BACKGROUND: Endometriosis is defined as the existence of endometrial glands and stroma outside the uterine cavity. This disease is responsible for about 15% of the indications for assisted reproductive technologies (ART). MATERIALS AND MET…

Background: In vitro fertilization has advanced in many ways, and new techniques are challenging. Blastocyst transfer is an alternative method for embryo transfer (ET) to improve in vitro fertilization outcomes. Objective: The present study…

BACKGROUND: Endometriosis is a disease that affects women of reproductive age. This disease is characterized by the presence of endometrial-like tissues (endometrial or stromal glands) outside the uterus and shows significantly elevated pre…

BACKGROUND: Infertility is a serious health problem that affects the individual, her/his family, and the community. Infertility is defined as failure to achieve clinical pregnancy after at least 12 months of unprotected coitus. OBJECTIVE: …

BACKGROUND: Ovarian hyperstimulation syndrome (OHSS) is one of the most important complications of assisted reproduction treatment. Many substances are involved in the regulation of the vascular permeability, which have been concerned to ca…

BACKGROUND: Implantation is one of the essential steps for the success of assisted reproductive techniques (ART). Their success depends on three main factors: embryo quality, endometrial receptivity (ER), and synchrony between embryo and en…

BACKGROUND: Based on classical two-cell, two-gonadotropin theory, in the follicle, follicle-stimulating hormone (FSH) and luteinizing hormone (LH) put on their main effects on the granulosa and theca cells. LH is essential for androgens pro…

BACKGROUND: Endometrial receptivity is required for successful implantation and pregnancy. Despite the remaining controversy, many studies have shown that ultrasonographic endometrial thickness can be considered as an indicator of endometri…

BACKGROUND: Endometriosis is one of the most common gynecologic disorders. It is a complex trait and both genetic and environmental factors have been implicated in its pathogenesis. There is growing evidence indicating that exposure to envi…

BACKGROUND: GnRH agonist and antagonist were developed to control the premature release of LH surge. There is some difference between two protocols. OBJECTIVE: We compared the outcome of frozen-thawed embryo transfer in infertile women who…

BACKGROUND: Determination of oocyte fertilization and embryo quality are one of the most important purposes in ART cycles. Follicular fluid provides an important microenvironment for development of oocytes and some biochemical characteristi…
