A high amount of blood and not the mere presence of blood in equine semen impacts fertility. The aim of this study was to develop an approach to rescue the fertility of stallions with high hemospermia levels. Semen from 15 stallions was divided into four experimental groups: (a) Control—pure raw semen, (b) WB50—50% (v/v) whole blood added into semen, (c) E1—WB50 extended in a 1:1 (v/v) ratio with milk‐based extender and (d) E2—WB50 extended in a 2:1 ratio with milk‐based extender. Sperm kinetics, plasma membrane integrity (PMI), lipid peroxidation (PER) and intracellular superoxide (O2) production were immediately evaluated. Four cycles of 20 mares were randomly assigned to the experimental groups. Mares were bred with an insemination dose of 1 billion total sperm and pregnancy was diagnosed 14 days after ovulation. Sperm kinetics could not be evaluated in the WB50 samples. Total motility was lower (p < .05) in E1 than in CT and E2 samples. Progressive motility decreased (p < .05) with an increase in the percentage of blood in the samples. The PMI and PER did not differ between groups (p > .05); however, O2 production was higher (p < .05) in WB50 than in E2 samples, while the values were intermediate (p > .05) for CT and E1 samples. The control (90%) and E2 (90%) groups had superior (p < .05) fertility than the others (WB50—0% and E1—25%). It was concluded that sperm motility and fertility of semen with a large amount of blood can be rescued by dilution with a 2:1 extender:semen ratio using a milk‐based extender.

“…These include intravenous administration of formaldehyde solution, oral administration of methenamine, systemic administration of antimicrobial drugs and more recently topical treatment with 4% Policresulen solution. [12][13][14] On the other hand, surgical treatment is aimed at decreasing pressure within the CSP to minimize or prevent hemorrhage through the rent so that it can heal. 1 The most common surgical approaches include PU and corpus spongiotomy (CS).…”

Recent advances on the uroliths manipulation and retrieval techniques have increased the success and significantly reduced complications and recurrence.…”

Perineal urethrostomy is a surgical technique performed for temporary or permanent urine diversion from the penile urethra in male patients with obstructive urinary outflow disease, extensive trauma or invasive tumor affecting penis and prepuce, to access the urethra or bladder to remove uroliths, and to treat horses affected with hemospermia or hematuria secondary to urethral rents. Perineal urethrostomy has been advocated as the treatment of choice in geldings where hematuria does not resolve with conservative treatment and in stallions with hemospermia caused by urethral defects. Most cases of geldings with hematuria are resolved with a single perineal urethrostomy surgery; however, stallions with hemospermia might need a second surgery. Perineal urethrostomy also enables access to the urinary bladder in male horses with cystoliths following minimal dissection and without accessing the abdominal cavity. The most common complications directly related to this surgery are hemorrhage, urine scalding, and urethral stricture at the surgical site. The aim of this article is to review comprehensively the indications for perineal urethrostomy surgery, illustrate the surgical technique approach, and discuss outcomes and complications.
