background: controlled ovarian hyper stimulation coh/iui represents a therapy applicable to a wide variety of infertility diagnosis with no significant mechanical distortion of pelvic viscera. identified variables influenced in intra uterine insemination include: age, cause of infertility, sperm number, motility and normal percentage, use of gonadotropine and number of attempts at iui. the role...

vascularization of the follicle may play a role in its maturation and aspirin seems to increase this vascularization.in this investigation we have studied the effects of low-dose aspirin on ovarian and uterine response, implantation and pregnancy rates in patients undergoing intracytoplasmic sperm injection (icsi). this prospective semirandomized, double-blind, placebo-controlled study was unde...

background: in spite of the great progress in assisted reproductive techniques ( art) and although good quality embryos are transferred pregnancy rates have remained around 30%-35% due to low implantation rates. objective: the aim of this study was to assess and compare the effects of administrating indomethacin or hyoscine suppositories prior to embryo transfer on the pregnancy rate in art cyc...

background: frozen- thawed embryo transfer is an essential part of art treatment and outcomes of this procedure are associated with several clinical factors. several studies have showed an increase level of ivf outcomes in women with sufficient vitamin d. objective: whether treatment of vitamin d insufficiency can improve pregnancy rates in frozen-thawed embryo transfer cycles. materials and me...

introduction: from maturity to menopause, women are worried about pregnancy. abstinence from sex or use of pregnancy prevention methods are choices for them. as abstinence is impossible, the only remaining choice is use of pregnancy prevention methods. effective control of pregnancy is really essential for the health of mother and infant and also control of unplanned increase in population. reg...

background: c-reactive protein (crp) can be increased after hormonal stimulations. the changes of crp might affect the success of in-vitro fertilization (ivf). objective: the aim of this study was to determine the possible relationship between the serum crp level and outcome of controlled ovarian stimulation, and pregnancy rate in patients undergoing ivf or intra cytoplasmic sperm injection (ic...

hydrosalpins (dilatation of fallpian tube that can be seen by hysterosalpingogeraphy. laparoscocpy, and in severe cases by sonography) is one of the probable confounding factors of assited – reproduction therapy (art) outcomes. this cohort study is conducted to determine the effects of hydrosalpins on ivf-et outcomes. for this, of the total number of patients who had approached the infertility ...

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: embryo transfer (et) has traditionally been performed two days after oocyte retrieval. delaying transfer from day two to day three or four would allow for further development of the embryo might therefore optimize the selection of viable and best quality embryos for transfer and may be closer to the physiological time of the entry into the uterus than transfer on day two and might h...

background: embryo transfer has received little clinical attention and has been the most inefficient step in in-vitro fertilization (ivf). recent reports have suggested that an awareness of the position and length of the uterus during embryo transfer might be helpful in improving pregnancy rate. objectives: the main objective of the present study was to determine the relation between the length...
