FSH, LH &Prolactin

The Hormonal Profile Test, encompassing Follicle-Stimulating Hormone (FSH), Luteinizing Hormone (LH), and Prolactin, assesses the levels of key hormones that help regulate reproductive functions and lactation. The test is vital for detecting and monitoring hormonal disorders and fertility issues.

FSH, LH, and prolactin are all produced in the anterior pituitary gland and play vital roles in reproductive health and overall well-being. Assessing their levels with this hormonal panel is often the first step in determining fertility in both men and women.

FSH is crucial for the development of eggs, regulation of menstrual cycles in females, and sperm production in males. LH encourages the release of an egg from the ovary in females and stimulates testosterone production in males. Abnormal levels of FSH and LH can indicate menstrual irregularity, fertility issues, and conditions such as polycystic ovary syndrome (PCOS) and pituitary disorders.

Prolactin is a hormone that stimulates breast development and milk production (lactation) in females. Additionally, it also influences the menstrual cycle. Elevated prolactin levels can interfere with fertility, cause menstrual irregularities, and be associated with conditions such as galactorrhea (inappropriate milk production) and pituitary tumors (prolactinomas).

In women, the doctor may suggest this test in case of symptoms of irregular or heavy menstrual periods, PCOS/PCOD, if you are facing difficulty in getting pregnant, and/or if pituitary or hypothalamus problems are suspected. In men, this test can be performed when fertility issues and signs of low testosterone levels, such as decreased sex drive and low muscle mass, are observed. 

Overnight fasting is required for this hormonal profile. Do not eat or drink anything other than water for 8-12 hours before the test. In women, the preferred time to collect the sample is the second or third day of the menstrual cycle. Your doctor may ask you to temporarily stop taking certain medications, such as birth control pills or Biotin (Vitamin B7) supplements, as they may lead to some aberrancy in your test results. Prolactin levels can vary throughout the day as prolactin is secreted episodically and may be influenced by factors such as stress, exercise, and sleep. Therefore, multiple prolactin tests may be needed to confirm the diagnosis.

Test result ranges are approximate and may differ slightly between labs depending on the methodology and laboratory guidelines. Talk to your doctor about your specific test results. The results will help them determine your medical condition and formulate your treatment plan.
