Scar endometriosis is an uncommon condition in which endometrial tissue grows in a previous surgery wound site. The triad of scar endometriosis includes the history of caesarean section or any other gynecological surgery, cyclical waxing, a…

OBJECTIVE: The present study aims to assess the success of controlled ovarian stimulation in intrauterine insemination cycles stimulated by recombinant-FSH and Clomiphene citrate for either mono- or bi-follicular development. METHODS: We a…

OBJECTIVE: The recent improvement in sequential media has refocused its attention on the role of human blastocysts in ART, not only because of its advantages but also because of the possible cancellation of embryo transfer when relying on b…

OBJECTIVE: Luteal phase defect in patients undergoing assisted reproductive technology (ART) is a sign of uterine failure due to insufficient progesterone effects on the endometrium. This study aims to compare the success rate and side effe…

OBJECTIVE: Reproductive medicine needs to find some ways to predict pregnancy outcomes and implantation, which are non-invasive and accurate. Immunologic factors and interleukins are good choices reported in the literature. The purpose of t…

OBJECTIVE: The use of gonadotropin-releasing hormone agonist (GnRHa) as an alternative for human chronic gonadotropin (hCG) trigger has potential benefits, but the optimal luteal phase support (LPS) following GnRHa trigger remains to be elu…

OBJECTIVE: We compared the efficacy, safety, and immunogenicity of a biosimilar recombinant human follicle-stimulating hormone (Folitime®) with Gonal-f® in women undergoing ovarian stimulation for in-vitro fertilization. METHODS: This rando…

This integrative review evaluated the most commonly diagnosed causes of infertility in men and women in Brazil, as well as the medically assisted reproduction technologies regularly employed in these cases. We searched in four electronic da…

Spontaneous hemothorax is a rare disorder characterized by pleural fluid hematocrit greater than 50% of the peripheral blood hematocrit without natural or iatrogenic trauma to the lungs or pleural space. Since the first case of COVID-19, mo…

OBJECTIVE: To investigate if high anti-Müllerian hormone (AMH) concentration is a useful tool to predict the outcome of assisted reproductive treatment. METHODS: Retrospective cohort study involving 520 patients who underwent IVF/ICSI proc…

OBJECTIVE: Some studies have shown that it is possible to evaluate tubal permeability through MRI. Our aim is to perform a prospective study and to perform a comprehensive review in the literature regarding HSG-MRI. METHODS: We carried out…

Multiple sclerosis (MS) is a neurological disease that typically affects young women of reproductive age. There are still many questions and heterogeneous clinical approaches partly due to the lack of consensus and guidelines. For many year…

OBJECTIVE: To study donor and recipient factors affecting cumulative live birth rate (CLBR) in oocyte donor IVF (OD- IVF) cycles. METHODS: The present retrospective study was conducted at the ART center of a tertiary care referral hospital…

Oocyte quality could be negatively affected by many factors including smoking, alcohol consumption, obesity, woman's age, endometriosis and controlled ovarian stimulation (COS), during assisted reproductive technology (ART), in addition to …

OBJECTIVE: Endometriosis is associated with infertility, even without an anatomical abnormality. Furthermore, the peritoneal (mild) phenotype of this disease is the most prevalent and linked to infertility. The present study aimed to invest…

OBJECTIVE: The aim of the present study is to investigate embryo quality (score) after controlled ovarian stimulation for IVF using rFSH or hMG with the GnRH antagonist protocol. METHODS: Open, randomized, single center study. The patients…

OBJECTIVE: This study aimed to assess the effect of endometrioma surgery on ovarian reserve by measuring anti-Müllerian hormone (AMH) levels. METHODS: This systematic review and meta-analysis included observational studies and randomized c…

ObjectiveFollicular Output Rate (FORT) is an efficient quantitative and qualitative marker of ovarian responsiveness to gonadotropins. Transdermal testosterone (TT) has been used as adjuvant therapy to gonadotrophins in order to improve ova…

Congenital abnormalities of the uterus result primarily from embryological maldevelopment of the paramesonephric ducts and have been associated with pregnancy complications, reduced fertility, and other adverse fetal outcomes. While such ab…

OBJECTIVE: To investigate the predictive role of inflammatory hematological markers on treatment success in in vitro fertilization (IVF) patients. METHODS: In this study, we analyzed the data from the patients who admitted to our IVF cente…

OBJECTIVE: The aim of this study was to evaluate the fertilization and blastocyst formation rates of oocytes in metaphase I (MI) obtained from women who underwent controlled ovarian hyperstimulation (COH) for intracytoplasmic injection. ME…

INTRODUCTION: Despite recent advances in assisted reproduction techniques and recent knowledge regarding embryo and endometrium quality, implantation and birth rates remain low. The objective of this study was to investigate whether clomiph…

Primary ovarian insufficiency is a cause of infertility that affects about 1% of women under 40 years old, and is considered as idiopathic in 75% of cases. This review aims to carry out a critical synthesis of the knowledge of the chemical …

OBJECTIVE: To define the factors associated with clinical pregnancy after intrauterine insemination. METHODS: Retrospective study involving 633 infertility couples, which made up to 1053 cycles of intrauterine insemination. We analyzed the…
