ObjectiveTo compare the euploidy rate between ovulation suppression protocols using PPOS and GnRH-ant, and to evaluate possible variables associated with euploidy rate such as age, BMI, infertility duration, treatment-related factors, and s…

ObjectivePreimplantation genetic testing improves rates of assisted reproductive technologies success by selecting euploid embryos, reducing implantation failures and miscarriages. However, some factors in women may also impact outcomes, th…

ObjectiveTo evaluate the effects of COVID-19 vaccination (AstraZeneca® and CoronaVac®) on anti-Müllerian hormone (AMH) levels in threatened women.MethodsRetrospective cohort study evaluating serum AMH before and up to three vaccination dose…

Dynamic mutations in the 5' untranslated region of FMR1 are associated with infertility. Premutation alleles interfere with prenatal development and increase infertility risks. The number of CGG repeats that causes the highest decrease in o…

ObjectiveTo evaluate the impact of prior use of combined oral contraceptives in assisted reproduction techniques with ovulation blockade by oral progestin.MethodsRetrospective cohort study with a single-center convenience sample of patients…

ObjectiveSingle nucleotide variants have been implicated in the response to fertility treatment and a pharmacogenomic approach may help to customize therapy based on patient genome. We aimed to evaluate the effect, individual and combined, …

Infertility is a worldwide concern, affecting one in six couples throughout their reproductive period. Therefore, enhancing the clinical tools available to identify the causes of infertility may save time, money, and emotional distress for …

Background Single nucleotide variants (SNVs) FSHB :c.-211G>T, FSHR :c.919G>A, and FSHR :c.2039G>A were reported to be associated with the variability in FSH and LH levels, and in vitro fertilization (IVF) outcomes. In this study, w…

BACKGROUND: Endometriosis is a disease with an unknown pathogenesis that can lead to infertility. Endometrial polyps, fibroids, and polycystic ovarian syndrome (PCOS) have relatively high frequency and are causes of infertility. We hypothes…

Background: Endometriosis is a common gynecological disease associated with pelvic pain and infertility. There are discrepancies between the clinical presentation and the degree of the disease, suggesting the necessity of a better understan…

PURPOSE: to evaluate the frequency of VDR gene polymorphism Fok1 in infertile women with endometriosis and Control and its relation to the disease. METHODS: a case-control study that included 147 infertile women with endometriosis and 154 f…

OBJECTIVE: To describe the evolution of controlled ovarian hyperstimulation in women with recurrent ovarian endometriomas treated with sclerotherapy. METHODS: Twenty-one patients with a laparoscopic diagnosis of stage III or IV endometriosi…

PURPOSE: to evaluate the frequency and clinical picture of patients with incisional endometriosis. METHODS: retrospective descriptive study performed from the medical records of patients that underwent nodules resection in the surgical scar…

PURPOSE: to evaluate the ovarian reserve of infertile patients with severe ovarian endrometriosis, submitted to excisional surgery of endometriomas and attended from February to November, 2008. METHODS: prospective study, including 30 patie…

CONTEXT AND OBJECTIVE: Serological testing for CA125 has been widely used to detect endometriosis and to monitor its progression. However, controversy still exists regarding the usefulness of the plasma CA125 assay for diagnosing endometrio…
