BACKGROUND: Recurrent implantation failure poses a significant challenge in assisted reproductive technology despite the transfer of high-quality embryos over multiple cycles. OBJECTIVE: This study aimed to compare the clinical outcomes be…

BACKGROUND: Women with low ovarian reserve are the capable part of people who refer to infertility centers, this study compares 2 treatment protocols in cases with low ovarian reserve. OBJECTIVE: This study aimed to compare the efficacy of…

PURPOSE: The selection of high-quality spermatozoa affects embryo quality and, consequently, the success rates of clinical outcomes. This study aimed to evaluate the efficacy of a cumulus cell-based sperm selection method for identifying hi…

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: Assisted reproductive technology (ART), offers hope for many infertile couples by increasing the chance of successful pregnancy. The success of in vitro fertilization depends on various factors, in which embryo transfer (ET) is …

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: Uterine blood supply has been identified as a potential factor in implantation failure. Objective: This study aimed to investigate Doppler indices in the uterine artery, including vascular flow and resistance, as well as the amo…

BACKGROUND: Recently, letrozole has been used to prevent moderate to severe ovarian hyperstimulation syndrome (OHSS) in assisted reproductive technology cycles due to its estrogen-reducing and androgen-increasing effects on the ovaries, aff…

BackgroundThe implantation rate after assisted reproductive technology depends on 2 important factors, good quality embryo and endometrial receptivity. Endometrial receptivity is mainly assessed by ultrasound measurement of endometrial thic…

BACKGROUND: Luteal phase deficiency is common in assisted reproductive technology and is characterized by inadequate progesterone production. Various studies have shown that administration of progesterone in fresh embryo transfer cycles inc…

BackgroundThe miscarriage rate after pregnancy resulting from assisted reproductive technology (ART) is about 20%, roughly half of which is biochemical. The correlations between the number and quality of oocytes, estradiol level and early p…

Homocysteine is one of the components of follicular fluid (FF), so that any disruptions in its concentration may affect oocyte development. The aim of this study was to determine the relationship between FF homocysteine concentration and em…

BACKGROUND: In vitro fertilization is an important therapy for women with polycystic ovarian syndrome (PCOS). The use of new ways of improving clinical results is yet required. OBJECTIVE: This study was aimed to investigate the efficacy of…

BACKGROUND: Despite major advances in assisted reproductive techniques, the implantation rates remain relatively low. Some studies have demonstrated that intrauterine infusion of granulocyte colony stimulating factor (G-CSF) improves implan…

BACKGROUND: Although pregnancy rate in in vitro fertilization-embryo transfer (IVF-ET) cycles has been increased over the preceding years, but the majority of IVF-ET cycles still fail. Granulocyte colony stimulating factor (GCSF) is a glyco…

BACKGROUND: Gonadotropin-releasing hormone (GnRH) plays essential roles in embryo implantation, invasion of trophoblastic tissue, and steroid synthesis in the placenta. OBJECTIVE: The aim of this study was to evaluate the effect of GnRH an…

BACKGROUND: Genital tuberculosis (GTB) is an important cause of female infertility, especially in developing countries. The positive results of polymerase chain reaction (PCR) in endometrial GTB in the absence of tubal damage raise the poss…

BACKGROUND: Primary and secondary infertility are the most common presenting symptom in patients with pelvic tuberculosis (PT). Endometriosis is commonly associated with an increased risk of infertility. CASE: Here, we report a rare case o…

BACKGROUND: Poor ovarian response to controlled ovarian stimulation is one of the most important interest points in assisted reproduction. Mild ovarian stimulation seems to be preferable to high dose of FSH regimens in women with a history …

BACKGROUND: Frozen- thawed embryo transfer is an essential part of ART treatment and outcomes of this procedure are associated with several clinical factors. Several studies have showed an increase level of IVF outcomes in women with suffic…

BackgroundFrozen embryo transfer (FET) is one of the most important supplementary procedures in the treatment of infertile couples. While general information concerning the outcome of fresh embryo transfer has been documented, paucity of in…

Malignancies are not rare in girl and women during their reproductive years. Over the past three decades, the survival rate for cancer has been improving due to progress in cancer diagnosis and treatment. These patients frequently experienc…

BACKGROUND: We often see patients with a thin endometrium in ART cycles, in spite of standard and adjuvant treatments. Improving endometrial growth in patients with a thin endometrium is very difficult. Without adequate endometrial thicknes…

BACKGROUND: Gonadotrophin-releasing hormone (GnRH) agonist is used for controlling ovarian stimulation in assisted reproductive technology (ART) cycles which has some benefits. OBJECTIVE: To compare the efficacy of two different formulatio…
