Endometrium is one of the main factors in pregnancy. During assisted reproductive technology (ART) treatments, some cycles are cancelled due to inadequate endometrial growth. This study was conducted to evaluate the effectiveness of platelet-rich plasma (PRP) in the treatment of thin endometrium. Ten patients with history of inadequate endometrial growth in frozen-thawed embryo transfer (FET) cycles were recruited into the study. Intrauterine infusion of PRP was performed. Endometrial thickness was assessed...

The freeze-all strategy has emerged as an alternative to fresh embryo transfer (ET) during in vitro fertilization (IVF) cycles. Although fresh ET is the norm during assisted reproductive therapies (ART), there are many concerns about the possible adverse effects of controlled ovarian stimulation (COS) over the endometrium. The supra-physiologic hormonal levels that occur during a conventional COS are associated with modifications in the peri-implantation endometrium, which may be related to a decrease in pregnancy rates and poorer obstetric and perinatal outcomes when comparing fresh to frozen-thawed embryo transfers...

Post-treatment fertility emerges as an important issue in the early counseling of individuals with cancer, since survivors may have their quality of life affected by the occurrence of functional failure of the gonads because of antineoplastic therapies. In the context, oncofertility has been developed as an interdisciplinary field of study that combines expertise in reproductive medicine and oncology, to provide strategies aiming to maintain the possibility of future procreation. Today, we have many options and techniques available for the preservation of gametes in men and women...

Several discoveries have been described recently (5-10 years) about the biology of ovarian follicles (oocyte, cumulus cells and granulosa cells), including new aspects of cellular communication, the control of oocyte maturation and the acquisition of oocyte competence for fertilization and further embryo development. These advances are nourishing assisted reproduction techniques (ART) with new possibilities, in which novel culture systems are being developed and tested to improve embryo yield and quality. This mini-review aims to describe how the recent knowledge on the physiological aspects of mammalian oocyte is reflecting as original or revisited approaches into the context of embryo production...

OBJECTIVE: ART has helped millions of infertile couples worldwide to overcome their childlessness. These successes have been accompanied by an increase in multiple deliveries, and perinatal complications associated. The explanation for this complication is the transfer of more than one embryo, to increase the odds of delivery. Our objective was to compare the outcome of elective dual embryo transfer (eDET) to that of the transfer of more than two embryos without embryo cryopreservation (TET), terms of delivery rate and multiple delivery...

OBJECTIVE: In controlled ovarian hyperstimulation (COH) using antagonist cycles, an incomplete luteolysis could happen after an inefficient previous luteolysis. Since antagonist cycles are frequent today, this study aims to access the impact of serum progesterone in the beginning and at the end of stimulation, and pregnancy outcomes. METHODS: single-center cohort study, 461 fresh embryo transfers in ICSI antagonist cycles. Serum progesterone levels was measured in the beginning of COH (P4i) and on hCG day (P4f) using threshold values of 1...

Recurrent miscarriage places a huge psychological burden on a woman who is trying to conceive. Meanwhile, the use of traditional medicine still plays an important role within the Saudi Arabian culture, where many patients still seek alternative forms of therapy. However, this traditional way of treatment might expose patients to many hazards. We present a case of a 32-year-old pregnant woman with a history of infertility and recurrent miscarriages. She used large amounts of myrrh herbs for 2 months, since a traditional healer told her that her current pregnancy would progress safely by its use...

Pre-implantation genetic diagnosis (PGD) or screening (PGS) technology, has emerged and developed in the past few years, benefiting couples as it allows the selection and transfer of healthy embryos during IVF treatments. These techniques can be performed in oocytes (polar-body biopsy) or embryos (blastomere or trophectoderm biopsy). In this case report, we describe the first two live births to be published in Brazil after a polar-body (PB) biopsy. In case 1, a 42-year-old was submitted to PB biopsy with PGS due to advanced maternal age and poor ovarian reserve...

Final oocyte maturation with Human Chorionic Gonadotropin (hCG) and ovarian stimulation with Follicle Stimulation Hormone (FSH) combined with Gonadotrophin-releasing Hormone (GnRH) antagonist to block Luteinizing hormone (LH) surge is a standard procedure of in vitro Fertilization (IVF) and Intracytoplasmic Sperm Injection (ICSI). However, GnRH agonist has been replacing the use of hCG in certain situations, especially in patients at risk of Ovarian Hyperstimulation Syndrome (OHSS). Some studies have also shown advantages in the combined use of GnRH agonist concurrently with hCG in inducing final oocyte maturation, a treatment known as "Dual Trigger"...

This global overweight and obesity epidemics has become one of the largest public health problem worldwide and is increasingly more common among women in reproductive age. Along with the prevalence of overweight women, there is an increase in women with anovulatory infertility. Thus, we carried out a bibliographic research in the PubMed, Lilacs and SciELO databases, using the combinations in Portuguese, Spanish and English of the following descriptors: "Body Mass Index", "obesity", "overweight", "female infertility" and "anovulation"...
