Hypogonadism occurs when the sex glands produce little to no sex hormones. These glands, known as gonads, are primarily the ovaries in females and the testes in males. Sex hormones play a critical role in the development of secondary sex characteristics, such as breast development in females and pubic hair growth in males. They also regulate the menstrual cycle and sperm production. Hypogonadism is also referred to as gonadal deficiency and can be called andropause or low serum testosterone when it occurs in males.

Types of Hypogonadism:
Primary Hypogonadism: This type occurs due to a problem in the gonads themselves, resulting in insufficient sex hormone production.
Secondary Hypogonadism: This form, also known as hypogonadotropic or central hypogonadism, originates in the hypothalamus or pituitary gland, which are responsible for signaling the gonads to produce hormones.

Symptoms of Hypogonadism:
In Females: Lack of menstruation, Slow or absent breast growth, Milky discharge from the breasts, Hot flashes, Loss of body hair, Low or absent sex drive, Infertility, Osteoporosis etc.
In Males: Reduced growth of the penis and testicles, Erectile dysfunction, Osteoporosis, Infertility, Fatigue, Hot flashes, Loss of body hair, Low or absent sex drive, Difficulty concentrating, Abnormal breast growth etc.
