PROLACTIN

Prolactin is a polypeptide hormone with a molecular weight of 23 kDa which is secreted by the anterior pituitary gland. Prolactin levels increase during pregnancy and after birth. Mental and physical stresses and hypoglycemia increase prolactin levels. Increased levels of prolactin in women and men result in menstrual disorders and weakening of sexual power. Increased level of this hormone is common in hypothalamus and pituitary tumors, stress, excitement and nervousness, surgeries, primary hypothyroidism and... More...

LHTEINIZING (LH) is a glycoprotein with a molecular weight of 30 kDa which is secreted by the anterior lobe of pituitary. Secretion of this hormone is stimulated by the releasing hormone (GnRH) which is secreted by hypothalamus. LH levels in women change during menstruation, in the manner that its level is low in the beginning (follicular phase) and at the end of menstruation (luteal phase). Ovulation happens by the increase of this hormone in the middle of menstruation. In... More...

FSH

Follicle Stimulating Hormone (FSH) is a glycoprotein with a molecular weight of 30 kDa which is secreted by the anterior pituitary cells. Secretion of this hormone is stimulated by Gonadotropin releasing hormone (GnRH). This hormone is formed by two chains, namely alpha and beta. Alfa chain is structurally quite similar to those of other TSH،LH،HCG hormones. In women, at the beginning of menstruation (follicular phase), FSH causes the maturity of ovarian follicles by affecting them and ovulation occurs upon increase of FSH in the middle of menstruation. At the beginning of menstruation, FSH level is... More...

HCG is a glycoprotein hormone with a molecular weight of 46 kDa which is naturally secreted by placenta during pregnancy. This hormone is formed by two chains, namely alpha and beta. Alfa chain has a structure similar to those of other LH, TSH and FSH glycoprotein hormones. Level of this hormone in the blood increases rapidly with the onset of pregnancy and it reaches the highest level at the end of the first three months. This hormone can be evaluated within 8 to 11 days after fertilization (it reaches to an approximate level of 5 IU/L). HCG level is almost twice in twin pregnancies and it is unusually low in anomalies such... More...
