Spanner EA, de Graaf SP, Rickard JP. Uterine tone influences fertility of Merino ewes following laparoscopic artificial insemination. Theriogenology 2024; 222:45-53. [PMID: 38615435 DOI: 10.1016/j.theriogenology.2024.04.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2024] [Revised: 04/01/2024] [Accepted: 04/01/2024] [Indexed: 04/16/2024]
Abstract
Artificial insemination (AI) plays a critical role in facilitating rapid genetic and production gains within the sheep industry. However, variable rates of AI success remain a concern for the industry and a barrier to adoption. Furthermore, the degree to which female factors influence the success of intrauterine laparoscopic AI rather than natural mating remains unknown. As such, this study investigates the effect of several factors collected during the time of AI, on the success of intrauterine laparoscopic AI. Data was generously donated by artificial breeding companies and stud breeders during routine commercial AI operations. AI data was collected over 3 breeding seasons during commercial AI programs (N = 24 programs) using Merino ewes (N = 24,700). Sire ID (N = 253), time of AI following progesterone removal (approx. 43-59 h post removal), uterine tone and intra-abdominal fat (both scored 1-5) as well as age of the ewe were all recorded at the time of AI. Transcutaneous ultrasound subsequently determined pregnancy rate approximately 55 days post-AI. A multivariate regression analysis was performed and revealed pregnancy success to increase when semen was inseminated into a ewe with a uterine tone score of 4 or 5 (P < 0.001). The remaining factors fell short of significance within the multivariate model. An interclass coefficient variation matrix was also used to determine the proportion of variation contributed to AI success by random factors allocated in the model; site, sire, AI date and breeding season (45.99 %, 29.94 %, 15.15 % and 8.92 %, respectively). These results highlight the influence of uterine tone on ewe fertility following laparoscopic AI, but also that program location and the sire used can further modify this influence on pregnancy rate. These factors must now be considered in combination with semen factors per individual sire used during AI to ascertain the contribution of several factors to the success of laparoscopic AI in Australia.

Protective effect of Petroselinum crispum methanolic extract against acrylamide-induced reproductive toxicity in male rats through NF-ĸB, kinesin, steroidogenesis pathways. Reprod Toxicol 2024; 126:108586. [PMID: 38614435 DOI: 10.1016/j.reprotox.2024.108586] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2024] [Revised: 03/19/2024] [Accepted: 03/29/2024] [Indexed: 04/15/2024]
Abstract
This study examined the protective effects of a Petroselinum crispum (P. crispum) methanolic extract on reproductive dysfunction induced by acrylamide in male rats. A total of 40 rats were divided into four groups (n=10). The control group received distilled water, the acrylamide group received 10 mg/kg of acrylamide, the P. crispum group received 100 mg/kg of P. crispum extract, and the combined group was pretreated with P. crispum for two weeks before co-administration of P. crispum and acrylamide. All administrations were administered orally using a gastric tube for eight weeks. Acrylamide decreased testosterone levels but did not affect levels of FSH or LH. It also increased testicular levels of (MDA) malondialdehyde and reduced activity of (SOD) superoxide dismutase and impairment of sperm parameters. Furthermore, the administration of acrylamide resulted in an elevation of tumor necrosis factor-alpha (TNF-α) levels and a reduction in the levels of steroidogenic acute regulatory protein (STAR) and cytochrome P450scc (P450scc). Acrylamide negatively affected the histopathological outcomes, Johnsen's score, the diameter of seminiferous tubules, and the thickness of the germinal epithelium. It also upregulated the expression of NF-ĸB P65 and downregulated the expression of kinesin motor protein. In contrast, treatment with P. crispum extract restored the levels of antioxidant enzymes, improved sperm parameters, and normalized the gene expression of TNF-α, IL-10, IL-6, iNOS, NF-ĸB, STAR, CYP17A1, 17β-HSD and P450scc. It also recovered testicular histological parameters and immunoexpression of NF-ĸB P65 and kinesin altered by acrylamide. P. crispum showed protective effects against acrylamide-induced reproductive toxicity by suppressing oxidative damage and inflammatory pathways.

Abstract
Successful artificial breeding underpins rapid genetic and production gains in animal agriculture. In sheep, artificial insemination with frozen semen is performed via intrauterine laparoscopy as frozen-thawed spermatozoa do not traverse the cervix in sufficient numbers for high fertility and transcervical insemination is anatomically impossible in most ewes. Historically, laparoscopic artificial insemination has always been considered reasonably successful, but recent anecdotal reports of poor fertility place it at risk of warning adoption. Understanding the male, female and environmental factors that influence the fertility of sheep is warranted if the success of artificial insemination is to be improved and genetic progress maximised for the sheep industry. This review details the current practice of laparoscopic AI in sheep. It explores the effects of semen quantity and quality, the ewe, her preparation, and environmental conditions, on the fertility obtained following laparoscopic artificial insemination.

The interaction between seminal plasma biochemical constituents and short-term semen preservation in Honamli and hair goats. Reprod Domest Anim 2023; 58:387-395. [PMID: 36447389 DOI: 10.1111/rda.14297] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2022] [Revised: 11/07/2022] [Accepted: 11/23/2022] [Indexed: 12/05/2022]
Abstract
This study investigated the short-term storage of Honamli and Hair buck semen based on the relationships among the biochemical constituents of the seminal plasma. In total, 12 Honamli and Hair goat bucks (six of each breed) were used. Collected individual semen samples were divided into two parts, one placed in short-term storage and the other centrifuged to determine the biochemical constituents of the seminal plasma. Diluted semen samples were cooled to +4°C; the samples were stored at this temperature; the spermatological parameters (i.e., motility, plasma membrane and acrosome integrity [PMAI], viability and high mitochondrial membrane potential) were assessed at 0, 24, 48, 72 and 144 h. A significant positive correlation was determined between the PMAI, motility and viability with globulin, chlorine, alanine aminotransferase (AST) and aspartate aminotransferase (ALT). A positive correlation was detected between the PMAI and viability with total protein. In contrast, a negative correlation was determined between the motility and viability with sodium values in buck semen (p ˂ .05). Also, it was evaluated the Hair buck samples became inviable across all parameters at 72 h, while the Honamli buck samples continued to be viable at 144 h. In conclusion, the seminal plasma biochemical parameters of total protein chlorine, globulin, albumin, sodium, AST and ALT correlated with spermatological parameters in buck semen. The factors of animal (p ˂ .05) and time (p ˂ .001) affected the spermatological parameters, but there was no interaction between the two factors (p > .05) during the short-term storage period. Also, it was determined that Honamli buck semen was more resistant to cold injury than Hair buck semen against cold injury during storage.
