Male Sex Hormone Panel: Normal Reference Ranges
Men play an indispensable role in reproduction. Only when a man’s body maintains optimal health can a woman conceive normally. Male sex hormones are a critical parameter that must remain within normal ranges during the reproductive process. Below are the reference (normal) values for the six key male sex hormones:
Normal Reference Ranges for the Six Male Sex Hormones
1. Follicle-Stimulating Hormone (FSH): 1.27–12.96 mIU/mL
2. Luteinizing Hormone (LH): 1.24–8.62 mIU/mL
3. Estradiol (E2) in adult males: 20–75 pg/mL
4. Progesterone (P) in adult males: 0.10–0.84 ng/mL
5. Testosterone (T) in adult males: 20–756 ng/dL
6. Prolactin (PRL) in adult males: 2.64–13.13 ng/mL
Men undergoing infertility evaluation should undergo testing for these six sex hormones:
1. Luteinizing Hormone (LH): Measuring LH levels helps assess gonadal function and identify conditions such as hypogonadism, primary testicular failure, or impaired development of the seminiferous tubules. It also aids in diagnosing male infertility.
2. Prolactin (PRL): Elevated prolactin may indicate hypothalamic-pituitary dysfunction. Prolactinomas (pituitary adenomas) can cause hyperprolactinemia, which is associated with erectile dysfunction in men.
3. Estradiol (E2): Estradiol measurement helps diagnose gynecomastia or feminization syndromes in men. Abnormally elevated E2 levels may also suggest testicular cancer.
4. Follicle-Stimulating Hormone (FSH): FSH assessment is essential, as both azoospermia and oligospermia are closely linked to FSH levels. Abnormal FSH may reflect testicular dysfunction or incomplete development of the seminiferous tubules.
5. Progesterone (P): Although less commonly emphasized in male fertility assessments, progesterone testing may help evaluate adrenal or gonadal steroidogenesis and, in certain contexts, support the diagnosis of luteal-phase defects (though primarily relevant in females).
6. Testosterone (T): This test is crucial for diagnosing disorders of testicular function, including hypogonadism and androgen deficiency.
Men should abstain from smoking and alcohol consumption while attempting conception, as nicotine and alcohol significantly impair sperm quality. We hope this information is helpful!
