OBJECTIVE: Endometrioma surgery is associated with a reduction in ovarian reserve. However, removal of an endometrioma may increase the likelihood of a spontaneous conception. The objective of this study was to assess the pre-operative and …

Assisted Reproductive technology encompasses all techniques involving ovarian stimulation to produce high-quality oocytes and manipulation of both oocytes and sperm in vitro to produce embryos for the purpose of reproduction. The final matu…

The vaginal microbiome is dominated by Lactobacillus spp. and the depletion of these microorganisms have been associated with adverse conditions that can affect women's health. Disturbance of the vaginal niche with a non-lactobacillary micr…

OBJECTIVE: Advances in embryo culture conditions and the development of vitrification as a revolutionary cryopreservation method have allowed for routine use of blastocyst transfer in assisted reproduction technology (ART) cycles. Several v…

Carbon nanostructures are important nanomaterial with interesting physical and chemical properties. These nanostructures have been assessed for application in different fields of medicine, such as cancer detection and treatment, Parkinson d…

OBJECTIVE: To evaluate the association among embryonic morphological parameters, clinical factors and euploid blastocyst formation. METHODS: This prospective cohort study included 422 blastocysts from 135 patients who had undergone preimpl…

OBJECTIVE: To evaluate whether platelet-rich plasma (PRP) optimizes endometrial thickness (EMT) and improves live birth rates (LBR) in women with refractory thin endometrium due to varied aetiology during fresh in vitro fertilization (IVF) …

OBJECTIVE: Endogenous prostaglandins are involved in hemostasis, renal excretion of electrolytes, and implicated in dysmenorrhea. Piroxicam and Nitroglycerin are common drugs used in treating dysmenorrhea by inhibiting the cyclooxygenase pa…

OBJECTIVE: To compare the number of oocytes obtained in the follicular puncture of high- responder oocyte donors, submitted to ovarian stimulation for in vitro fertilization (IVF) in two different protocols: Friendly and Conventional. METH…

ObjectiveIs the AMH level correlated with age and number of mature oocytes retrieved from stimulated cycles?MethodsThis descriptive, retrospective, observational study included the data of about 1500 patients submitted to Assisted Reproduct…

OBJECTIVE: This study aimed to determine whether or not developmental potential impacts clinical outcomes, when good grade blastocysts from Days 5 and 6 were transferred in frozen embryo transfer (FET) cycles. METHODS: 654 women, including…

Dealing with unexplained infertility is still non-guided, and patients are prone to different and sometimes discordant management strategies based on physician's preferences. However, much has been discussed in this matter, especially when …

An objective and individualized approach of in vitro fertilization techniques tends to decrease costs and improve the experience of infertile couples during treatment. The use of available technologies to diagnose and treat infertility base…

OBJECTIVE: Repeated implantation failure (RIF) is a major challenge in reproductive medicine. On the other hand, there has not yet been established a confirmed outcome regarding the usage of platelet-rich plasma (PRP) in women undergoing in…

ObjectiveTo determine whether elective frozen embryo transfer (eFET), or the 'freeze-all' strategy, associated with better cumulative clinical outcomes compared with fresh embryo transfer (ET).MethodsA total of 7,236 IVF cycles that were fo…

OBJECTIVE: A prolonged culture of embryos beyond day 2-3 to day 5 (blastocyst culture) after fertilization might be an alternative, simple way of selecting suitable embryos for transfer. Extending embryo culture to day 5/6 is a selection to…

OBJECTIVE: The first aim of this study was to investigate the effect of apixaban on endometrial receptivity via immunohistochemical investigation of integrin β3 expression in pregnant rats. The second aim was to compare the endometrial effe…

It is well known that female reproduction ability decreases during the forth decade of life due to age-related changes in oocyte quality and quantity; although the number of women trying to conceive has today increased remarkably between th…

OBJECTIVE: To investigate the effect of endometriosis and its different stages over Intracytoplasmic Sperm Injection (ICSI) outcomes among infertile women without previous history of ovarian surgery. METHODS: A total of 440 women enrolled …

OBJECTIVE: Although there has been increased utilization of assisted reproductive technologies (ART) in the world, there is no conclusive definition about the relationship between the success rate of ART and national wealth. METHODS: In th…

Conventional embryo assessment is performed by removing embryos from incubators at least once a day. However, it is static and limited to specific time points, reducing the amount of information that could potentially be obtained. Fortunate…

OBJECTIVE: Ectopic pregnancy is a well-known complication following in vitro fertilization with embryo transfer; studies have questioned, however, whether there are risk factors that could be identified before the procedure. The objective o…

Adenomyosis is a gynecological condition, which is characterized by stromal and glandular endometrial tissue infiltration inti the myometrium, resulting in an increase of uterine volume. The etiology of adenomyosis is presently unknown, but…
