background: conventional ivf and icsi are two common techniques to achieve fertilization. ivf has long been used for treatment of infertility, although it is not an effective treatment in severe male infertility. the use of icsi has been expanded in severe male factor and fertilization failure after ivf cycle. in spite of the widespread use of icsi in patients with non-male factor infertility, ...

background: endometrial secretion analysis is a non-invasive and promising method in evaluation of endometrial receptivity. objective: the aim of the present study was to assess the relationship between the success rate of ivf procedures and some endometrial secretion cytokines, including interleukin-1β (il-1β), tumor necrosis factor (tnf-α), interferon gamma-induced protein 10 (ip-10), and mon...

a study was conducted to investigate the effect of follicular size (small,

background: infertility is an increasing medical and social problem. in vitro fertilization (ivf) has become a common and accessible treatment for a wide variety of indications that have variable outcomes. natural killer (nk) cells have been identified as relevant immunological factors involved in reproductive success or failure. objective: the aim of this study was to compare the percentage of...

background: pyridaben, a pyridazinone derivative, is a new acaricide and insecticide for control of mites and some insects such as white flies, aphids and thrips. objective: this study was designed to elucidate how pyridaben can affect the sperms' morphological parameters, its dna integrity, and to estimate the effect of various quantities of pyridaben on in vitro fertilization rate. materials ...

there has been a dramatic rise in the use of assisted reproductive technologies (art), including in vitro fertilization (ivf) throughout the world over the past three decades. because they represent >1% of the birth cohorts in many developed countries, much attention is being paid to the health and well-being of art children. children born after assisted reproductive techniques (art) have an in...

the main factors affecting pregnancy and implantation rates are uterine receptivity, embryo quality, and transfer efficiency. embryo transfer (et) is the last step of critically important procedure of in vitro fertilization (ivf) and probably the least successful step in assisted reproductive technology (art) treatment cascade; though simple in most of the cases, it may pose to be the most diff...

background: ovarian pregnancy constitutes 0.15-3% of all ectopic pregnancies. the incidence of ectopic pregnancy is on the rise owing to evolution in assisted reproductive techniques (art). the incidence reported following in vitro fertilization (ivf) or embryo transfer (et) is 0.27% per clinical pregnancy. case: we present a case of a 13-weeks ovarian pregnancy following ivf-et and through a r...

background: supplementation of luteal phase with progesterone is prescribed for women undergoing routine ivf treatment. objective: the objective of this study was to compare the efficacy of three types of progesterone on biochemical, clinical and ongoing pregnancy rates and abortion and live birth rates. materials and methods: a prospective randomized study was performed at royan institute betw...

background: endometriosis is a common hormone-dependent gynecologic disease with a high recurrence. laparotomy or laparoscopy is the standard surgery for the large endometrioma. also, sclerotherapy is basically used to treat different diseases one of which is endometrioma. objective: the study was designed to assess the value of transvaginal ultrasound-guided ethanol sclerotherapy in patients w...
