In vitro fertilization (IVF) is a procedure used to help individuals and couples achieve pregnancy, and it requires medical supervision. The process involves stimulating the ovaries, retrieving eggs, fertilizing those eggs in a lab, and transferring an embryo into the uterus. Before treatment begins, patients usually complete several tests that assess different aspects of reproductive health. Here are some of the tests involved in IVF:
Ovarian Reserve Testing
Ovarian reserve testing looks at the number and likely quality of a woman’s remaining eggs. This part of the IVF workup, which guides expectations for how the ovaries will respond to fertility medications, provides key clinical insight. It does not measure pregnancy outcome on its own, but it offers information about ovarian function. Several hormones are measured to evaluate ovarian reserve, including:
- Anti-Müllerian Hormone: The AMH blood test reflects the pool of developing follicles in the ovaries and is an indicator of fertility.
- Follicle-stimulating hormone: FSH is measured early in the menstrual cycle to evaluate how hard the body is working to stimulate egg development.
- Estradiol: This hormone is usually measured alongside FSH early in the menstrual cycle. Elevated estradiol levels sometimes mask a higher FSH level, affecting the assessment of ovarian reserve.
- Luteinizing hormone: Typically measured to evaluate ovulation, abnormal LH levels can indicate issues such as polycystic ovary syndrome (PCOS) or other ovulatory disorders.
These results are used to estimate how many eggs will develop during stimulation. They also help determine whether a patient may need a different medication regimen, dose, or treatment timeline during IVF. Because hormone levels fluctuate throughout the menstrual cycle, clinicians interpret these results alongside ultrasound findings to improve the accuracy of ovarian reserve assessment.
Infectious Disease Screening
Infectious disease screening is a routine part of preparing for in vitro fertilization, and it helps confirm patient safety before treatment begins. These tests look for infections that may affect the patient, reproductive tissues, lab procedures, or embryo development. The screening’s goal is to identify risks early so treatment decisions can be made with full information. Common screening panels include tests for HIV, hepatitis B and C, and syphilis, but some clinics also order testing based on medical or travel history. Depending on the treatment plan and clinic protocols, both partners can be tested to complete the evaluation.
Uterine Evaluations
The uterus must be examined before embryo transfer. A uterine evaluation checks the shape and condition of the uterine cavity, helping detect problems that may interfere with implantation. If an abnormality is present, the treatment team often adjusts the plan or recommends further care before transfer. Some common tests include:
- Hysterosalpingography: HSG is an imaging study that uses a dye and X-ray technology to visualize the uterus and fallopian tubes.
- Saline sonohysterography: This uses sterile saline and ultrasound to produce a clearer view of the uterine cavity.
- Hysteroscopy: A thin camera is placed through the cervix to inspect the inside of the uterus directly.
Semen Analysis
Male fertility is a key part of the IVF evaluation, and semen analysis measures several features of a sperm sample. This helps identify patterns that are linked to male reproductive health. The sample is collected in a clinic and then examined in a lab.
The report typically includes sperm count, and it is used as a standard marker in fertility assessment. It also measures motility, or how well sperm move, and morphology, or the size and shape of the sperm. Semen volume is also reviewed, as low volume can indicate issues with sample production or delivery.

IVF testing gives doctors an overall view of reproductive health before treatment starts. Ovarian reserve testing, infectious disease screening, uterine evaluations, and semen analysis provide distinct information that informs the care plan. Together, these assessments help create a more personalized approach to IVF. If you want more information about testing or treatment steps, speak with a fertility specialist today.
