In infertility evaluations, one essential test is quantifying LH levels in the body. The LH (Luteinizing Hormone) test is an endocrine test that helps doctors evaluate pituitary gland activity and reproductive function, thereby identifying the causes of infertility. Medic Sai Gon Diagnostic Clinic is a reputable LH testing center in Da Nang.
What is an LH Test?
LH (Luteinizing Hormone) is a sex hormone produced by the body’s pituitary gland. LH levels are closely tied to human fertility, playing a crucial role in regulating ovarian function in females and testicular function in males.
An LH test measures the concentration of LH in blood serum. It is considered one of the essential techniques for diagnosing infertility in both men and women, while also helping evaluate issues related to precocious (early) or delayed puberty in children.

Who Should Get an LH Test?
Typically, this test is performed under a doctor’s order during the evaluation and treatment of infertility. Both men and women may undergo LH testing to check their reproductive health or assess fertility issues, particularly in the following cases:
- Women experiencing irregular menstrual cycles, amenorrhea, or missed periods.
- Men experiencing reduced libido or low muscle mass, or those with lab results showing lower-than-normal testosterone levels.
- Individuals with pituitary disorders exhibiting symptoms such as fatigue, loss of appetite, unexplained weight loss, muscle weakness, etc.
- Couples dealing with infertility who are trying to conceive. Doctors will often order FSH and LH tests to accurately identify the timing of ovulation.
- Children experiencing precocious (early) or delayed puberty.
What is a Normal LH Level?
Normal LH concentrations vary depending on gender, age, and the phase of the menstrual cycle in women. The timing of the test is crucial for assessing whether hormone levels in the body fall within a normal or abnormal range.
Adult males: Approximately 1.7 – 8.6 IU/L.
Females:
- Follicular phase: Approximately 2.4 – 12.6 IU/L.
- Ovulation phase: Approximately 14 – 95.6 IU/L (LH surges to stimulate ovulation).
- Luteal phase: Approximately 1.0 – 11.4 IU/L.
- Postmenopausal: Approximately 7.7 – 58.5 IU/L.
Significance of LH Levels in Infertility Treatment
As established, LH plays a crucial role in the reproductive function of both men and women. In infertility evaluation and treatment, testing LH levels helps doctors assess endocrine health and pinpoint the underlying causes of difficulty conceiving.
In women: LH helps monitor follicular development and determine the precise timing of ovulation. A sudden spike in LH (the “LH surge”) signals that an egg is about to be released. This timing is vital for scheduling natural intercourse, intrauterine insemination (IUI), or egg retrieval for in vitro fertilization (IVF). Abnormally high or low LH levels may be linked to polycystic ovary syndrome (PCOS), ovarian insufficiency, or ovulatory disorders.
In men: LH stimulates the testes to produce testosterone. Abnormal LH concentrations can indicate testicular failure, endocrine dysfunction, or impaired spermatogenesis, which can lead to reduced sperm count and quality.
An LH test result is rarely evaluated in isolation. It is typically interpreted alongside clinical symptoms and a broader endocrine panel—including FSH, Estradiol (E2), Progesterone, and Testosterone—to provide the most accurate diagnosis.
