This category covers the hormones secreted by the testis and ovary, including their synthesis, regulation, and physiological roles in reproduction and secondary sexual characteristics.
Prolactin, secreted by the anterior pituitary, stimulates milk production in lactating mothers.
Ref: NCERT Class 11 Biology Chapter 19: Chemical Coordination and Integration Gonads - Testis and Ovary Hormones
Progesterone is secreted by the corpus luteum and is essential for maintaining the uterine lining during pregnancy.
Ref: NCERT Class 11 Biology Chapter 19: Chemical Coordination and Integration Gonads - Testis and Ovary Hormones
During pregnancy, the placenta secretes progesterone, which helps maintain the uterine lining.
Ref: NCERT Class 11 Biology Chapter 19: Chemical Coordination and Integration Gonads - Testis and Ovary Hormones
Testosterone, secreted by the testes, promotes the development of male secondary sexual characteristics.
Ref: NCERT Class 11 Biology Chapter 19: Chemical Coordination and Integration Gonads - Testis and Ovary Hormones
Luteinizing hormone (LH) stimulates ovulation by triggering the release of the mature egg from the ovary.
Ref: NCERT Class 11 Biology Chapter 19: Chemical Coordination and Integration Gonads - Testis and Ovary Hormones
Estrogen, secreted by the ovaries, regulates the female reproductive cycle and secondary sexual characteristics.
Ref: NCERT Class 11 Biology Chapter 19: Chemical Coordination and Integration Gonads - Testis and Ovary Hormones
Cortisol increases blood sugar levels by stimulating gluconeogenesis in the liver.
Ref: NCERT Class 11 Biology Chapter 19: Chemical Coordination and Integration Gonads - Testis and Ovary Hormones
Progesterone prevents uterine contractions and helps maintain pregnancy.
Ref: NCERT Class 11 Biology Chapter 19: Chemical Coordination and Integration Gonads - Testis and Ovary Hormones
Prolactin, secreted by the anterior pituitary, stimulates milk production in the mammary glands after childbirth.
Ref: NCERT Class 11 Biology Chapter 19: Chemical Coordination and Integration Gonads - Testis and Ovary Hormones
Progesterone, secreted by the ovaries, regulates the menstrual cycle and supports pregnancy.
Ref: NCERT Class 11 Biology Chapter 19: Chemical Coordination and Integration Gonads - Testis and Ovary Hormones
Oxytocin, secreted by the posterior pituitary, stimulates uterine contractions during childbirth.
Ref: NCERT Class 11 Biology Chapter 19: Chemical Coordination and Integration Gonads - Testis and Ovary Hormones
Estrogen is responsible for the development of female secondary sexual characteristics.
