BACKGROUND: Establishment of viable pregnancy requires embryo implantation and placentation. Ectopic pregnancy (EP) is a pregnancy complication which occurs when an embryo implants outside of the uterine cavity, most often in a fallopian tu…

BACKGROUND: Endometriosis is a chronic gynecological disease resulting from complex interactions between genetic, hormonal, environmental and oxidative stress and intrinsic inflammatory components. The aim of this study was to investigate t…

BACKGROUND: Controlled ovarian stimulation (COH) with intrauterine insemination (IUI) is commonly offered to infertile couples with patent fallopian tubes because it is simple, non-invasive and cost-effective technique. Another non-invasive…

BACKGROUND: To investigate the expression of Beclin-1 mRNA and protein in eutopic and ectopic endometrium of women with and without endometriosis, and evaluate the association of Beclin-1 protein expression and serum CA125 levels in the end…

BACKGROUND: Despite the meager role of the masculine agent in infertility (the low number of infertile men than women infertile), there are men whose wives are unable to become pregnant due to the absence of sperm, decreased numbers of sper…

BACKGROUND: We sought to determine the association between factors that affected clini- cal pregnancy and live birth rates in patients who underwent in vitro fertilization (IVF) and received intracytoplasmic sperm injection (ICSI) and/or la…

Until 2000 it was believed that gonadotropin-releasing hormone (GnRH) was the sole regulator of hypophyseal gonadotropes. In 2000, the discovery of a gonadotropin inhibitory hormone (GnIH) initiated a revolution in the field of reproductive…

Genitourinary tuberculosis is a common extrapulmonary manifestation of tuberculosis. Taking into consideration that genitourinary tuberculosis may be associated with a diversity of presentations, its diagnoses may be difficult. A young woma…

Severe pelvic infections following ultrasound-guided transvaginal oocyte retrieval (TVOR) are rare but challenging. Ovarian abscess formation is one of the consequences and management of such cases as highly debated in pregnant patients. In…

BACKGROUND: The aim of this study was to determine the relationship between marital violence and distress level among women with a diagnosis of infertility. MATERIALS AND METHODS: In this prospective randomized study, a total of 180 patien…

BACKGROUND: One of the most important factors affecting success rates in assisted reproductive techniques (ART) besides the number of oocytes retrieved and high quality embryos derived from them is the technical aspects of embryo transfer. …

BACKGROUND: Our objective was to evaluate the effect of ovarian endometrioma on ovarian stimulation outcomes in in vitro fertilization cycles (IVF). MATERIALS AND METHODS: In this prospective cohort study, we followed 103 patients who unde…

BACKGROUND: Although the risk factors of ectopic pregnancy have been determined in previous studies, the main risk factors of ectopic pregnancy are different in various countries due to different cultural and social characteristics. Determi…

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…

Placenta percreta is a rare complication potentially fatal to fetus and the mother. We present here a 41-year-old female patient who underwent curettage for incomplete abortion at 6(th) week of pregnancy. She had persistent vaginal bleeding…

BACKGROUND: To evaluate the involvement of immune abnormality in patients with idiopathic premature ovarian insufficiency (POI). In addition to the known etiology, autoimmune disorders may be a pathologic mechanism for POI. MATERIALS AND M…

BACKGROUND: This study evaluated the impact of body mass index (BMI), total calorie intake and physical activity (PA) as energy expenditure related factors on oxidative stress (OS) in follicular fluid (FF). MATERIALS AND METHODS: This pros…

Ovarian pregnancy is a rare form of extra uterine pregnancy. Serous cyst adenoma is a benign variant of epithelial cell tumors of ovary. The coexistence of a cyst adenoma with an ovarian pregnancy in the same ovary is extremely rare. Some s…

BACKGROUND: The objective of this retrospective cohort study was to evaluate whether the length of pituitary blockage with gonadotrophin-releasing hormone (GnRH) antagonists or the stimulation period influence intracytoplasmic sperm injecti…

BACKGROUND: To determine the correlates and the prevalence of infertility in a group of women. MATERIALS AND METHODS: This cross-sectional study was carried out on 570 subjects aged 18-49 years in a town of western Turkey between July and …

BACKGROUND: Poor ovarian response (POR) to gonadotropin stimulation has led to a significant decline in success rate of fertility treatment. The immune system may play an important role in pathophysiology of POR by dysfunctions of cytokines…

BACKGROUND: Adiponectin is one of the most important adipokines secreted from fatty tissue that has a direct inhibitory effect on the development of cancer cells. Adiponectin plays an important role in human reproduction system and fertilit…

BACKGROUND: The present study aims to explore the significance of the expression of growth hormone-releasing hormone (GHRH) and its receptor splice variant 1 (GHRHSV1) in endometriosis (EM). MATERIALS AND METHODS: In this research paper 80…

BACKGROUND: The transfer of cryopreserved embryos can be timed with ovulation in a natural cycle or after artificially preparing the endometrium with exogenous hormones. Progesterone is essential for the secretory transformation of the endo…
