Text Extraction

Controlled ovarian stimulation is essential to obtain good pregnancy rates in assisted reproduction techniques. Options are natural cycle, minimal stimulation, traditional stimulation with gonadotrophins and GnRH analogs, with different regimes. There is a trend to practice a softer stimulation with less complications and more accessibility and comfort. However, we should not sacrifice efficiency, for that we have to select cases and design therapeutic modalities tailored to patient’s needs. We evaluate indications, advantages and disadvantages of each modality. Controversies are analyzed, including GnRH agonists versus antagonists, and recombinant versus urinary gonadotrophins. New commercial preparations are reviewed. Special emphasis is given to adjuvants like oral contraceptives, estrogens, insulin sensitizers, androgens, corticoids, acetyl salicylic acid, phosfodiesterase inhibitors, dopaminergic agonists and chorionic gonadotrophin.
