FSH (follicle-stimulating hormone) is released by the pituitary gland in the brain to push the ovaries to develop follicles (the immature sacs that mature and release an egg when we ovulate) and produce oestrogen. As ovarian function naturally declines with age, oestrogen levels drop, and the pituitary gland recognises this and pumps out more FSH to try and get the ovaries to work harder so FSH usually rises in late perimenopause and postmenopause. However, this will not happen consistently in t

THESE MARKERS EXPLAINED…⬇️ 🧪TSH (Thyroid-Stimulating Hormone): TSH is produced by the pituitary gland and stimulates the thyroid gland to produce thyroid hormones (T4 and T3). Elevated TSH levels suggest an underactive thyroid (hypothyroidism), while low TSH levels indicate an overactive thyroid (hyperthyroidism). 🧪T4 (Thyroxine): T4 is a prohormone produced by the thyroid gland. T4 gets converted into the active form, T3, in the body. T4 levels are measured to assess thyroid function. 🧪T3 (T
