Which hormone is known to cause ovulation?

1. Follicle Stimulating Hormone

2. Luteinizing Hormone

3. Testosterone

4. Oxytocin

The correct answer is: Luteinizing Hormone

Luteinizing Hormone, often referred to as LH, plays a crucial role in the reproductive system, particularly in the process of ovulation. In females, a surge in LH levels is what triggers the ovary to release a mature egg from the follicle during the menstrual cycle. This process is integral for reproduction, as the release of the egg makes it available for fertilization. In contrast, Follicle Stimulating Hormone (FSH) is primarily involved in the growth and maturation of ovarian follicles and does not directly cause ovulation. Testosterone is a hormone associated with male reproductive functions and secondary sexual characteristics, while oxytocin is mainly involved in childbirth and lactation, rather than the ovulation process. The specificity of luteinizing hormone in inducing ovulation makes it the correct answer to the question.
