Testosterone replacement therapy: Testosterone replacement therapy, also known as androgen replacement therapy, is used to treat low levels of testosterone. Testosterone is the anabolic steroid and primary sex hormone in males, which plays an important role in the development of male reproductive tissues like the prostate and testes. Symptoms of low testosterone include reduced sex drive, erectile dysfunction, low/zero sperm count, loss of pubic/armpit hair, shrinking testicles, and hot flushes.

Primary hypogonadism: Primary hypogonadism is a condition in which the gonads (testes in men and ovaries in women) produce insufficient sex hormones. Sex hormones are responsible for secondary sexual characteristics, such as testicular development in men and breast development in women. Autoimmune disorders, genetic disorders, severe infections, pituitary disorders, and inflammatory diseases could be the causes of hypogonadism. Symptoms of hypogonadism include abnormal breast growth, erectile dysfunction, muscle loss, loss of body hair, osteoporosis, low sex drive, infertility, fatigue, hot flushing, and difficulty concentrating.

Hypogonadotropic hypogonadism: It is a form of hypogonadism that occurs due to a problem with the hypothalamus or pituitary gland. It is caused due to lack of the gonadotropin-releasing hormone, follicle-stimulating hormone (FSH), and luteinising hormone (LH). Damage to the pituitary gland, genetic defects, high prolactin levels, severe stress, nutritional problems, and certain medical conditions could be the causes of hypogonadotropic hypogonadism.
