Filariasis infection is a probable cause of implantation failure in in vitro fertilization cycles.
OBJECTIVE
To describe a parasitic infection that probably affected the implantation of good-quality embryos in an in vitro fertilization (IVF) cycle.


METHODS
Case report.


METHODS
Tertiary care center in a university hospital.


METHODS
A 36-year-old Caucasian female with primary unexplained infertility. The patient underwent two cycles of IVF with good-quality embryos transferred; however, no pregnancy ensued despite adequate luteal support.


METHODS
In vitro fertilization cycles, CBC, blood smear, evaluation for eosinophilia including serological evaluation for parasitic infections.


METHODS
Pregnancy.


RESULTS
Following treatment for filariasis, a repeat IVF cycle using the same stimulation protocol yielded a full-term pregnancy.


CONCLUSIONS
This case is of particular importance because, to our knowledge, it is the first to describe a parasitic infection that probably affected the implantation of good-quality embryos in IVF cycles.
