Potential of Plasma Rich in Growth Factors (PRGF-Endoret) to Enhance the Efficacy of Assisted Reproductive Techniques in Refractory Cases.

Aim: Nowadays, infertility problems affect a high percentage of couples. This study aimed to evaluate the effect of plasma rich in growth factors (PRGF-Endoret, hereafter PRGF) as a promising coadjuvant therapy in assisted reproductive techniques and its possible role in implantation and pregnancy rates. This retrospective study included 36 PRGF cycles in 27 women with one of the following reproductive disorders: recurrent implantation failure (n = 16), repeated abortion (n = 8), and thin endometrium (n = 3).

Ovarian response and pregnancy outcome in poor-responder women: a randomized controlled trial on the effect of luteinizing hormone supplementation on in vitro fertilization cycles.

Objective: To prospectively assess the effect of using a combination of recombinant follicle-stimulating hormone (rFSH) and recombinant luteinizing hormone (rLH) on ovarian stimulation parameters and treatment outcome among poor-responder patients.

Design: Prospective randomized trial.

Setting: University-associated private medical center.

Heterotopic pregnancy: two cases and a comparative review.

Objective: To analyze the incidence, diagnostic, and therapeutic management of heterotopic pregnancy by comparing a review for the 1971-1993 period with the one carried out in the present study (1994-2004).

Design: Review of the literature.

Setting: University teaching assisted reproductive technology (ART) center.
