Testosterone is a key androgen that is essential for sexual development, reproduction, bone health, muscle development and red blood cell production. Abnormal levels can be assessed through blood tests, and normal values vary by gender and age. High testosterone may lead to risks such as prostate problems, reduced sperm count, virilizing characteristics, premature development, and female infertility, emphasizing the importance of maintaining appropriate testosterone levels. If you have any doubts, you should promptly consult a doctor for professional evaluation and management.
