The effect of antisperm antibodies measured by direct mixed agglutination reaction on in vitro fertilization rate

Background: Although in vitro fertilization (IVF) has been found to bypass the inhibitory effect of high levels of antisperm antibodies on sperm motility, fertilization rates are reduced in approximately 40% of the attempts. In this study, we investigated the relationship between antisperm antibodies measured by the direct mixed agglutination reaction (MAR) and the fertilization rate in inferti...

Replete vitamin D stores predict reproductive success following in vitro fertilization.

OBJECTIVE To determine whether 25OH-D levels in the follicular fluid (FF) of infertile women undergoing IVF demonstrate a relationship with IVF cycle parameters and outcome, hypothesizing that levels of 25OH-D in body fluids are reflective of vitamin repletion status. DESIGN Prospective cohort study. SETTING Academic tertiary care center. PATIENT(S) Eighty-four infertile women undergoing ...

Impact of The Endometrioma on Ovarian Response and Pregnancy Rate in In Vitro Fertilization Cycles

The effect of varicocele ligation on oocyte fertilization and pregnancy after failure of fertilization in in vitro fertilization-embryo transfer.

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...
