“…As previously reported, unilateral testis retention was more prevalent than bilateral presentation, and right-sided inguinal retention was also higher in frequency than left-sided retention in the evaluated horses (Hayes 1986, Straticò et al 2020. Abdominal cryptorchidism was more frequent on the right side (n=3) or bilateral (n=2), and just one animal was affected on the left testis in our survey, despite left abdominal retention being more frequent in horses (Snider 2015, Straticò et al 2020. As observed in both cases of bilateral cryptorchidism in equids, abdominal retention of the testis has been considered 2.5 times more common than the inguinal form (Straticò et al 2020).…”

“…Reproducing outstanding or high-genetic animals is among the most relevant businesses of equids husbandry in the horse industry. MRTDs may directly impact the reproduction performance of stallions, promoting significant economic losses (Snider 2015). In the present study, habronemiasis represented the major MRTD in equids referred for hospital care, affecting the glans penis and/or preputial skin fold.…”

“…Considering that horse herds include over 5.7 million animals in Brazil (IBGE 2021), affections of the male reproductive tract can cause a reduction in fertility and even disuse in the reproduction of stallions with high genetic and economic potential. Additionally, MRTDs may result in a significant economic impact on stud farms as well as on the entire horse industry (Snider 2015).…”

“…However, there are a few significant diagnostic issues in the scrotum and tunica vaginalis. Even though the exceeding majority of male horses are castrated during the young adult years, neoplasms affecting the male reproductive tract of geldings have been frequently observed (Foster & Laads 2015, Snider 2015. In this context, a proper clinical and pathological evaluation of genital lesions in male horses is essential for the correct diagnosis and proper treatment (Veado et al 2021).…”

Male reproductive tract disorders (MRTDs) are common in equids and may represent a significant proportion of the caseload of equine practitioners. Herein, we determined the frequency, clinico-pathological findings, and therapeutics of MRTDs in equids from a 9-year survey of the clinical records of a Veterinary Teaching Hospital in Midwestern Brazil. During this period, 87 affected equids presented 100 MRTDs distributed in 17 different diagnoses. Forty-three (49.4%) equids presented MRTDs affecting the glans penis or preputial skin fold. Testicles, scrotum, and spermatic cords disorders were diagnosed in 32 (36.8%) horses. Of the remaining 12 (13.8%) horses, six presented two different MRTDs on two distinct anatomical areas, and five animals exhibited the same disease, affecting two different anatomical locations. Only one horse presented three distinct MRTDs on two anatomical regions. Habronemiasis was the most frequent MRTD detected in 26% of the diagnoses, followed by miscellaneous wounds (14%), cryptorchidism (13%), inguinal hernia (13%), funiculitis (9%), paraphimosis (6%), squamous cell carcinoma (5%), urethrolithiasis (3%), preputial abscesses, and orchitis (2% each). Phimosis, ulcerative posthitis, epididymitis, hydrocele, papillomatosis, teratoma, and testicular torsion accounted for 1% each. Sixty-three (72.5%) equids received hospital discharge, 18 (20.6%) were humanely euthanized, and six (6.9%) died. This study detected the most relevant MRTDs that affected over 7.5% in a survey of 1,154 equids referred for hospital care. Our finding highlights that MRTDs may be debilitating and life-threatening conditions, and they can potentially impact the reproduction of equids in the region. This knowledge may support equine practitioners in elaborating proper sanitary and management protocols to prevent and reduce the incidence of most MRTDs recorded, improving equid production and welfare.

“…If a stallion passes on a venereal illness, he might be the causative factor of embryonic loss. Furthermore, studies have shown that when females are mated to sub fertile males, the likelihood of pregnancy loss increases ( Snider, 2015 ) (Very little data).…”

Early embryonic death in Equines and Camelids

This paper includes the study about early embryonic death, predisposing factors of early embryonic death and treatment. Early embryonic death refers to the fetal mortality which varies in mare and camelids but most probably not later than 50 days of gestation. This duration may be divided into very early mortality, early mortality, and late embryonic mortality. This also varies in mare and camelids. There are different embryonic, maternal, environmental/external, infectious, and noninfectious factors which lead to early embryonic loss. Diagnosis is very difficult as in most of the cases resorption of fetus occurs, but it is done using ultrasound machine. Unfortunately, there is no treatment to avoid early embryonic mortality. However, new reproductive technologies have increased the service rate in a herd, and efforts are still being made to determine the rate and frequency of camel embryonic loss.
