Insights
Accessory sex gland growth in prepubertal Beetal kids was studied using ultrasonography. The prostate showed significant growth first, followed by seminal vesicles and bulbourethral glands at different ages.
Area of Science:
- Veterinary Anatomy
- Reproductive Biology
- Diagnostic Imaging
Background:
- Accessory sex glands are crucial for male reproductive health.
- Understanding their growth patterns in young animals is vital for assessing reproductive maturity.
- Prepubertal growth dynamics of these glands in goats are not well-documented.
Purpose of the Study:
- To investigate the growth trajectory of accessory sex glands in prepubertal Beetal kids.
- To determine the age-specific dimensional changes in prostate, seminal vesicles, and bulbourethral glands.
- To establish a baseline for normal accessory sex gland development in this breed.
Main Methods:
- Two-dimensional ultrasonography was employed to scan accessory sex glands in six prepubertal Beetal kids.
- Measurements of gland dimensions were recorded bi-weekly from 2 weeks to 6 months of age.
- Statistical analysis utilized one-way ANOVA and Duncan's multiple range test for significance.
Main Results:
- All measured dimensions of accessory sex glands increased with age.
- The prostate gland exhibited significant width increases at 2, 10, and 20 weeks.
- Seminal vesicles and bulbourethral glands showed significant circumference increases at specific ages, with varying patterns between glands.
Conclusions:
- Significant growth did not occur concurrently across all three accessory sex glands.
- The prostate initiated significant growth around 10 weeks, followed by seminal vesicles at 14 weeks, and bulbourethral glands at 16 weeks.
- These findings provide insights into the sequential development of accessory sex glands in prepubertal goats.
Aim:
The present study was undertaken to study growth pattern of accessory sex glands in prepubertal kids from 2 weeks to 6 months of age using two-dimensional ultrasonography.
Materials And Methods:
The study was conducted on six Beetal kids. The scanning of accessory sex glands was done in standing position using rectal probe and measurements were recorded. Data collected were statistically analyzed using one-way ANOVA followed by Duncan multiple range test was performed using the SPSS (16.0) system for windows.
Results:
With the advancement of age all the dimensions of glands increased. Both the lobes of prostate gland showed an increase in width with advancement of age. Width of prostate above the urethra (W1) showed a significant increase at 2, 10, and 20 weeks of age, whereas non-significant increase from 2 to 8, 10 to 19, and 20 to 24 weeks of age was recorded. Width of prostate below the urethra (W2) showed a significant increase at 20 weeks of age, whereas non-significant increase was recorded during rest of period of growth. Left and right bulbourethral gland showed a similar pattern of growth with the advancement of age. The circumference dimensions increased significantly at 2, 16, 20, and 21 weeks of age for both glands. The increase was non-significant from 4 to 14, 16 to 19, and 20 to 23 weeks of age. The same pattern was observed for left and right seminal vesicular gland.
Conclusion:
Significant growth in three accessory sex glands in prepubertal kids was not observed at the same age. The trend observed was that the prostate was the first gland to show significant growth at 10 weeks of age followed by a significant increase in seminal vesicles and bulbourethral gland at 14 and 16 weeks of age, respectively.
