“Poor responder” is a term that may be used to describe a person whose ovaries and body do not respond to fertility medications. They typically require higher doses of stimulation medications to produce 4 or less than the optimal number of eggs needed for IVF treatment. This usually means that they will have a lower chance of pregnancy in that IVF cycle.
A poor responder diagnosis is usually discovered after an IVF cycle that results in a poor stimulation outcome. Ovarian reserve testing can be performed to identify potential issues ahead of time, with a fertility specialist checking the FSH levels and conducting a clomiphene challenge test. The clomiphene challenge test is usually conducted if a woman’s FSH level is 10-15 mIU/mL or the estradiol level is greater than 65 pg/mL. An ultrasound assessment can also help predict resting and antral follicle numbers. Cycle day 3 blood testing of the Inhibin B levels can help determine poor responders as well.
There are many reasons that a woman could be a poor responder to infertility treatment. Possibilities may include obesity, the wrong type of ovarian stimulation, poor injection techniques, and too little ovarian stimulation. Being a poor responder often comes as a result of diminished ovarian reserve (DOR), or low functional ovarian reserve.
Women who are diagnosed as poor responders should discuss whether they fall in the spectrum with their fertility specialist. A few different treatments for poor response to ovarian stimulation may include:
- Modifying stimulation cycle medications, such as different types and amounts of gonadotropins
- Altering the pituitary down regulation protocols
- Advanced laboratory techniques, such as assisted hatching, continuing egg retrieval despite low follicle numbers, or day 2 transfers
- Adjuvant therapy, such as growth hormone or androgen pretreatment
