hai, thyroxine plays major role in all our body function (body temperature regulation,metabolism,menstrual cycle etc..). in which lack of thyroxine (hypothyroidism) will cause irregular periods (mensuration cycle). when irregular period is persist that leads to infertility. and as from your quote it seems to be you got a poly cystic ovarian disease(PCOD). this is will also not allow the ovaries to function properly. ovulation will be disturbed. this will also lead to infertility. high Blood pressure also should be considered. consult your gynecologist to treat your bulky ovaries with Follicle. once you start treatment for bulky ovaries with follicle your periods will get normal,along with maintaining thyroxine level in normal limit will solve your infertility problem and you can have a baby. Thank you hope i answered your query.
