C

grade

Both eCG alone and eCG combined with buserelin significantly improve embryo production in weaned sows without compromising embryo quality.

Approximately 48% increase in ovulatory response (37 vs 25 corpora lutea; P < 0.001).

summary

C

grade

No significant differences in ovulation timing or reproductive performance were found among treatments in sows, suggesting limited impact on FTAI protocols.

No significant differences in reproductive outcomes were detected among treatments.

summary

C

grade

Buserelin supplementation at the first insemination may improve farrowing rates in commercial swine herds, but it does not appear to significantly affect litter size.

Farrowing rate with buserelin was 90.1% vs. 86.9% for control, p=0.009.

summary

C

grade

Buserelin permeated over 61% of porcine endometrial tissue in 8 hours, with early enhancement from diluted semen but no overall difference in cumulative diffusion.

Overall percentage of buserelin permeation was 61.3 ± 7.8% in the buserelin group and 62.2 ± 4.6% in the buserelin plus diluted semen group, p = 0.840.

summary

C

grade

Buserelin may improve ovulation-embryo synchrony in donor sows compared to hCG without compromising embryo yield and quality.

Higher proportion of BU-treated sows presenting embryos at the blastocyst stage compared with hCG-treated sows (p=0.0051).

summary

C

grade

Fertirelin appears to be the most effective GnRH analogue for ovulation induction in rabbits, outperforming buserelin and deslorelin.

Fertirelin achieved ovulation and delivery rates equivalent to the intramuscular control at a dose of 1 μg.

grade

The study indicates a low risk of Q-fever from local animals in Hong Kong, with no active C. burnetii infections detected.

0% C. burnetii DNA detected in 866 animals.

summary

C

grade

The endometrium's ability to act as a biosensor during pregnancy is influenced by the developmental potential of the embryo, as shown by differences in gene expression and miRNA cargo.

C

grade

The Co-synch protocol resulted in significantly higher pregnancy rates compared to the Ovsynch protocol in Anatolian buffalo heifers.

Pregnancy rates were 30% and 75% in the Ovsynch and Cosynch groups, respectively (P<0.05).

summary

D

grade

Buserelin has been associated with higher rates of gastrointestinal and psychiatric adverse events compared to other long-acting GnRHa, particularly in adults.

Not reported in abstract.

summary

C

grade

Administering buserelin 34 hours after progesterone device removal improves ovulation synchrony in dairy cows but does not significantly enhance pregnancy rates per artificial insemination.

Cows in the EC-GnRH34 group ovulated at 60.4 ± 3.8h, P = 0.03.

summary

B

grade

Routine measurement of LH levels post-GnRH trigger does not predict mature oocyte yield in women with PCOS undergoing IVF/ICSI cycles.

Mean LH level at 12 hours post trigger was 34.05 (SD 23.07 IU/L, range: 0.9 to 134.4 IU/L).

summary

B

grade

Pulsatile GnRH therapy induced ovulation in women with functional hypothalamic amenorrhea, with significant hormonal changes observed primarily in those without polycystic ovarian morphology.

Median AMH levels at baseline were 6.21 ng/ml in the PCOM group vs 1.7 ng/ml in the non-PCOM group, p<0.001.

summary

B

grade

Gn stimulation duration significantly affects oocyte maturation, with an optimal window of 8-10 days linked to better pregnancy outcomes.

Adjusted OR 1.07 for oocyte maturation per day of Gn stimulation, 95% CI 1.05-1.09, p<0.001.

summary

B

grade

This study suggests that a combination of GnRH-a, hysteroscopic surgery, and LNG-IUS may be a safe option for patients with adenomyosis who do not respond well to HIFU, but further research is needed to confirm these findings.

Median NPV ratio following HIFU ablation was 22.2% (IQR: 12.0%-36.2%)
