background: various approaches have been used in the attempts to improve the quality of frozen–thawed mouse sperms. according to literatures, it seems that hyaluronic acid (ha) has an important role on the permeability and motility of sperms and their interaction with gametes. objective: for evaluation of ha supplementation on sperm characteristics and fertilization capability, we investigated ...

background: although the uterine fibroids are common, their influence on fertility remains controversial. the association of submucosal fibroid with subfertility is well recognized, but debate persists as to whether intramural fibroids can cause infertility and the evidence for its effect on pregnancy in cycles of assisted conception remains unclear. objective: the purpose of present study was ...

s:1858:"Background: Infertility is defined as inability in pregnancy after one year of regular intercourse without using contraceptive methods. Approximately15-10% of couples in childbearing appears infertile. It is the cause of infertility in men and women and infertility treatment depends on type of failure and is one of the methods of treating infertility in vitro fertilization. This researc...

background: implantation remains a limiting step in ivf/icsi. endometrial injury isa promising procedure aiming at improving the implantation and pregnancy rates after ivf/icsi. objective: the aim of this study was to evaluate the effect of endometrial injury induced in precedingcycle on ivf/icsi outcome. materials and methods: four hundred patients undergoing their first ivf/icsi cycle in two ...

Our meta-analysis analyzed the relationship between levels of reactive oxygen species (ROS) and fertilization rate after in vitro fertilization (IVF), and showed a statistically significant correlation between the ROS levels and the IVF fertilization rate (estimated overall correlation -0.374 [95% CI, -0.520, -0.205]). We conclude that ROS has a statistically significant effect on the fertiliza...

background: repeated in vitro fertilization (ivf) failure together with ovarian hyperstimulation syndrome (ohss) is one of the distressing situations leading couples to search for alternative treatment options. for such patients with polycystic ovarian syndrome (pcos) who have experienced ovarian hyperstimulation syndrome, mild ovarian stimulation with in vitro oocyte maturation could be a prom...

Although varicocelectomy is generally believed to improve semen quality and the hamster egg penetration assay, these parameters do not correlate well with in vitro fertilization (IVF) success. The effect of varicocelectomy on IVF of human oocytes was examined on thirteen couples with normal female fertility, but severe oligozoospermia and the presence varicocele in the males with failure of fer...

In vitro fertilization (IVF) is a process by which an egg is fertilised by sperm outside the body: in vitro . The process involves monitoring and stimulating a woman's ovulatory process, removing an ovum or ova (egg or eggs) from the woman's ovaries and letting sperm fertilise them in a liquid in a laboratory. The fertilised egg (zygote) is cultured for 2–6 days in a growth medium and is then i...

background: research supports that in vitro fertilization causes anxiety and that anxiety can continue into the resulting pregnancy. most women who have ivf will have a less invasive treatment for infertility prior to ivf; however, it is unclear if specific less invasive treatment cycles impact anxiety that is experienced in the pregnancy resulting from ivf. methods: a prospective study was con...
