BACKGROUND: Preterm labor is one of the main causes of neonatal mortality and its treatment is still challenging. OBJECTIVE: The study aimed to compare the effectiveness of nifedipine (Nif) with and without sildenafil citrate (SC) for the …

BACKGROUND: Endometriosis is a disease that affects women throughout their sexual life. Sexual health is, therefore, a major concern for these women. OBJECTIVE: This study aimed to assess the effects of the sensate focus technique and posi…

BACKGROUND: Ectopic pregnancy (EP) is defined as embryo implantation in a location other than the uterine cavity. OBJECTIVE: We aimed to evaluate the expression of several genes, which may play a role in EP, in the ampulla region of fallop…

BACKGROUND: Advances in cell culture media have led to a trend of embryo transfer from the early cleavage stages to blastocyst stage. OBJECTIVE: The study aims to compare the effects of fresh embryo transfer in cleavage and blastocyst stag…

BACKGROUND: Individualized assisted reproductive techniques (ART) can improve ART outcomes. Some studies suggested using insulin-like growth factor-1 (IGF-1) level on cycle day 2 for individualized ART. OBJECTIVE: To investigate the relati…

BACKGROUND: Repeated implantation failure (RIF) affects 15% of women of reproductive age. There is a high endometrial expression of both estrogen receptors and progesterone receptors (PRs) during the window of implantation in women with RIF…

BACKGROUND: Coronavirus disease 2019 (COVID-19) was detected in the throat, urine, and feces but has little evidence documented of sexual transmission. OBJECTIVE: Here, we aimed to diagnose the presence of COVID-19 in vaginal fluids and me…

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…

BACKGROUND: Infertility affects around 10-15% of couples worldwide and is both a social and medical problem. Parental consanguinity is considered to reduce fertility reserve. Consanguineous marriages, especially first cousin marriages, are …

BACKGROUND: In 15% of all clinical pregnancies, a miscarriage can occur, but the exact cause of this phenomenon is not fully understood. However, it is believed that a faulty placenta, which triggers an inflammatory response in the mother's…

BACKGROUND: There is no agreement on which of the 2 gonadotropin-releasing hormone (GnRH) agonist protocols are the most efficient, neither there is any consensus on which one yields a better clinical pregnancy percentage. OBJECTIVE: The p…

BACKGROUND: Selecting a suitable and preferable method for endometrial preparation in frozen embryo transfer (FET) cycles for women with adenomyosis is still challenging in infertility treatment. OBJECTIVE: To compare 2 artificial endometr…

BACKGROUND: In some societies, childbearing is a part of women's identity and infertile women are under a great amount of pressure from others. OBJECTIVE: This study aims to evaluate the relationship between infertility factors and sexual …

Hysterosalpingography (HSG) is a practical and reliable imaging method to evaluate the cervical canal, uterine isthmus, uterine cavity, and fallopian tubes. Using HSG, opaque pathologies outside of contrast media can be detected as well as …

BACKGROUND: Fewer studies were on micronutrient intake in women with endometriosis, and the etiology of endometriosis remains unclear between dietary micronutrients and the risk of endometriosis. OBJECTIVE: This study aimed to investigate …

BACKGROUND: Endometriosis is a challenging gynecological disease and a debilitating condition that profoundly affects the individual's quality of life. Besides pathological confirmation, diagnostic laparoscopy has been internationally accep…

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: Early diagnosis and appropriate treatment of endometriosis are vital and may prevent subsequent complications. OBJECTIVE: To investigate the diagnostic accuracy of transvaginal ultrasound sonography (TVUS) and transrectal ultra…

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…

BACKGROUND: Primary ovarian insufficiency (POI) is a rare disease clinically characterized by ovarian follicles depletion or dysfunction and menopause before the age of 40 yr as the cut-off age for POI. It is a complex disease, and its etio…

BACKGROUND: Declining fertility in a woman of advanced age is associated with a depletion in ovarian reserve as well as declining oocyte and embryo quality. Determining the predictors of embryo quality may assist in stimulation target and c…

BACKGROUND: Infertility is one of the issues affecting sexual function (SF). Infertility is also one of the complications of polycystic ovary syndrome (PCOS) and endometriosis. OBJECTIVE: This research seeks to assess and compare SF and th…
