BACKGROUND: The parallel and continued improvements in both infertility treatment and the management of malignancy cases have brought to the forefront the potential for fertility preservation. Using ovarian follicular resources can effectiv…

BACKGROUND: It is difficult to obtain healthy oocytes in poor ovarian responders with conventional treatment methods. Thus, the need to investigate new methods is essential. This study aims to investigate ovulation induction outcomes in pat…

BACKGROUND: The role of laparoscopy and hysteroscopy in managing unexplained infertility (UI) is debatable because of the improved success rate of assisted reproductive technologies (ART). This study aims to assess the findings of laparosco…

BACKGROUND: This study aimed to determine the alteration of endometrial expression levels of HOXA9/HOXA10/ HOXA11/HOXD10 genes and HOX transcript antisense intergenic RNA (HOTAIR) in mid-luteal phase endometrium in patients with hydrosalpin…

BACKGROUND: Endometriosis, is a prevalent condition among women of childbearing age, characterized by the presence of ectopic endometrial glands. It is associated with pelvic pain and infertility. Unfortunately, the diagnosis of endometrios…

Endometriosis is a common gynecological disease that occurs in between 6 and 10% of women who are at reproductive maturity. The presence of endometrial tissue outside the uterine cavity is the defining characteristic of this disease. Althou…

BACKGROUND: Endometriosis is an idiopathic gynecological condition affecting women with pelvic pain and infertility in reproductive ages. Due to preventive and therapeutic effects of soy isoflavones (SI) and broccoli extract (BE) on tumor a…

BACKGROUND: Embryo transfer (ET) is an important step in assisted reproductive technology. Uterine length measurement before ET (ULMbET) enables the determination of catheter length and anatomical variation before the ET. Therefore, in this…

BACKGROUND: The aim of this study was to evaluate the effects of thiamine (vitamin B1) on general health and infertility treatment outcomes in women with polycystic ovary syndrome (PCOS). MATERIALS AND METHODS: The study is a triple-blinde…

BACKGROUND: Repeated implantation failure (RIF) refers to the condition where high quality embryos are unable to successfully implant after multiple cycles of in vitro fertilization (IVF) treatment. The aim of this study is to investigate t…

BACKGROUND: Selecting embryos with the highest implantation potential is crucial for in vitro fertilization (IVF) success. Both the timing of blastulation, day 5 (D5) or D6, and the embryo quality have been suggested as influential factors …

BACKGROUND: The objective of this study was to investigate the correlation between the expression levels of sperm microRNA-149b and 34c and sperm quality in men diagnosed with oligoasthenoteratozoospermia. MATERIALS AND METHODS: In the exp…

Infertility is a serious health issue in the world affecting approximately 8-10% of couples worldwide. The meta-analysis study was performed to assess the prevalence and etiologic factors associated with infertility in Iran. We made sure th…

BACKGROUND: This study aims to determine whether pre or post-processing semen parameters obtained during intrauterine insemination (IUI) predict pregnancy when controlling for confounding effects. MATERIALS AND METHODS: A prospective cohor…

BACKGROUND: Past studies have shown that culturing slow-growing embryos from day 5 to day 6 may increase vitrification yield. This study aims to evaluate if the proportion of embryos eligible for vitrification increases by growing embryos n…

BACKGROUND: Endometriosis is identified as presence of the endometrium outside the uterine cavity. Retrograde menstruation contributes to the endometrial tissue implantation and the establishment of endometriotic lesions at ectopic sites. I…

BACKGROUND: The aim of this study was to investigate the effects of the antioxidant supplement of CoQ10 and placebo in the male infertility treatment. MATERIALS AND METHODS: The randomized controlled trial study was designed as a clinical …

BACKGROUND: Abnormal uterine bleeding (AUB) that is any irregularity in menstrual cycles causes women to refer to clinics. This study aimed to compare the efficacy, safety, and complications of endometrial ablation by the thermal balloon (C…

OBJECTIVE: Timing of frozen embryo transfer (FET) within a purported window of implantation is of increasing interest, and there is a paucity of evidence surrounding the transfer of frozen embryos early within these frozen embryo transfer p…

BACKGROUND: Hormones such as prolactin, by influencing expression of the endometrial genes, play a pivotal role in embryo implantation and development. The present study aimed to evaluate serum level of prolactin and its effect on altering …

Endometriosis is a chronic inflammatory disease defined by the presence of endometrial-like tissue outside the uterine cavity. Several authors have reported on the association between changes in inflammatory marker levels and the maintenanc…

BACKGROUND: Women who undergo in vitro fertilization (IVF) cycles should successfully go via multiple stages (i.e., clinical pregnancy, no abortion under 12 weeks, no abortion under 20 weeks, and delivery) to achieve a live birth. In this s…

BACKGROUND: In unicornuate uterus cases, when the rudimentary horn is very close to the uterus and is firmly attached, laparoscopic surgery can be very challenging due to the danger of massive bleeding and the possiblity of damaging the hea…

Embryo selection for in vitro fertilization (IVF) is an effort to increase the success rate of embryo implantation. Factors influencing the success of embryo implantation include embryo quality, endometrial receptivity, embryo characteristi…

Up to now, limited studies have been done to evaluate the effect of sexual activity during menstruation on the endometriosis. However, due to the menstrual-related symptoms of endometriosis, this study aimed to systematically review the pub…
