The authors reported that women with subclinical hypothyroidism who were 35 years or older had even lower ovarian reserves. In addition, these women had higher levels of FSH and even fewer aspirated oocytes that younger women with subclinical hypothyroidism.
Can thyroid affect FSH levels?
Thyroid health and fertility
An imbalance of these hormones affects ovulation and is a major cause of female fertility problems. Hypothyroidism can have a direct effect on these hormones: a deficiency in thyroxine leads to lower levels of FSH and LH in the blood.
Are TSH and FSH related?

Which hormone is elevated in hypothyroidism?
Hypothyroidism causes an increase in the levels of thyroid releasing hormone (TRH) which in turn stimulates secretion of thyroid stimulating hormone (TSH) and prolactin (PRL) and PRL inhibits the synthesis and secretion of gonadotrophins.

Can hypothyroidism cause poor egg quality?
7) Sub-Clinical Hypothyroidism Impacts Egg Quality
Sub-clinical hypothyroidism means that there are no symptoms. The only way of diagnosing this condition is with a blood test (TSH level). With elevated TSH levels, the quality of eggs retrieved is compromised. This results in lower pregnancy rates.
Does high prolactin affect FSH?
High prolactin levels inhibit secretion of FSH, which is the hormone that triggers ovulation. So, if your prolactin levels are high, your ovulation may be suppressed.
Can too much estrogen cause hypothyroidism?
Too much estrogen can also block the uptake of thyroid hormones, once again leading to symptoms of hypothyroidism. These symptoms often manifest most strongly during perimenopause, when progesterone levels are significantly decreased but estrogen is still present.
Does hypothyroidism cause hormonal imbalance?
When your thyroid produces too many or too few hormones, it can cause imbalances that are associated with a host of symptoms.
