What Are Essential Fertility Hormones for Women? Ideal Levels & Testing Guide

Understanding Fertility Hormones: A Key to Reproductive Health

Hormones play a crucial role in female fertility, influencing ovulation, menstrual cycles, and overall reproductive health. Understanding these hormones and their ideal ranges can help women assess their fertility status and make informed decisions about family planning.

At Kind Fertility, we offer an at-home blood test for fertility to help women check their fertility status easily and accurately.

Key Fertility Hormones and Their Optimal Ranges

1. Anti-Müllerian Hormone (AMH)

• What It Does: AMH is a key indicator of ovarian reserve (the number of eggs remaining in the ovaries). Higher levels suggest a good egg reserve, while lower levels indicate diminished fertility.

• Ideal Range: 1.0 - 4.5 ng/mL (varies with age)

• When to Test: Anytime during the menstrual cycle

  
  

AMH Levels by Age:

• Under 25: Good AMH level is 4.1 ng/mL, and normal range is 2.5–6.0 ng/mL

• 25–29: Good AMH level is 3.5 ng/mL, and normal range is 2.0–5.5 ng/mL

• 30–34: Good AMH level is 2.8 ng/mL, and normal range is 1.5–4.5 ng/mL

• 35–39: Good AMH level is 1.5 ng/mL, and normal range is 1.0–3.0 ng/mL

  
  

2. Follicle-Stimulating Hormone (FSH)

• What It Does: FSH helps stimulate the growth of ovarian follicles, which house the eggs. High FSH levels may indicate poor ovarian function.

• Ideal Range: 3 - 10 mIU/mL (on Day 3 of the cycle)

• When to Test: Day 2-4 of the menstrual cycle

  
  

3. Luteinizing Hormone (LH)

• What It Does: LH triggers ovulation and regulates the menstrual cycle.

• Ideal Range: 1.9 - 12.5 mIU/mL (during the follicular phase)

• When to Test: Day 2-4 of the cycle; a surge indicates ovulation

  
  

4. Estradiol (E2)

• What It Does: Estradiol (a form of estrogen) supports the development of eggs and prepares the uterine lining for pregnancy.

• Ideal Range: 25 - 75 pg/mL (on Day 3 of the cycle)

• When to Test: Day 2-4 of the cycle

  
  

5. Progesterone

• What It Does: Progesterone stabilizes the uterine lining for implantation and supports early pregnancy.

• Ideal Range: Less than 1 ng/mL (before ovulation), 10+ ng/mL (after ovulation)

• When to Test: Around Day 21 of a 28-day cycle

  
  

6. Prolactin

• What It Does: Prolactin helps regulate ovulation and menstrual cycles; high levels may indicate hormonal imbalances affecting fertility.

• Ideal Range: 2 - 25 ng/mL

• When to Test: Early morning, preferably fasting

  
  

7. Thyroid-Stimulating Hormone (TSH)

• What It Does: TSH regulates thyroid function, which influences menstrual cycles and ovulation.

• Ideal Range: 0.5 - 4.5 mIU/L

• When to Test: Anytime, preferably in the morning

Why Hormone Testing Matters for Fertility

• Identifies potential fertility issues early

• Helps tailor fertility treatments like IVF or egg freezing

• Supports overall reproductive health
