Ultrasound has a primordial role in diagnosis and management of infertility; it is an essential tool in the office and in every fertility unit. It is important in the initial evaluation of the uterine and ovulatory factor, and complementary in the tubal and cervical factor. Transcervical instillation of saline solution allows better visualization of intracavitary defects (histerosonography). As such, histerosonography is a routine test in uterine cavity evaluation in assisted reproduction treatments (ART). Ovulation ultrasound monitoring of infertile women is needed for low and high complexity cycles. It also has an important role in ART high complexity cycles of during oocyte retrieval and embryo transfer. Its use for cyst aspiration is limited to exceptional cases and use of Doppler in fertility is still controversial and not practical.

First pregnancy and live birth occurs in assisted fertility clinic in Lima, Peru then obtained from the use of letrozole to stimulate ovulation in a patient 35, with secondary infertility of three years of development and two daughters of 8 and 7 year old. The patient was stimulated letrozole 2.5 mg / day, orally, from third to seventh day of the cycle, associated with hMG, 75 IU / day, IM, from the seventh day in use in October 0000 IU micronized progesterone as luteal support . The case demonstrates the usefulness of letrozole to induce ovulation as an alternative to other ovulation-inducing agent.

Induction of ovulation in patients with polycystic ovary syndrome. Current status of ovarian drilling. Occult ovarian failure: reproductive management. Ethical and legal aspects of assisted reproduction in Spain. Ovarian stimulation protocols and embryo quality. Low-complexity assisted fertilization.

The GnRH antagonists (GnRHant) protocol has allowed the use of GnRH agonist (GnRHa) as inductor of ovulatory discharge (OD) replacing human chorionic gonadotropin (hCG). An important advantage of GnRHa use in OD is that it significantly decreases the risk of ovarian hyperstimulation syndrome (OHSS) due to its luteolytic effect, important in cases of oocyte donors. Objectives: To compare proportion of oocytes obtained, oocyte/embryo  quality, reproductive result and OHSS incidence in consecutive oocyte donation cycles when OD was done with hCG or GnRHa. Cycles with preimplantation genetic diagnosis were compared. Design: Cohort retrospective study. Setting: Grupo PRANOR, Clinica Concebir, Lima, Peru. Participants: Oocyte donors and receptors. Interventions: A GnRHant protocol was used in 43 oocyte donors for 203 consecutive stimulation cycles and OD with hCG (n=127) or GnRHa (n=76) based...
