BACKGROUND: This study aims to determine the effect of laparoscopic surgery for advanced endometriosis on spontaneous pregnancy rates and assisted reproductive techniques (ARTs) in patients with endometriosis. MATERIALS AND METHODS: This r…

BACKGROUND: Myomectomy is commonly performed on women diagnosed with symptomatic uterine leiomyoma(s). This study aimed to evaluate the effects of myomectomy on the serum anti-Müllerian hormone (AMH) levels in women with uterine myoma. MAT…

BACKGROUND: This research delves into exploring the nexus between lipid profiles and pro-inflammatory cytokines in both blood and follicular fluid (FF). It examines their impact on assisted reproductive technology (ART) outcomes and the pro…

BACKGROUND: Limited data exist regarding the outcomes of frozen-thawed cleavage-stage embryos that undergo extended culture to reach the blastocyst stage. This study aimed to compare the pregnancy outcomes between two approaches: transferri…

BACKGROUND: There is a lack of reliable data or evidence-based protocol for the management of deep infiltrating endometriosis (DIE) lesions in reproductive age women. This study examines ovarian reserves in women who underwent endometriosis…

BACKGROUND: Reproductive dysfunctions of polycystic ovary syndrome (PCOS) and blood anti-mullerian hormone (AMH) concentration are significantly influenced by the dietary advanced glycation end products (AGEs). The interplay between AGEs an…

BACKGROUND: The study was conducted to investigate the effect of dual trigger with gonadotropin-releasing hormone agonist (GnRH-a) and standard dose human chorionic gonadotropin (hCG) on in vitro fertilization/intracytoplasmic sperm injecti…

BACKGROUND: The effectiveness of changing the type of luteal phase support in patients with poor ovarian response (POR) remains unclear based on the available evidence. This study aimed to compare the effectiveness of various luteal phase s…

BACKGROUND: Cynodon dactylon traditionally employed or treating hormonal problems in women. Therefore, this study aimed to assess the effect of C. dactylon hydroalcoholic extract of on letrozole-induced polycystic ovary syndrome (PCOS) in a…

Endometriosis is a chronic gynecological condition defined by the ectopic presence of endometrial-like tissue outside the uterine cavity, often resulting in debilitating symptoms and significant impacts on quality of life. While the exact e…

BACKGROUND: The World Endometriosis Research Foundation (WERF) Endometriosis Phenome and Biobanking Harmonisation Project (EPHect) aims to facilitate international research on endometriosis by developing a standardized questionnaire. This s…

BACKGROUND: The follicular fluid (FF) of mature oocytes contains a high concentration of growth factors and cytokines that have the potential to influence implantation in either a paracrine or autocrine manner. During the physiological proc…

BACKGROUND: Myometrial thickness has been expected to be a prognosticator for lower uterine segment function. An abnormal function of the uterine muscle layer can cause common and important reproductive problems. This study aimed to evaluat…

BACKGROUND: Ovarian reserve is one of the most important factors that influences the success of assisted reproductive technology (ART). Recently, the role of anti-müllerian hormone (AMH) in ART has been investigated as a marker for the pred…

BACKGROUND: This research was aimed at assessing the relationship between the follicular fluid (FF) antioxidants activity, aging and in vitro fertilization (IVF) outcome. MATERIALS AND METHODS: The present cross-sectional study was carried…

BACKGROUND: There is an ongoing debate about the optimal dosage of gonadotropin-releasing hormone (GnRH) agonist for oocyte triggering in polycystic ovarian syndrome (PCOS) patients at risk for ovarian hyperstimulation syndrome (OHSS). In t…

BACKGROUND: This study aims to investigate the effects of carob (Ceratonia siliqua L.) pod extract (CPE) on the viability of human endometrial mesenchymal stromal/stem cells (EnMSCs) and its impact on mRNA and protein expressions of DNA met…

BACKGROUND: Various protocols have been approved to improve the response rate leading to successful fertilization in poor ovarian responders (PORs). The application of double ovarian stimulation (DuoStim) in the follicular and luteal phases…

BACKGROUND: Frozen embryo transfer (FET) has been increasingly used due to advancements in cryopreservation techniques and the safety advantages. This study aims to determine various factors influencing the successful FET. MATERIALS AND ME…

BACKGROUND: While the effects of polycystic ovary syndrome (PCOS) and infertility on women's health have often been discussed, not many studies have assessed the other complications of infertility. One of these complications is female sexua…

BACKGROUND: Platelet-rich plasma (PRP) therapy has been shown to enhance tissue regeneration by expressing several cytokines and growth factors (GFs). This study investigated the effect of intrauterine infusion of PRP as a noninvasive autol…

BACKGROUND: Severe oligoasthenoteratozoospermia (OAT), characterized by a reduced sperm count, motility, and altered morphology, presents a significant challenge in the field of male infertility. Platelet-rich plasma (PRP), renowned for its…

BACKGROUND: Oxidative/nitrosative stress in the oocyte microenvironment could have an impact on intracytoplasmic sperm injection (ICSI) outcomes. The presence of reactive oxygen species (ROS) and reactive nitrogen species (RNS) can stimulat…

BACKGROUND: Vaccination against Coronavirus-19 disease (COVID-19) was widely administered from 2021 onwards. There is little information on how this vaccine affected fertility after assisted-reproductive-technology (ART). The aim of this st…

BACKGROUND: Endometrial scratching (ES) remains controversial regarding its potential effectiveness in improving pregnancy rates. The objective of the present study was to assess the impact of endometrial fundal incision (EFI) during hyster…
