This thyroid gland is involved in almost every process including ovulation,menstrual irregularities and hormonal problems..When our thyroids are under active or overactive they tend to affect our other hormonal cycles. This thyroid hormone controls the basic female hormones estrogen and progesterone, which is important during pregnancy.
1)Hypothyroidism affects the production of the luteinizing hormone (LH), which stimulates the ovaries to release an egg. During normal ovulation,
more LH is produced, but when too little thyroid hormone is released, hormonal imbalances can prevent ovulation.
2)It also causes an increase in prolactin hormone, which is responsible for milk production. When the pituitary gland secretes too much prolactin, this can cause irregular menstrual cycles and prevent ovulation
3)When the thyroid gland is not functioning properly, ovarian cysts can also interfere with ovulation,
When the thyroid gland does not secrete enough thyroxine hormone (T4), treatment is necessary to bring hormone levels back to normal for conception.If you are hypo/hyper thyroid you must consult your doctor and be on your thyroid medicine.Once your levels are stabilized you can conceive without any problem.
