Abnormal centriolar biomarker ratios correlate with unexplained bull artificial insemination subfertility: a pilot study
The mechanisms underlying male infertility are poorly understood. Most mammalian spermatozoa have two centrioles: the typical barrel-shaped proximal...

Transcervical artificial insemination in the brown brocket deer (Subulo gouazoubira): a promising method for assisted reproduction in deer
The present study aimed to test the efficiency of transcervical artificial insemination techniques with cervical immobilization (TCAI-CI) or cervical...

Vaginal and vestibular electrical resistance as an alternative marker for optimum timing of artificial insemination with liquid-stored and frozen-thawed spermatozoa in sows
Development of a pen-side test to objectively determine the ideal time for artificial insemination (AI) in the sow would save producers time and...

Artificial insemination and parthenogenesis in the whitespotted bamboo shark Chiloscyllium plagiosum
Non-lethal methods for semen collection from elasmobranchs to better understand species reproduction has accompanied the development of artificial...

Compensability of an enhanced incidence of spermatozoa with cytoplasmic droplets in boar semen for use in artificial insemination: a single cell approach
This single cell study aimed to clarify whether an elevated incidence of sperm with a retained cytoplasmic droplet (CD) can be compensated by a...

Shifts in uterine microbiome associated with pregnancy outcomes at first insemination and clinical cure in dairy cows with metritis
Objectives were to assess differences in uterine microbiome associated with clinical cure and pregnancy outcomes in dairy cows treated for metritis....

The role of peak serum estradiol level in the prevention of multiple pregnancies in gonadotropin stimulated intrauterine insemination cycles
The objective was to assess whether the measurement of serum estradiol (E 2 ) level on trigger day in controlled ovarian stimulation with intrauterine...

An artificial intelligence algorithm for automated blastocyst morphometric parameters demonstrates a positive association with implantation potential
Blastocyst selection is primarily based on morphological scoring systems and morphokinetic data. These methods involve subjective grading and...

Pregnancy rates after slow-release insemination (SRI) and standard bolus intrauterine insemination (IUI) – A multicentre randomised, controlled trial
This multicentre, randomised, controlled cross-over trial was designed to investigate the effect of intra-uterine slow-release insemination (SRI) on...

Effects of dietary n-3-PUFA supplementation, post-insemination plane of nutrition and pregnancy status on the endometrial transcriptome of beef heifers
Supplementation of cattle diets with n-3 -polyunsaturated fatty acids (PUFA) can improve reproductive efficiency. Conversely, short-term fluctuations...

In vivo measurement of pH and CO2 levels in the uterus of sows through the estrous cycle and after insemination
The pH–CO 2 –HCO 3 − system is a ubiquitous biological regulator with important functional implications for reproduction. Knowledge of the physiological...

Investigating the genetic determination of duration-of-fertility trait in breeding hens
The duration-of-fertility (DF), which was defined as the number of days when breeding hens lay fertile eggs following copulation or artificial...

Sperm tendency to agglutinate in motile bundles in relation to sperm competition and fertility duration in chickens
A unique sperm behavior was observed in Egyptian chickens. Sperm showed a tendency to agglutinate forming motile thread-like bundles. Sperm...

Long-term artificial selection of Hanwoo (Korean) cattle left genetic signatures for the breeding traits and has altered the genomic structure
Indigenous Korean breeds such as Hanwoo (Korean) cattle have adapted to their local environment during the past 5000 years. In the 1980s, the...

Improved reproductive performance achieved in tropical dairy cows by dietary beta-carotene supplementation
Dairy farming in tropical climates is challenging as heat stress can impair reproduction in cows. Previous studies have demonstrated the beneficial...

Identification of large offspring syndrome during pregnancy through ultrasonography and maternal blood transcriptome analyses
In vitro production (IVP) of embryos in cattle can result in large/abnormal offspring syndrome (LOS/AOS) which is characterized by macrosomia. LOS...

Validation of the volumetric flow cytometry for bovine sperm concentration
Sperm concentration is a stronghold of the andrological evaluation and the production of insemination doses. The use of haemocytometers, although...

Sex ratio shift after frozen single blastocyst transfer in relation to blastocyst morphology parameters
The sex ratio shift was observed in peoples who underwent ART treatment. Moreover, there is limited evidence on differences in sex ratio between...
