Sperm survival and heterogeneity are correlated with fertility after intrauterine insemination in superovulated ewes.
Efficient animal production involves accurate estimations of fertilizing ability. One key factor is the plasma membrane of the sperm cell, which is actively involved in the cascade of events before oocyte fusion. Many methods are used to analyze the characteristics of this membrane, including partition in aqueous two-phase systems which is an efficient method to analyze sperm surface changes ac...
متن کاملRam sperm selection by a dextran/swim-up procedure increases fertilization rates following intrauterine insemination in superovulated ewes.
The objective of this study was to compare the efficacy of 2 dextran/swim-up media to increase the sperm quality parameters and the maintenance of these parameters at 15 degrees C and 30 degrees C over 6 hours. Additionally, this study examined whether differences in sperm quality reflect different reproductive efficiencies following intrauterine insemination in superovulated ewes. The study in...
متن کاملA Comparison of Transcervical and Laparoscopic Intrauterine Artificial Insemination Techniques on Reproductive Performance of Ewes
In all domestic species, acceptable pregnancy rates with frozen-thawed semen are only achievable with intrauterine insemination. Unlike the cow and the goat, the cervix of the ewe is a formidable barrier to penetration for transcervical intrauterine insemination not only due to the physical size of the canal and a narrow luminal diameter (even at estrus), but also due to it’s caudally facing, e...
متن کاملFertility of Ewes after Intrauterine Insemination with Frozen Semen
In an experiment involving the artificial insemination of 312 Merino ewes, fertilization, early (18 day), and late (100 day) pregnancy rates were examined after intrauterine insemination with frozen semen using a laparoscope. Oestrus was synchronized in ewes by progestagen sponge/PMSG treatment. After cervical insemination of fresh semen (control) 55 hrs after sponge removal, the fertilization,...
متن کاملA randomised prospective trial of intrauterine insemination versus timed intercourse in superovulated cycles with clomiphene.
BACKGROUND & OBJECTIVES Despite its wide use, the benefits of intrauterine insemination (IUI), its over timed intercourse (TI) in couples with unexplained infertility is a matter of debate. Studies in Indian couples with unexplained infertility showing benefit of IUI over TI are not available. The present study was done with the objective of comparing TI and IUI with husband's sperm in couples ...
