State-of-the-art of boar sperm preservation in liquid and frozen state. A total of 36 ejaculates (one per boar) collected from boars of different ages (from 9 to 35 months) of the same mentioned above breeds were used. Reproduction. 2020;9:113. The SP concentration of OXT did not differ among breeds (inter-breed variability), the four breeds showing similar concentrations (median, 2575th percentiles; Pietrain: 14.23, 9.9145.95ng/mL; Duroc: 18.43, 6.7837.86ng/mL; Landrace: 11.70, 9.3616.13ng/mL; Large White: 20.99, 16.8225.09ng/mL; Fig. Oxytocin has a plasma half-life of about 1 to 6 minutes which is decreased in late pregnancy and during lactation.

Direct competitive immunoassay test based on AlphaLISA used for oxytocin assessment in pig seminal plasma samples. I mean, don't trust me. According to the Centers for Disease Control and Prevention, approximately 23% of deliveries in the United States are induced. This increase in litter size was not found in the present study, perhaps because the SP-OXT concentrations measured in the present study were significantly lower than those used in the aforementioned studies, which ranged from 0.04 to 0.1IU/mL. [47] in pigs, which showed that OXT is particularly active in the accessory glands, more specifically in the prostate. Mostafa T, Rashed LA, Osman I, Marawan M. Seminal plasma oxytocin and oxidative stress levels in infertile men with varicocele. Thereafter, 10L of biotinylated OXT-BSA (1 nmol/L, Cusabio Technology LLC, Houston, TX, USA) was added to each well and the plates incubated again at RT for 60min. Also, severe meconium staining was higher in live born and still born pigs born in oxytocin treated litters. Labor induction versus expectant management for low-risk nulliparous women. https://doi.org/10.1016/j.theriogenology.2015.07.009. Ejaculates of boars showing positive farrowing rate deviation exhibited higher (P<0.05) SP-OXT concentration/mL than those with negative farrowing rate deviation. Journal of Animal Science and Biotechnology Your personal experience may also depend on your expectations,how you and your baby respond, and how your practitioner uses the medication. Exploring seminal plasma GSTM3 as a quality and in vivo fertility biomarker in pigsrelationship with sperm morphology. A comparison of methods to measure central and peripheral oxytocin concentrations in human and non-human primates. The harvested SP was microscopically examined (Eclipse E400; Nikon, Tokyo, Japan) to check for sperm presence. Anim Sci J. Vet Q. Whether your birth experience goes according to plan or not, it is helpful to have adequate support, such as a partner, family, or doula. Data sources include IBM Watson Micromedex (updated 5 Feb 2023), Cerner Multum (updated 22 Feb 2023), ASHP (updated 12 Feb 2023) and others. Cyclopropane anesthesia may modify oxytocin's cardiovascular effects, so as to produce unexpected results such as hypotension. a-b indicates significant differences (P<0.05) between groups of boars in the SP concentration of OXT. Lpez-Arjona M, Mateo SV, Escribano D, Tecles F, Cern JJ, Martnez-Subiela S. Domest Anim Endocrinol. 2003;81(4):8219. Pea FJ, Domnguez JC, Carbajo M, Anel L, Alegre B. The percentage of spermatozoa with intact plasma and acrosome membranes (H-42+/PI/PNA-FITC-) were recorded as viable sperm. Unlike the Mostaf study [27], the boars included in our study were all fertile, to a greater or lesser extent, but fertile. There are several methods to encourage labor, but in medical settings, one of the most commonly used is the drug Pitocin. Drugs.com provides accurate and independent information on more than 24,000 prescription drugs, over-the-counter medicines and natural products. Store between 20 to 25C (68 to 77F). However, the physician should be aware of the fact that oxytocin even in its pure form has inherent pressor and antidiuretic properties which may become manifest when large doses are administered. Barranco I, Padilla L, Perez-Patino C, Vazquez JM, Martinez EA, Rodriguez-Martinez H, et al. (See USP Controlled Room Temperature. Unless otherwise specified, reagents and equipment for OXT measurements were from PerkinElmer (Waltham, MA, USA) and fluorochromes for sperm analyses from Thermo Fisher Scientific (Waltham, MA, USA). It is standardized to contain 10 units of oxytocic hormone/mL and contains 0.5% Chlorobutanol, a chloroform derivative as a preservative, 1.65 mg acetic acid and 0.16 mg ammonium acetate as buffers, and with the pH adjusted with acetic acid to achieve a targeted pH of 3.5. doi:10.1590/1518-8345.0765.2744. Specifically, in pigs has been identified OXTR in the epididymis and testis [20]. These differences could explain the disagreement between the results of Mostaf and ours. I mean, don't trust me. The percentage of viable spermatozoa exhibiting high plasma membrane fluidity (H-42+/ Yo-Pro-1/M-540+) was recorded. Sperm motility was evaluated using a computer assisted sperm analyzer (CASA, ISASV1, Proiser R+D S.L., Paterna, Spain).

Relationship between the concentration of oxytocin in seminal plasma (SP-OXT) and in vivo fertility outcomes of boars used in artificial insemination programs (n=18). ; Data curation: L.P. and M.L-A. Your doctor or midwife may put in place any of the following: As with any medication or intervention, using Pitocin has risks. In this regard, Okazaki et al. https://doi.org/10.1016/j.jprot.2013.05.029. The response to a given dose of oxytocin is very individualized and depends on the sensitivity of the uterus, which is determined by the oxytocin receptor concentration. All authors read and approved the final manuscript. It's even being tested as an anti-anxiety drug. Moreover, the presence of OXT in semen has also been documented in men [26, 27] and stallions [23] and a putative role of SP-OXT on both sperm functionality and female genital tract performance has been suggested [27]. The combined solution containing 10 milliunits (mU) of oxytocin/mL is rotated in the infusion bottle for thorough mixing. Then, greater contractility would result in a greater volume of the ejaculate. Moscovice LR, Gimsa U, Otten W, Eggert A. Regardless of your plans, labor and delivery rarely go exactly as expected. Oxytocin promotes contractions by increasing the intracellular Ca2+. Theriogenology. Synthetic, For Intravenous Infusion Moreover, the boars were also grouped into three further sub-groups according to deviations in total litter size: positive (from 0.22 to 0.83 piglets, n=6), without (from 0.15 to 0.11 piglets, n=8) and negative (from 0.22 to 0.42 piglets, n=4) deviation (Fig. Clipboard, Search History, and several other advanced features are temporarily unavailable. Reprod Domest Anim. The .gov means its official. 2015;47(2):20913. Pitocin may contain up to 16% of total impurities. Phosphate buffered saline (PBS; Merck KgaA, Darmstadt, Germany) was used to extend semen samples for flow cytometry analyses. Bugg GJ, Siddiqui F, Thornton JG. Nat Commun. In this matter, the role of SP-OXT could be to stimulate the secretion of prostaglandin E2 by the endometrium of sows [49], which has immunosuppressive activity and, therefore, contributes to creating a tolerogenic environment in the uterus [29]. When properly administered, oxytocin should stimulate uterine contractions comparable to those seen in normal labor. Epididymal oxytocin in the rat: its origin and regulation. Theriogenology. Noteworthy, the measured concentrations of OXT in single SP samples (one ejaculate per boar) varied between boars but not between breeds. Conceptualization: L.P., M.L-A., S.M-S, J.R. and I.B.

Similarly, a wide variability (P<0.001) in the SP concentrations OXT was found among ejaculates from a same boar (intra-boar variability). Therefore, it would be reasonable that the differences between boars in SP concentrations of OXT could be genetically determined. Hhn U, Fritzsch M, Dahms R. Control of fertility outcome in artificially inseminated gilts and old sows. The dosage of oxytocin is determined by the uterine response and must therefore be individualized and initiated at a very low level. Some of the above empirical studies found that the supplementation of AI-doses with OXT also improved litter size in addition to farrowing rates [31, 33, 34]. Semin Cell Dev Biol. 2023 BioMed Central Ltd unless otherwise stated. Also, every experience with Pitocin will be different. Perhaps seminal OXT may influence other sperm functions, such as sperm capacitation. Am J Primatol. 2020;9:114. CAS ** P<0.01, *P<0.05. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. volume12, Articlenumber:101 (2021) The following adverse reactions have been reported in the mother: Excessive dosage or hypersensitivity to the drug may result in uterine hypertonicity, spasm, tetanic contraction, or rupture of the uterus.

American College of Obstetricians and Gynecologists: ACOG Technical Bulletin Number 110November 1987: Induction and augmentation of labor. Following intramuscular injection of the drug, uterine response occurs within 3 to 5 minutes and persists for 2 to 3 hours. The boars were placed in individual pens in a building with controlled air temperature (1525C) and with 16h of continual light per day. This study characterized concentrations of SP-OXT in ejaculates from boars used in artificial insemination (AI) programs aiming to evaluate its relationship with sperm quality variables and in vivo fertility of their liquid-stored AI-semen. Oxytocin is a hormone produced in the hypothalamus and excreted by the pituitary gland. It is administered by an IV injection that helps start contractions or further them. Improper oxytocin use can also cause an increased number of stillbirths by causing ruptured umbilical cords that lead to decreased oxygen delivery to the piglet during birth. Additionally, people may choose to induce using Pitocin due to timing or other issues, such as working around schedules to ensure a partner (or a specific doctor) can be present at the delivery. Oxytocin augmentation of labour in women with epidural analgesia for reducing operative deliveries. The hormone also works on on a positive feedback loop.. Elabd C, Cousin W, Upadhyayula P, Chen RY, Chooljian MS, Li J, et al. Arch Androl. There are no known indications for use in the first trimester of pregnancy other than in relation to spontaneous or induced abortion. J Proteome Res. https://doi.org/10.1016/j.theriogenology.2019.05.030. The second experiment intended to find out if SP-OXT concentrations were related to the age of boars and ejaculate characteristics and if they influenced sperm parameters from diluted semen samples stored at liquid state, such as those used in AI programs. As a medication, it is used to cause contraction of the uterus to start labor, increase the speed of labor, and to stop bleeding following delivery. From each ejaculate, a semen sample of 5mL was centrifugated twice at room temperature at change to: 1,500 g for 10min (RT, Rotofix 32A, Hettich Centrifuge UK, Newport Pagnell, Buckinghamshire, England, UK). The control sows were allowed to farrow without intervention. However, we do not believe that this is the case in our study. The 18-AI boars included in this sub-study were those of Landrace and Large White breeds, whose semen was collected (four ejaculates per boar) over a 12-month period (one SP sample per boar every four mos.) Violin plots displaying oxytocin (ng/mL) concentration levels and its distribution in seminal plasma (SP-OXT) of entire ejaculates (n=72) from 18 artificial insemination boars (four ejaculates per boar). Meconium staining is a good indicator that the piglets are oxygen deprived. This is done in the following way. Specifically, more than 200106 sperm/mL, 70% motile sperm and 75% sperm with normal morphology. Would you like email updates of new search results? Lpez-Arjona M, Escribano D, Mateo SV, Contreras-Aguilar MD, Rubio CP, Tecles F, Cern JJ, Martnez-Subiela S. Res Vet Sci. Sperm morphology was microscopically (Eclipse E400, Nikon, Tokyo, Japan) assessed in fixed sperm samples (1:1, v/v, in 0.12% formaldehyde saline solution; Panreac, Barcelona, Spain) by counting a total of 200 sperm per sample. Boars of the same breed are genetically very similar, at least those used in our study. and transmitted securely. To evaluate the variability among boars (inter-boar variability) and among the ejaculates from the same boar (intra-boar variability), SP samples from ejaculates (four samples collected from four ejaculates per boar) of 18 boars from Large White (n=5) and Landrace (n=13) breeds were analyzed. Each dot indicates SP-OXT concentration of each individual ejaculate, dashed lines the median and dotted lines the 25th and 75th percentiles. However, administering oxytocin before the cervix is fully dilated or the first pig is born can lead to dystocia or difficult birth. Deviations are with respect to the breed means represented by the value 0 on the X-axis. 2016;86(1):18793. Am J Obstet Gynecol 1984; 150:225228. Hum Reprod Update. These differences were expected considering (1) variations in OXT concentrations have been reported when different OXT quantification methods are used [38], circumstance occurring among the three studies mentioned above, including the present report and (2) that differences between species in other SP components (proteins) had been previously reported and could due to species-related differences in mating strategy (vaginal vs uterine) [39]. It is naturally produced by the body in a brain region known as the hypothalamus and secreted by the pituitary gland. The following adverse reactions have been reported in the fetus or neonate: Premature ventricular contractions and other arrhythmias. 2015;50:1039. Although improper use of oxytocin has potentially negative implications, it also can be beneficial to the farrowing process to stimulate uterine contractions and prevent stillbirths in older sows. Oxytocin is a hormone secreted by the posterior lobe of the pituitary gland, a pea-sized structure at the base of the brain. eCollection 2021. doi:10.1002/14651858.cd007123.pub2, Costley PL, East CE. Anim Reprod. 2014;81(6):7806. The protocol used in your case will depend on why you are being induced and other factors specific to your medical needs. Stillbirth numbers are typically higher in older parity sows and generally occur later in the birth order. Martnez-Pastor F, Mata-Campuzano M, Alvarez-Rodrguez M, Alvarez M, Anel L, de Paz P. Probes and techniques for sperm evaluation by flow cytometry. 2014;85(1):814. Disclose the causes of these individual variations is still challenging. Eur J Pharmacol. Moreover, variability among individuals in the SP-OXT has also been reported in humans [27]. Thackare H, Nicholson HD, Whittington K. Oxytocin--its role in male reproduction and new potential therapeutic uses. Oxytocin is frequently used to decrease farrowing time and birth interval as an aid to prevent stillbirths. Oxytocin (OXT), a small peptide hormone mainly synthetized in the magnocellular neurons of the hypothalamus, would be another SP component potentially Cookies policy. 2010;140(4):61322.

More research is required to elucidate this matter. The authors have declared no conflict of interest. During this 12-month period, the ejaculates of these boars were used to produce liquid-storage semen AI-doses (2,400106 of total spermatozoa in 80mL). Package insert / product label Theriogenology. A total of 101 litters were evaluated from the first farm and 373 litters were evaluated in the second trial. This fact must be considered by the physician in exercising his judgment regarding patient selection. Introduction Oxytocin is a hormone that is synthesized in the neurons of the brain and transported to the posterior pituitary. 1994;140(1):6372. Oxytocin is an age-specific circulating hormone that is necessary for muscle maintenance and regeneration. Porcine seminal protein-I and II mRNA expression in boar spermatozoa is significantly correlated with fertility. WebPitocin is a synthetic version of the naturally-produced hormone oxytocin. Its effect on length of insemination, pregnancy rate and litter size. To the very best of our knowledge, this is apparently the first study measuring the concentration of OXT in pig SP and the first report conducted in a livestock species assessing an eventual putative influence of SP-OXT concentrations on sperm reproductive performance post-AI. In this context, it has been reported that individual differences in OXT gene or OXTR led to a change in basal OXT concentrations in humans [43]. Article Front Behav Neurosci. https://doi.org/10.1111/and.12248. As far as we are aware of, no studies have been conducted in any livestock species evaluating the putative relationship between SP-OXT with sperm quality and function and in vivo fertility after AI. Seminal plasma proteins as potential markers of relative fertility in boars. Because of the variability of the combinations of factors which may be present in the conditions listed above, the definition of "unusual circumstances" must be left to the judgment of the physician.
