Background & Aims: Concentrations of certain substances in follicular fluid (FF) may
related to fertilization outcome. The study aim was to identify FF markers with
which to predict embryo implantation potential. 
Materials & Methods: Concentrations of selected hormones, cytokines and growth factors in
FF samples obtained during assisted reproduction treatment, Intracytoplasmic
Sperm Injection (ICSI) method were related with treatment outcomes. 
Results: Mean
concentrations of 17beta-estradiol (E2), prolactin (PRL) and insulin-like
growth factor (IGF)-I were significantly higher, in treatment attempts leading
to a clinical pregnancy as compared with those in which no pregnancy was
established. LH, growth hormone (GH), progesterone, and interleukin-1 (IL-1)
concentrations are similar in successful and unsuccessful attempts.
Conclusions: Fertilization
outcomes were related to FF levels of PRL, E2 and IGF-I. But LH, growth GH,
progesterone, and IL-1 are not markers of success.
