“…These breeds were reported to have GSI values of 3.55 ± 0.52, 3.65 ± 0.41 and 3.75 ± 0.52 % respectively. The testicular sperm reserves per gramme testis in this study was similar to the values of 0.03-1.88 billion cells reported in Nigeria (Abba & Igbokwe, 2015), but higher than sperm reserves for Jordanian goat bucks (Omari et al, 2018). Daily sperm production (DSP) and daily sperm production per gramme testis (DSPG) in this study were higher than 3.32 ± 0.45 and 1.22 ± 0.01billion cells, reported for Nigerian adult WAD bucks (Bitto & Egbunike, 2006).…”

The West African Dwarf (WAD) goat has genetic potentials that can be exploited for improved goat production. However, their testicular morphometric parameters and sperm reserves in Ghana are not well known. A cross-sectional study was conducted at the Sabtiu Musah abattoir in Kumasi, Ghana, to evaluate the gross testicular morphometric parameters and sperm reserves in 10 indigenous WAD goats. The samples were stored on an ice chest and transported to the Regional Veterinary Laboratory for analysis on the day of collection. In the laboratory, the testes and epididymis were separated by dissection and then freed of all connective tissue and the Tunica albuginea. The weight, length, width and volume of the testis were determined. A segment of testicular parenchyma was incised and homogenized in a 20 ml normal saline solution. The resulting homogenate was stored in the refrigerator overnight and a filtered aliquot used for estimating spermatid concentration and sperm reserves. The weight, length, width, volume of the testis and the gonadosomatic index were 70.09 ±14.19 gm, 7.46 ± 0.52 cm, 5.08 ± 0.62, cm, 102.40 ± 29.40 ml and 5.09 ± 0.07%, respectively. The sperm reserves per the whole testis, sperm reserves per gramme testis, Daily Sperm production (DSP), and DSP per gramme testis of Ghanaian WAD bucks were 146.0 ± 50.95, 2.2 ± 0.62, 41.01 ± 14.3 and 0.62 ± 0.17 x109 spermatozoa, respectively. Indigenous West African Draft goats have a high potential for sperm production. It is recommended that further research be conducted on the semen quality parameters of this breed.

“…The gonado-somatic index (GSI, g/kg) was calculated by dividing the testis weight (g) by the body weight (kg). Likewise, the epididymo-somatic index (ESI, g/kg) was calculated by dividing the epididymis weight (g) by the body weight (kg) (Omari et al, 2018).…”

Testicular degeneration is an important cause of poor fertility in dogs, but there is little knowledge on its effects on spermatozoa in affected dogs. The study investigated the specific effects of unilateral testicular degeneration (UTD) on spermatozoal characteristics in the testis and epididymis. Ten sexually mature Nigerian indigenous breed of dogs, comprising 5 normal dogs and 5 dogs with UTD were used for the study. The testis and epididymis were removed via orchidectomy for morphological and histopathological evaluation. Sperm in the testis and cauda epididymis were analysed. The samples were grouped into four as N1 (normal right testis), N2 (normal left testis), ND (non-degenerated testis in UTD dogs), and D (degenerated testis in UTD dogs). Data were analysed using one-way ANOVA. There were significant decreases (p<0.001) in testes weight, length, width and volume, and the gonado-somatic index in the D testes compared to the contralateral ND and the N groups. The D group also had significantly lowered epididymal sperm total and progressive motility, viability and concentration (p<0.001), and a decreased testicular sperm concentration (p<0.01). Moreover, there was a decreased percentage (p<0.001) of morphologically normal sperm, with increased prevalence of sperm abnormalities in the D group compared to the other groups. In comparison with the N groups, the ND group had a significantly lowered (p<0.05) epididymal sperm progressive motility, with increased percentage (p<0.01) of sperm with proximal cytoplasmic droplets and looped tails. The findings demonstrated that UTD in dogs adversely affected spermatozoa in the testis and cauda epididymis. There was also evidence of compromised spermatozoa in the epididymis contralateral to the degenerated testis. Keywords: Canine; Epididymis; Spermatozoa; Testicular atrophy; Testicular degeneration

“…It has been reported in other species that there is a relationship between testicular morphometry and semen production and quality (Bath and Chaudhari, 2002;Bitto and Egbunike, 2006;Ugwu, 2009). There is also a consensus that information about gonadal and extra-gonadal sperm reserves appear to be important criteria for a thorough evaluation of male fertility (Obidi et al, 2008;Omari et al, 2018). Omari et al (2018) furthermore, noted that in areas with low technical and laboratory support for semen evaluation, livestock farmers may need a reference range of testicular sizes and sperm reserves to ascertain the reproductive efficiency of a male.…”

Livestock farmers may need a reference range of testicular sizes and sperm reserves to ascertain the reproductive efficiency of a male. However, information on camel testicular morphometry and gonadal sperm reserve in semi-arid Nigeria is scanty. This study was designed to provide information on testicular morphometry and gonadal and extragonadal sperm reserves of camels in the Sahel region of Nigeria. Testes of 15 mature and healthy camels were obtained after slaughter from the Maiduguri central abattoir. Scrotal circumference was measured on the live animal to the nearest centimetre. Weights of each testis, epididymis and its distinct parts and tunica albuginae were obtained to the nearest milligram. The length and width of each testis and the length of the distinct parts of the epididymis were measured to the nearest millimetre. Gonadal and extra-gonadal sperm reserves were also estimated. All data were subjected to descriptive statistics, paired sample t- test and correlation analysis. Scrotal circumference ranged from 24.00 to 49.00cm with an average of 38.59 ± 2.41cm. A high significant relationship (r = 0.69) between scrotal circumference and paired testis weight were observed. The left and right testes had similar sperm reserve. The sperm reserve of the left caput and caudal were however, higher (p>0.05) than those of the right. The mean epididymal sperm reserve for caput, corpus and caudal were 84.857×106, 268.71×106 and 542.79×106, respectively. It was concluded that testicular morphometric characteristics have the potential to be used in predicting sperm production capacity in live camels' bulls. Les éleveurs peuvent avoir besoin d'une gamme de référence de tailles testiculaires et de réserves de sperme pour vérifier l'efficacité reproductive d'un mâle. Cependant, l'information sur la morphométrie testiculaire de chameau et la réserve gonadale de sperme au Nigeria semi-aride est maigre. Cette étude a été conçue pour fournir des informations sur la morphométrie testiculaire et les réserves gonadales et extragonadales de spermatozoïdes de chameaux dans la région du Sahel au Nigeria. Des testicules de 15 chameaux matures et sains ont été obtenus auprès de l'abat de l'abattoir central de Maiduguri. La circonférence scrotale a été mesurée sur l'animal vivant jusqu'au centimètre le plus proche. Des poids de chaque testicule, épididyme et ses parties distinctes et tunicaalbuginae ont été obtenus au milligramme le plus proche. La longueur et la largeur de chaque testicule et la longueur des parties distinctes de l'épididyme ont été mesurées au millimètre près. Les réserves de sperme gonadal et extra-gonadal ont également été estimées. Toutes les données ont fait l'objet de statistiques descriptives, d'un t-test apparié et d'une analyse de corrélation. La circonférencescrotale s'est étendue de 24.00 à 49.00cm avec une moyenne de 38.59 ± 2.41cm. On a observé une relation significative élevée (r = 0,69) entre la circonférence scrotale et le poids apparié des testicules. Les testicules gauche et droit ont eu la réserve semblable de sperme. La réserve de sperme du caput gauche et du caudal étaient toutefois plus élevées (p>0,05) que celles de la droite. La réserve épididymale moyenne de sperme pour le caput, le corpus et le caudal étaient 84.857×106, 268.71×106 et 542.79×106, respectivement. Il a été conclu que les caractéristiques morphométriques testiculaires ont le potentiel d'être utilisées pour prédire la capacité de production de sperme chez les taureaux de chameaux vivants.
