Heparin and Progesterone Exert Synergistic Effects to Improve the In-Vitro Fertilization Rate of Bovine Sperm Bound to Oviduct Cell Aggregates from the Isthmus. Vet Sci 2022; 9:vetsci9070372. [PMID: 35878389 PMCID: PMC9318521 DOI: 10.3390/vetsci9070372] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2022] [Revised: 07/08/2022] [Accepted: 07/14/2022] [Indexed: 12/02/2022] Open
Abstract
Simple Summary After mating, sperm starts its long journey with the ultimate goal of fertilizing the oocyte. Inside the oviduct, sperm is attached to the surface of epithelial cells. The intact and good-quality sperm are elected and stored. Many infertility-related problems are related to the short life span of the sperm and/or the delay of the capacitation process of sperm attached to the oviduct. Thus, the elongation of the life span of the sperm would be very helpful in overcoming such problems. We hereby aimed to evaluate the fertilization ability of sperm that bind to cell aggregates oviduct (infundibulum-ampulla-isthmus), and assess the effect of heparin and or progesterone on the in-vitro fertilization ability of sperm co-incubated with isthmus cells aggregates. The sperm bound to isthmus aggregates improved the rate of in-vitro fertilization compared to infundibulum and ampulla. Moreover, pre-treatment of mature oocytes with heparin and progesterone plays a coactive role that improves the in-vitro fertilization of sperm bound to cell aggregates from isthmus. In conclusion, binding to isthmus aggregates improves the in-vitro fertilization of bovine sperm. Additionally, heparin together with progesterone, exerts a synergistic action that improves the in-vitro fertilizing potential of sperm attached to isthmus aggregates. Abstract After the copulation process, some sperm start the long journey with an ultimate goal of fertilizing the oocyte. Inside the oviduct, sperm are stored, waiting for the ovulated oocyte where they bind to the apical surface of the oviduct cells, which in turn hold sperm to form a sperm nest. The essential functions of the sperm reservoir include attaching spermatozoa to oviduct epithelial cells, selecting intact, good-quality sperm with an end result of extending sperm life expectancy. The current study aimed to evaluate the fertilization ability of sperm that bind to cell aggregates from different parts of the oviduct (infundibulum-ampulla-isthmus), and to assess the effect of heparin and or progesterone (P4) on the in-vitro fertilization ability of sperm co-incubated with cell aggregates from the isthmus. In-vitro fertilization was identified as a cleaved oocyte to two cells or more. The sperm bound to cell aggregates from the isthmus improved the rate of in-vitro fertilization (48.09%) compared to aggregates from the infundibulum (36.90%) and ampulla (37.61%). Moreover, pre-treatment of mature COCs with heparin (40 μg/mL) and P4 (80 nanomolar) play a coactive role that improves the in-vitro fertilization ability of sperm bound to cell aggregates from isthmus (63.33%), compared to 42.61% in the absence of cells aggregates. In conclusion, binding to cell aggregates from isthmus improves the in-vitro fertilization ability of Bovine sperm. Additionally, heparin, together with P4, exerts a synergistic action that improves the in-vitro fertilizing potential of sperm attached to cell aggregates from the isthmus of the bovine oviduct.

Relationship between concentrations of macro and trace elements in serum and follicular, oviductal, and uterine fluids of the dromedary camel (Camelus dromedarius). Trop Anim Health Prod 2019; 52:1315-1324.

Abstract
This study aimed at investigating the relationship between concentrations of macro and trace elements in blood serum, and fluids from small and large follicles (SFF and LFF, respectively), oviduct (OF), and uterus (UF) of female dromedary camels. Fluids from small (2-6 mm) and large follicles (7-20 mm), oviduct and uterus, and blood samples were collected from 19 camels. The results indicated that the concentrations of serum Mg, Fe, and Mn were significantly higher than their follicular fluid, OF, and UF concentrations. Levels of Zn, Fe, Cu, Cr, and Mn were significantly higher in SFF than in LFF. Se and Mo concentrations were higher in LFF. Co concentration was lower in serum than in reproductive tract fluids. Cr concentration was higher in UF and OF than in the serum, SFF, and LFF. High Ca concentration was observed for serum and SFF, followed by LFF. The concentration of Na was about 1.18-fold higher in SFF than in serum, OF, and LFF, and approximately 4.1-fold higher in serum than in UF. K was present in higher concentration in SFF than in serum and LFF; however, its concentration was low in UF and OF. In conclusion, this study shows the concentrations of certain elements in small and large follicular, uterine, and oviductal fluids, which may be low or high depending on their function in the development and growth of follicles. This information can support the development of new media for in vitro oocyte maturation and fertilization of female camels.

Abstract
In the bovine up to 40% of embryos die before implantation but despite the importance of ions in oviduct and uterine fluid formation and in gamete, zygote and early embryo development there is very little published information on the ion concentrations of oviduct or uterine fluid. The free anions chloride, phosphate and sulphate and the free cations sodium, calcium, magnesium and potassium were measured in oviduct fluid on days 0, 2, 4 and 6 and in uterine fluid on days 6, 8 and 14 and in corresponding blood samples. Oviduct and uterine fluids were collected in situ. Sodium was 25-fold higher than potassium and 80-fold higher than the other ions and chloride was 10-fold higher than potassium and 40-fold higher than the other ions in oviduct and uterine fluid. Phosphate, sulphate, magnesium, potassium and calcium were at lower concentrations in all fluids. Oviduct calcium and sodium were higher on day 0 than other days. The most striking uterine differences were the higher potassium and lower chloride, sodium and magnesium on day 14 than other days. There were significant positive associations between oviduct and blood chloride, sulphate, magnesium and calcium while only uterine sulphate was positively related to its blood concentration. There was no relationship between fluid secretion rate and no association between the concentrations of systemic progesterone or oestradiol and any ion in oviduct or uterine fluid. The different concentrations and associations between ions in the oviduct, uterus and blood suggest a differential regulation of ion secretion by the oviduct and uterine epithelia.

Abstract
A study was undertaken to determine the effects of oviductal proteins obtained from various stages of the estrous cycle on spermatozoa characteristics in buffaloes. Oviducts were collected from apparently healthy buffalo genital tracts (nonluteal and luteal stage of estrous cycle) and separated into isthmus and ampulla. Each segment of oviduct (nonluteal and luteal) was flushed with PBS (pH 7.4). The flushing obtained was centrifuged (3000 rpm; 30 min), filtered (0.2 microm) and frozen at -20 degrees C. The proteins in pooled nonluteal isthmic and ampullary and luteal isthmic and ampullary fluids were precipitated overnight using ammonium sulphate, centrifuged (10000 rpm; 30 min) and dialyzed (>10 kDa). After protein estimation, aliquots of samples containing 10 mg proteins were lyophilized in cryovials and stored in frozen form at -20 degrees C. Six pooled good-quality ejaculates collected by artificial vagina method from two Murrah buffalo bulls were utilized for the study. After fresh semen analysis, each pooled ejaculate was splited into five parts and extended in Tris-egg yolk-citrate extender (20% egg yolk; 7% glycerol), so that final dilution yielded approximately 60 million sperm cells per ml, and cryopreserved in 0.5 ml French straws (30 million sperm cells/straw) in LN(2) (-196 degrees C). Before freezing, nonluteal isthmic and ampullary and luteal isthmic and ampullary proteins were incorporated at the rate of 1mg/ml of extended semen. The equilibrated and frozen-thawed (37 degrees C for 30 s) semen was evaluated for motility, live %, acrosomal integrity percentage, bovine cervical mucus penetration test and hypo-osmotic sperm swelling test. Besides this, spermatozoa from treatment and control groups were incubated at 37 degrees C for 6 h in sperm TALP. Among the nonluteal and luteal oviductal proteins, the former maintained higher (P < 0.05) post-thaw sperm motility, live %, and acrosomal integrity than the control group. Between the isthmic and ampullary proteins, the isthmic proteins incorporated group maintained higher (P < 0.05) post-thaw sperm motility, live %, and acrosomal integrity. Similarly, higher sperm penetration distance in cervical mucus was recorded in nonluteal isthmic proteins incorporated group. But, irrespective of the stage of an estrous cycle, isthmic proteins included group maintains higher sperm membrane integrity as revealed by higher (P < 0.05) swollen sperm percentage in response to hypo-osmotic solution than the ampullary proteins included and control groups. Similarly, at any time during incubation the sperm motility and viability was higher (P < 0.05) in isthmic proteins treated group than the ampullary and control group. But, the same trend was not observed in terms of acrosomal integrity percentages. It is inferred that inclusion of oviductal proteins in the extender prior to freezing improved post-thaw semen quality. Oviductal proteins differentially affected sperm function depending upon the region of oviduct and the stage of estrous cycle at which the proteins were obtained.

Abstract
High dietary protein leads to elevated systemic concentrations of ammonia and urea, and these, in turn, have been associated with reduced fertility in cattle. The effect of elevating systemic concentrations of ammonia and urea on the concentrations of electrolytes and nonelectrolytes in bovine oviductal fluid were studied using estrus-synchronized, nulliparous heifers (n = 25). Heifers were randomly assigned to 1 of 3 treatments consisting of jugular vein infusion with either ammonium chloride (n = 8), urea (n = 8), or saline (n = 9). Oviducts were catheterized, and fluid was recovered over a 3-h period on either Day 2 or 8 of the estrous cycle. No difference (P > 0.05) was found in the concentrations of any electrolyte or nonelectrolyte between oviducts ipsi- or contralateral to the corpus luteum. Plasma and oviductal concentrations of urea were increased by infusion with urea (P < 0.001) and ammonium chloride (P < 0.05) but not by saline (P > 0.05). Plasma and oviductal concentrations of ammonia were elevated by infusion with ammonium chloride (P < 0.001) but not by infusion with urea or saline (P > 0.05). No effect (P > 0.05) of treatment was found on oviductal or plasma concentrations of glucose, lactate, magnesium, potassium, or sodium or on plasma concentrations of insulin or progesterone. The concentration of calcium in oviductal fluid was reduced by urea infusion and was negatively associated with systemic and oviductal concentrations of urea. Oviductal concentrations of sodium were higher on Day 8 than on Day 2 (P < 0.05). No effect of sample day was found on any of the other electrolytes or nonelectrolytes measured (P > 0.05). Elevated systemic concentrations of ammonia and urea are unlikely to reduce embryo survival through disruptions in the oviductal environment.

Abstract
L-HGP is a highly glycosylated protein from Bufo arenarum egg-jelly coat that diffuses into the surrounding medium when the strings of oocytes are incubated in saline solutions. L-HGP was purified from egg water and the estimated percentage of L-HGP/total protein in egg water was estimated in 30%. In the present study we examine, by indirect immunofluorescence, the effect of L-HGP on acrosome status of homologous spermatozoa. A high percentage (77%) of sperm lost the acrosome when incubated in 10% Ringer solution buffered with 10 mM Tris-HCl, pH 7.6, during 60 min, a condition that resembles egg-jelly osmolarity. The addition of purified L-HGP to the incubation medium prevents acrosome breakdown. The acrosome integrity is maintained for at least 1 hr. This effect is specific for L-HGP at concentration ranging from 0.01 to 0.1 mg/ml since neither BSA nor fetuin seems to have similar activity at similar concentrations. The same effect was observed when spermatozoa were incubated in egg water. Preliminary results suggest that L-HGP binds to B. arenarum spermatozoan membranes.

Abstract
A bovine oviductal fluid catalase (OFC) which preferentially binds to the acrosome surface of some mammalian spermatozoa has recently been purified. The objectives of this study were to clone the OFC, obtain the full-length cDNA and protein sequence and determine which characteristics of the proteins are associated with the binding of the enzyme to sperm surface. Northern blot analysis revealed low levels of catalase mRNA in bovine oviducts and uterus compared to the liver and kidney. Screening of a cDNA library from the cow oviduct permit to obtain a full-length cDNA of 2282 bp, with an open reading frame of 1581 bp coding for a deduced protein of 526 amino acids (59,789 Da). The deduced protein contained four potential N-glycosylation sites and many potential O-glycosylation sites. The OFC protein exhibited high identity with catalase from other bovine tissues, likewise with catalases from human fibroblast and kidney, and with rat liver catalase. The homology of amino acid sequence of OFC with bovine liver catalase was about 99%. However the OFC possess an extended carboxyl terminus of 20 amino acids not present on the liver catalase. This result is supported by a lower mobility of the OFC compared to the liver catalase when both proteins are submitted on SDS-PAGE.

Abstract
Oviduct fluid and oviduct epithelium seem able to modulate in-time maturation and transport of gametes and embryos. They probably allow selection of spermatozoa through too early activation. Subtle changes in the composition of tubal secretion permit fertilization and embryo development in the best conditions. The mechanisms of these changes of oviduct fluid composition (induced by endocrine stimuli and/or by embryo) are under investigation. Numerous compounds isolated in oviduct fluid are now added to the synthetic media for in vitro maturation/in vitro fertilization/embryo culture (IVM/IVF/EC). The rationale is now to mimic more and more, the biochemical composition of tubal and uterine fluids even if interactions with embryo metabolism is still far from being understood.

Abstract
Because the different portions of the female genital tract act in many ways on sperm metabolism, the current study was undertaken to modulate the survival and fertilizing ability of bovine semen by incorporation of products from the oviduct or the follicle in extenders before freezing. Motility rates at 6 h in vitro showed a net positive effect when biological factors from total retentate or from a fraction of bovine follicular fluid (total retentate = 43%; fraction 2 = 54%), oviductal cell culture (total retentate = 43%; fraction 2 = 58%), or granulosa cell culture (total retentate = 43%; fraction 3 = 53%) were added to the extenders compared with the addition of BSA (31%). Fraction 3 of granulosa cell culture retentate also had a significant stimulatory effect on the number of sperm that penetrated mucus of cows in estrous compared with BSA (n = 205 vs. n = 159). The intracellular sperm Ca2+ concentrations were very different across treatments after thawing. Sperm from straws with BSA had the highest concentration. At 4 h, intracellular Ca2+ concentration increased for all treatments, except that for sperm treated with BSA and Ca alone, internal Ca2+ declined. Heparin plus Ca stimulated a greater internalization of Ca2+ than did Ca alone for retentate from bovine follicular fluid, oviductal cell culture, and BSA treatments: glucose consistently and significantly reduced internalization. In vitro fertilization rates were similar, and no significant differences were observed across treatments.
