement
as you are trying for conception. Take care.
