Summary
Post-mating uterine inflammation in horses, pigs, and cattle is a natural defense mechanism. Seminal components and sperm influence this response, which is crucial for fertility and pregnancy success.
Area of Science:
- Reproductive Immunology
- Veterinary Science
- Comparative Mammalian Reproduction
Background:
- Post-mating endometritis is a significant cause of infertility in horses.
- Uterine inflammatory responses to mating occur in pigs and cattle but are less studied.
- Understanding these responses is key to improving reproductive efficiency in livestock.
Purpose of the Study:
- To review current knowledge on uterine inflammatory responses after mating in horses, pigs, and cattle.
- To highlight the roles of spermatozoa and seminal plasma in inducing inflammation.
- To compare inflammatory mechanisms across these species.
Main Methods:
- Literature review focusing on equine, porcine, and bovine reproductive immunology.
- Analysis of factors influencing post-mating uterine inflammation, including semen characteristics and deposition site.
- Examination of cellular and molecular mediators of the inflammatory response.
Main Results:
- Spermatozoa, seminal plasma, and semen extenders initiate uterine inflammation.
- Inflammation involves cytokines, polymorphonuclear leucocytes (PMN), and mononuclear cells.
- Seminal plasma induces transient immune tolerance and regulates ovarian function, impacting fertility.
Conclusions:
- Post-mating uterine inflammation is a critical defense mechanism that eliminates excess sperm and microbes.
- Effective resolution of inflammation and tissue repair are essential for successful pregnancy.
- Seminal plasma plays a complex role in modulating the immune response and supporting reproductive success.

01:20Proliferative Phase
The proliferative phase typically occurs after menstruation and lasts between 6 to 13 days in a standard 28-day cycle. This phase involves the reconstruction of the endometrium, guided by estrogen produced by the developing ovarian follicle.
Notably, the stratum basale, the basal layer of the endometrium, including the basal parts of the uterine glands, remains unaffected by menstruation. Stem cells in this layer undergo mitosis, regenerating the stratum functionalis and thickening the...

01:19Secretory Phase
The secretory phase of the menstrual cycle, spanning from day 14 to 28 in a typical 28-day cycle, is a period of significant physiological changes in the female reproductive system. This phase commences immediately after ovulation and is characterized by the preparation of the endometrium for potential embryo implantation.
Following ovulation, the corpus luteum, a temporary endocrine structure, produces progesterone and estrogens. These hormones stimulate the growth and coiling of endometrial...

01:26Acute Inflammation I: Inflammatory Response
Acute inflammation is a rapid, short-lived physiological response to tissue injury or infection, designed to eliminate harmful agents and initiate repair. This tightly regulated process typically lasts from minutes to several days and is triggered by factors such as microbial invasion, physical trauma, or chemical injury.Recognition and Mediator ReleaseThe inflammatory response begins when resident immune cells—such as mast cells, macrophages, and dendritic cells—detect damage-associated...
01:27Ovarian Cycle
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle length...
01:18Menses Phase
The uterine cycle begins with the menstrual phase, which is considered day one of the cycle and typically lasts about five days. This phase is characterized by the degeneration and shedding of the stratum functionalis, the functional layer of the endometrium.
When fertilization does not occur, the corpus luteum deteriorates, causing a significant drop in the levels of estrogen and progesterone in the body. This hormonal decrease triggers the release of prostaglandins, which cause the uterine...

01:28Inflammatory Response
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...
