OBJECTIVE: To explore whether post-embryo transfer (ET) air travel affects in vitro fertilization (IVF) outcomes, addressing the growing concern in medical tourism where patients frequently travel for fertility treatments. METHODS: This re…

OBJECTIVE: To evaluate Dydrogesterone's effectiveness in PPOS protocols for IVF/ICSI or oocyte cryopreservation, focusing on LH surge suppression and metaphase II oocyte yield. METHODS: A retrospective, comparative, single-center study of …

OBJECTIVE: To investigate the effects of dietary quercetin on the retrieved mouse oocytes and IVF outcomes. METHODS: Female mice were divided into two groups. Mice were given 0.2 mL water without (control group) or with quercetin 30 mg/kg …

OBJECTIVE: To compare recombinant FSH (rFSH) with highly purified-human menopausal gonadotrophin (hp-hMG) on ovarian response in women undergoing elective fertility preservation (FP). METHODS: This retrospective study included 456 women wh…

OBJECTIVE: To examine the relationship between oxidative stress markers and reproductive parameters in women undergoing assisted reproductive treatments, focusing on the interaction between demographic, oxidative, and reproductive factors. …

OBJECTIVE: The aim of this study is to evaluate the intensity of five antibodies against extractable nuclear antigens (ENA: RNP, ScL-70, SS-B, SS-A, and Sm) in infertile patients with endometriosis. METHODS: We investigated infertile women…

OBJECTIVE: Preimplantation 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, …

OBJECTIVE: It has been observed that faster developmental kinetics are linked with a higher number of embryo cells, improved blastocyst development, and increased rates of implantation and pregnancy. However, the embryonic morphokinetics' p…

OBJECTIVE: To evaluate whether ovulation triggers improve pregnancy and/or ovulation rates in women with unexplained or anovulatory infertility undergoing ovulation induction and natural intercourse or intrauterine insemination (IUI), witho…

OBJECTIVE: To investigate perception of (in)fertility, fertility-related quality of life, and depression in women undergoing assisted reproductive treatment. METHODS: Cross-sectional study, quantitative approach. The research sample compri…

This review examines the impact of Assisted Reproductive Technology (ART) on prospective parents and born children, as well as their parental relationships, considering their emotional and social context. Specific situations are analyzed, s…

OBJECTIVE: Polycystic ovary syndrome (PCOS) is the most prevalent endocrinopathy and is often associated with elevated levels of anti-Müllerian hormone (AMH) and obesity. AMH may influence the reproductive prognosis of women undergoing in v…

OBJECTIVE: To assess the prevalence of self-reported symptoms of endometriosis and adenomyosis among university students and identify potential predictors of these diseases among these symptoms. METHODS: This cross-sectional study was cond…

OBJECTIVE: To evaluate the effects of COVID-19 vaccination (AstraZeneca® and CoronaVac®) on anti-Müllerian hormone (AMH) levels in threatened women. METHODS: Retrospective cohort study evaluating serum AMH before and up to three vaccinatio…

OBJECTIVE: Emotional stress leading to cortisol release is an important infertility factor in females. Increased cortisol levels can significantly affect tight junction proteins and dysregulate the implantation process. This study investiga…

Endometriosis is a chronic disease that affects around 10% of reproductive age women worldwide and a common cause of infertility. One of its manifestations is ovarian endometriomas, which are present in 17-44% of endometriosis patients. End…

In this case report, we review a patient in whom ovarian reserve parameters increased significantly following treatment of uncontrolled diabetes. The patient is a previously healthy, lean 29-year-old woman in a same-sex relationship who was…

This systematic review and meta-analysis aimed to evaluate the benefit of GnRH agonist (GnRHa) in reproductive outcomes among women with adenomyosis undergoing IVF. The utility of GnRHa protocols for controlled ovarian stimulation (COS) and…

OBJECTIVE: To evaluate the correlation between serum anti-Müllerian hormone (AMH) and the number of oocytes retrieved after controlled ovarian stimulation for in vitro fertilization treatments and determine cut-off values predictive of poor…

Antimüllerian hormone (AMH) is a homodimeric glycoprotein secreted by granulosa cells from primary to large antral follicles, and it plays an important role in the regulation of early follicle growth. It is considered a reliable marker of o…

OBJECTIVE: The primary goal of this article is to analyze whether there is still room for ovarian stimulation in poor responders prescribed the long protocol. METHODS: This retrospective cohort study analyzed the medical charts of patients…

ObjectiveTo analyze if partial premature ovulation (PPO) detection during oocyte pick-up (OPU) impairs the quality of the retrieved oocyte cohort.MethodsThe PPO concept refers to the situation when premature ovulation happens only in some o…
