Fertility Tests in California

Fertility tests are blood tests that check hormones and other markers linked to the ability to conceive. They are often ordered when a person or couple has trouble getting pregnant, or to evaluate menstrual, ovulation, or sperm-related concerns. Results help a clinician look for possible causes and plan next steps.

What it measures

FSH (follicle-stimulating hormone) — Helps control egg growth in women and sperm production in men.
LH (luteinizing hormone) — Triggers ovulation and supports hormone production.
Estradiol — A form of estrogen made mainly by the ovaries.
Progesterone — Rises after ovulation and helps confirm that ovulation occurred.
Testosterone — A hormone important for sperm production and male traits.
Prolactin — A pituitary hormone that can affect fertility when high.

Who it is for

A primary care clinician, gynecologist, urologist, or fertility specialist typically orders these tests. They may be ordered for one partner or both.

Preparation

Preparation depends on which hormones are checked. Some tests need a specific day of the menstrual cycle or a morning draw; fasting is often not required. Follow the instructions given by your clinician or lab.

Results and what they mean

Results are reported as numbers with reference ranges, and timing matters, so a clinician interprets them alongside your history. One abnormal value does not confirm a diagnosis. This is general information, not medical advice; discuss your results with a qualified clinician.

Requesting the Fertility Tests in California

Order online, choose a certified collection site in California, and review results through a secure portal. No referral is required, and orders are processed confidentially. With coastal metros, inland towns, and rural counties with very different access to testing, it pays to schedule your collection in advance.

Frequently asked questions

Do I need to fast?

Usually no. Fasting is not routinely required for fertility hormone tests unless your clinician asks for it.

When in my cycle should I test?

Some hormones are checked on specific cycle days, such as day 2 or 3, while others are checked later. Your clinician will tell you the right timing.

Does my partner need testing too?

Sometimes. Fertility involves both partners, so a clinician may recommend tests for one or both.

How long until results are ready?

Most results are available in about 1 to 3 business days, though this can vary by lab.
