OBJECTIVE: For successful embryo implantation in women with high pulsatility, uterine vascular resistance and pulsatility must be reduced. We examined the effects of amlodipine on uterine pulsatility index (PI), resistance index (RI), and e…
BACKGROUND: Polycystic ovary syndrome (PCOS) is a leading cause of anovulatory infertility. In women undergoing frozen embryo transfer, the method of endometrial preparation (hormone replacement therapy [HRT] or mild ovarian stimulation [MO…
BACKGROUND: Background: Infertility is a global public health concern, and controlled ovarian stimulation (COS) plays a crucial role in assisted reproductive technologies (ART) by facilitating the retrieval of multiple oocytes. This single-…
BACKGROUND: Endometriosis is a chronic inflammatory disease affecting about 10% of women of reproductive age. Endometrioma is the most common presentation of endometriosis in ovaries. OBJECTIVES: Herein, the authors study the effect of the…
BACKGROUND: Growth hormone (GH) is a potential treatment in the assisted reproductive technology (ART) to improve endometrial receptivity and thickness. In the current study, we investigated the effect of the intrauterine administration of …
BACKGROUND: Oral progesterone is recommended as an alternative to gonadotropin-releasing hormone (GnRH) agonists and antagonists to prevent luteinizing hormone (LH) surge in assisted reproductive technology (ART) cycles. However, there are …
BACKGROUND: Infertility is one of the major social issues. Due to the asymptomatic cervical infection associated with Staphylococcus aureus (S. aureus), the majority of patients remain undiagnosed. The present study intended to assess the f…
OBJECTIVES: The cyclical changes in proliferation and differentiation of endometrial cells are regulated by estrogen and progesterone via modulating Wnt/β-catenin signaling. Imbalance in the expression of estrogen and progesterone receptors…
BACKGROUND: Vitamin D in complex with its receptor by regulating gene expression, endometrium immune response and stimulation of endometrium decidualization can be involved in implantation. So, it seems that the amount of vitamin D in folli…
BACKGROUND: Paraoxonase-3 (PON3), as a high density lipoprotein (HDL)-associated lactonase, is capable of preventing the oxidative modification of low density lipoprotein (LDL). PON3 activity in follicular fluid (FF) is three times more tha…
BACKGROUND: More than 40% of infertilities are due to endometriosis. Ultrustructural and histochemical study of endometrium will help to clarify the etiology of endometriosis. OBJECTIVE: The aim of the present study was to investigate the …
