Journal ArticleDOI
TL;DR: This review summarizes recent data highlighting the role of progesterone in determining oocyte quality and embryo development in cattle.

195 citations


Journal ArticleDOI
TL;DR: It is mandatory to define a set of CD markers which can be uniformly applied for the identification of equine MSC, as the expression of certain adult stem cell markers may differ between species.

171 citations


Journal ArticleDOI
TL;DR: GH promoted in vitro growth and maturation of goat preantral follicle oocytes and enabled production of an embryo, apparently the first to produce a caprine embryo by in vitro fertilization of oocytes derived from preantrals follicles grown in vitro.

146 citations


Journal ArticleDOI
TL;DR: It is demonstrated that individual variation in oocyte yield is associated with embryo production and pregnancy rates and there was no significant effect of the number of OPU sessions per donor on mean numbers of oocytes produced.

136 citations


Journal ArticleDOI
C.C. Love1
TL;DR: Sperm motility variables associated with an increase in PC and FCP included total, progressive, and rapid sperm motility, and increased path and progressive velocity, which was the only fertility measure able to discriminate among high, average, and low fertility groups.

135 citations


Journal ArticleDOI
TL;DR: A lower local level of expression of pro-inflammatory cytokines in the endometrium soon after calving might impair activation of inflammation and clearance of bacteria, and lead to development of endometritis.

130 citations


Journal ArticleDOI
TL;DR: Using only 2.5% FCS and the addition of PES from Day 4, increased the survival of IVP embryos after vitrification, and embryo quality, represented by the fresh apoptosis rate, was better than lipid content for predicting embryo survival after vitrified embryos.

129 citations


Journal ArticleDOI
TL;DR: Current developments in the technology of freezing stallion sperm, paying special attention to the molecular lesions that spermatozoa suffer during freezing and thawing, include osmotic stress, oxidative damage, and apoptotic changes.

127 citations


Journal ArticleDOI
TL;DR: Virulence factors in E. coli associated with adherence may be important in metritis and PVD, and there are emerging data that cervicitis exists both concurrent with and separate from endometritis.

115 citations


Journal ArticleDOI
TL;DR: This review considers the use of statistical techniques for clustering CASA data, their challenges and possibilities, and there are many clustering approaches potentially useful for grouping sperm motility data; some options may be more appropriate than others.

110 citations


Journal ArticleDOI
TL;DR: This review discusses the distinct aspects of follicular development in lactating dairy cows and the methodologies that have been utilized in the past two decades in order to manage the dominant follicle during synchronization of ovulation and timed AI programs.

Journal ArticleDOI
TL;DR: Differences in sperm motility were related to n-3 PUFA content in the sperm plasma membrane and extracellular antioxidants in seminal plasma which protect sperm plasma membranes from lipid peroxidation during periods of oxidative stress.

Journal ArticleDOI
TL;DR: Adding L-carnitine during IVM/IVC improved developmental potential of porcine oocytes, and also the quality of parthenogenetic embryos, probably by accelerating nuclear maturation, and preventing oxidative damage and apoptosis.

Journal ArticleDOI
TL;DR: Bioinformatic analyses revealed that messenger RNA targets of the differentially expressed miRNAs encode proteins previously described to play roles in sperm function, and their changes as associated with morphology and motility signify a critical biological function.

Journal ArticleDOI
TL;DR: The CB is recommended to improve the diagnosis of subclinical endometritis in the mare compared to the US alone as currently used routine method, and a combination of a bacteriological and a cytological examination of a CB sample improved the diagnostic performance in subfertile mares.

Journal ArticleDOI
TL;DR: Cows in the highest quartile for PMN% at both D28 and D42 had lower pregnancy rates, took longer to conceive, and had a lower milk yield than those in the lower PMN%.

Journal ArticleDOI
TL;DR: Sperm cells at the spermiogenic and meiotic stages of development are more susceptible to heat stress, together with subtle changes in sperm head shape, which can be detected by FHA but not by conventional semen analysis.

Journal ArticleDOI
TL;DR: Cows that displayed estrus had better ovarian responses (i.e., larger follicles at TAI, a greater ovulation rate, larger CL, and greater P4 concentrations) following an estradiol/P4-based synchronization protocol.

Journal ArticleDOI
TL;DR: FGF receptor activation was important for optimal blastocyst formation and FGF2 supplementation increased bovine blastocysts formation when provided at high concentrations, according to the overall goal.

Journal ArticleDOI
TL;DR: The size of the breed, the age of the bitch and the method of mating were found to influence litter size in purebred dogs when controlling for breed, with the size ofThe breed as the strongest determinant.

Journal ArticleDOI
TL;DR: It is demonstrated that sterilised egg yolk plasma has the potential to replace Egg yolk in stallion freezing extender and led to the development of a ready-to-use extender called INRA-Freeze(®) (IMV-Technologies, France).

Journal ArticleDOI
TL;DR: In this paper, the authors focus on the importance of orchestrating donor and recipient management to assure better logistics of procedures to achieve more desirable results with embryo collection and transfer, and provide clear evidence that the use of FTAI in superstimulated donors and FTET in embryo recipients eliminates the need to detect estrus with satisfactory results.

Journal ArticleDOI
TL;DR: It is concluded that SP proteins that bound to the sperm membrane were conserved among ram breeds, and that when added to frozen/thawed semen (along with an energy source), they repaired ram sperm damage and enhanced sperm motility.

Journal ArticleDOI
TL;DR: Adding GSH, SOD or CAT did not increase the total antioxidant capacity of semen, nor did it enhance the quality of the post-thaw sperm, but maintenance of ram semen at 5 °C for 12 h prior to cryopreservation reduced membrane damage of frozen-thawed sperm.

Journal ArticleDOI
TL;DR: A survey on all data published so far on Interspecific Somatic Cell Nuclear Transfer, including abstract communication in international meetings, and possible solutions for the successful application of somatic cell nuclear transfer to endangered animals are put forth.

Journal ArticleDOI
TL;DR: GnRH immunocontraception is an ideal candidate for further development for feral cat control and non-painful but persistent late-onset granulomatous injection site masses appeared 2 y after initial vaccination in five cats.

Journal ArticleDOI
TL;DR: Data is examined that provides strong support for the clinical translation of ASC for bone regeneration and the use of scaffolds in combination with ASC and growth factors provides a valuable tool for guided bone regeneration, especially for complex anatomic defects.

Journal ArticleDOI
TL;DR: Results suggest that the boar-sperm nuclear structure is heterogeneous suggesting the existence of a zonated pattern, differing in their total DNA density and the compactness of the precise nucleoprotein structures present in each zone.

Journal ArticleDOI
TL;DR: AMH was a useful biomarker for detection of granulosa-cell tumors in mares and both AMH and AMH receptor (AMHR2) immunolabeling and expression were detected by immunohistochemistry in the tumor and cyst fluid obtained from mares with GCTs.

Journal ArticleDOI
TL;DR: Improvements in P/AI with delayed time of AI were possible (Experiments 1 and 3), and seemed achievable when breeding at 60 h following progestin implant removal, compared to the standard 54 h normally used in TAI protocols.
