(redirected from Gonadotrophs)


1. a type of basophil in the adenohypophysis whose granules secrete follicle-stimulating hormone and luteinizing hormone.
2. a gonadotropic substance.

Special cells inside the pituitary known as gonadotrophs produce hormones (specifically gonadotropin-releasing hormone and luteinizing hormone, or LH) that control ovulation and fertility.
The researchers previously discovered that gonadotrophs harbor insulin receptors, but no one really knew what the effect of insulin on those receptors was.
The investigators focused on a class of pituitary cells called gonadotrophs, which secrete luteinizing hormone (LH), critical for ovulation and fertility.

However, it is tempting to speculate that the prolonged status of decreased E2 synthesis due to a lack of the substrate (T) evoked the desensitization of either hypothalamic gonadotropin-releasing hormone neurons or FSH-synthesizing gonadotrophs in the pituitary.
