Aspiration of a single dominant follicle leads to improved cohort development and pregnancy in a patient with poor response to in vitro fertilization treatment.
OBJECTIVE
To report improved follicular cohort development and a healthy ongoing pregnancy after midcycle aspiration of a single dominant ovarian follicle in a patient with poor response to IVF treatment.


METHODS
Case report.


METHODS
University-based infertility center.


METHODS
A 39-year-old woman (gravida 1, para 0) with a borderline FSH level and four previous unsuccessful IVF attempts.


METHODS
A single 27-mm follicular cyst was aspirated after 13 days of treatment, while controlled ovarian hyperstimulation was continued.


METHODS
Number of follicles developed, number of oocytes retrieved, development of a clinical pregnancy.


RESULTS
In previous attempts, the patient had no more than two dominant follicles and a maximum of three oocytes retrieved. After midcycle aspiration of the single lead follicle, a new cohort of seven follicles developed and seven oocytes were recovered. Six embryos were replaced by tubal ET and an ongoing singleton gestation resulted.


CONCLUSIONS
Midcycle aspiration of a single lead follicle in a patient with poor response to IVF treatment allowed the development of a larger secondary cohort of follicles during the same cycle and ultimately led to a viable pregnancy. This intervention may have future implications for the treatment of poor responders.
