Abstract
BACKGROUND Anti-Müllerian Hormone (AMH) serves as a crucial parameter in assessing the reproductive herd life and ovarian reserve in cattle. Consequently, extensive research is conducted on AMH levels. Various measurement methods can be employed to determine AMH levels. However, to our knowledge, no study has been conducted on Holstein donors using the Elecsys® AMH kit. OBJECTIVE This study was designed to determine AMH levels in donors utilising the Elecsys® AMH kit and to evaluate the relationship between superovulation response parameters and AMH levels. METHODS In this study, we measured the serum AMH levels of 36 cows using the Elecsys® AMH automated assay before the superovulation protocol (1st sample) and FSH injections (2nd sample). The cows were categorised into three groups based on their AMH levels: low, medium, and high AMH. RESULTS Positive correlations were identified between AMH and parameters associated with superovulation response. The high AMH level group exhibited significantly greater numbers of corpus luteum, total embryos, transferable embryos, and grade 1 embryos compared to the medium and low AMH groups (p < 0.05) There was no significant difference between AMH levels before the superovulation protocol and FSH injections(p > 0.05). Body condition score and parity did not significantly affect AMH levels in cows (p > 0.05). Also, AMH cut-off values for the number of corpus luteum, total embryo, and transferable embryos were detected as 234, 227, and 210 pg/mL, respectively. CONCLUSION These findings demonstrate that a high serum AMH level has a positive influence on the superovulation response. AMH can be used as a reliable marker for the selection of donors in Holstein cows.

Abstract
This study aims to investigate the relationship between metabolic parameters and the number of embryos produced in superovulated cows with high genetic characteristics in milk yield. Eighteen Holstein donors were treated with classic superovulation protocols, AI and flushing. During superovulation, decreasing doses of FSH (follicle-stimulating hormone) were administered at 12-h intervals for 4 days. Plasma insulin-like growth factor (IGF1), glucose (GLU), beta-hydroxybutyric acid (BHB), non-esterified fatty acid (NEFA), blood urea nitrogen (BUN) and total protein (TP) levels were determined by using an autoanalyzer. The mixed model analysis of variance was used for statistical analysis. As a result, plasma IGF1, BHB and BUN had significant interactions with both groups and days (p < .05). Additionally, plasma TP-days interactions were significant (p < .05). Furthermore, there was a negative correlation between the number of embryos and plasma BHB levels (p < .05). In conclusion, under appropriate environmental conditions, metabolic profile control of donors can contribute to the embryo production process and to the studies on the metabolic infrastructure.

Abstract
Anti-Müllerian hormone (AMH) levels in the blood of dairy cattle are associated with the count of antral follicles (AFC), ovarian function. Numerous studies, particularly in human medicine, have shown that vitamin D3 (Vit D3) has a positive effect on AMH levels. To our knowledge, the effects of Vit D3 on serum AMH levels in heifers have not been investigated. The goal of the current study was to evaluate the concentrations of serum AMH in dairy heifers following Vit D3 treatment. The study included 20 healthy non-pregnant Holstein Friesian heifers. These animals came to estrus at least once. All heifers received a single intramuscular dosage of 5 million IU Vit D3 (Cholecalciferol). Blood samples were collected from the coccygeal veins of all animals before and after Vit D3 injection (days 7, 14, and 28) for the measurement of AMH and 25(OH)D concentrations. In our analysis, we observed that after exogenous Vit D3 administration, circular 25(OH)D increased constantly (up to day 28 after Vit D3 injection) in all animals. On day 28, AMH concentrations saw a 10% increase in comparison with those measured the day before the Vit D3 injection. However, a comparison of AMH concentrations measured across days did not reveal statistically significant differences between Day 0, 7, 14, and 28 levels (p = .10). Furthermore, no statistical correlation was observed between the pairs (age-AMH) and (weight-AMH). Considering all times, no correlation was found between 25(OH)D and blood AMH levels. These findings demonstrated that exogenous Vit D3 did not affect serum AMH in Holstein Friesian heifers.

Abstract
The aim of this study was to compare embryo production efficiency in Flemish and Holstein donor females using ovum pick-up and in vitro fertilization (OPU-IVF) or in vivo production (superovulation; SOV) procedures. The study was conducted using a split-plot design, with eight Flemish and eight Holstein non-lactating cycling females. Females were subjected to ten weekly OPU/IVF sessions and/or two SOV/embryo collections sessions at a 63-day interval, for a total of 160 OPU-IVF and 32 SOV sessions. Mean numbers of follicles and corpora lutea, and cumulus-oocyte complex (COC) recovery rates were similar between breeds after the OPU and SOV sessions. However, Flemish donors yielded better quality grade II COCs (301, 41.9%) than Holstein females (609, and 202, 33.1%). Also, cleavage and blastocyst rates, and the total number and the mean number of viable embryos obtained after OPU-IVF were higher in Flemish (49.6% and 11.8%, and 63 and 11.8 per donor, respectively) than in Holstein (32.8% and 7.2%, and 34 and 7.2 per donor, respectively) females. Flemish females were also more efficient in yielding viable embryos after SOV (111, 7.3 per donor) than Holstein (48, 3.3 per donor) females. Overall, Flemish donor females had better responses to OPU-IVF or SOV procedures than Holstein counterparts. Irrespective of the breeds, SOV procedures were more efficient than OPU-IVF in yielding more viable embryos, under the conditions of this study. Both reproductive procedures were useful tools for the genetic conservation of the Flemish cattle breed in Southern Brazil.

Abstract
El experimento tuvo dos fases, la primera determinó la relación entre el recuento de folículos antrales (RFA) y la concentración de la hormona anti-mülleriana (AMH) valorada el día de reinicio de la onda folicular en 61 vaquillas Holstein mestizas, criadas en ganaderías del trópico alto del Ecuador. La segunda fase comparó el RFA valorado el día de la aspiración ecoguiada (OPU); así como, la cantidad y calidad de los complejos cumulus ovocito (COCs) recuperados en animales con alta (n=8) y baja (n=8) concentración de AMH. La sincronización de la onda folicular en la primera fase se realizó con benzoato de estradiol más un implante de progesterona intravaginal (DIV) y prostaglandina (PG). El RFA y la toma de las muestras de sangre en la primera fase del experimento se realizó el día 11 del protocolo. Se establecieron valores de corte de AMH mayores a 0,12 ng·mL-1 para el grupo de alta y de 0,05 ng·mL-1 para el grupo de baja concentración de AMH. La concentración de AMH el día 0 (inicio de la onda folicular) fue de 0,13 ± 0,01 ng·mL-1, con un RFA de 17,31 ± 0,69 folículos y una correlación alta y positiva entre la AMH y el RFA de r=0,93; P<0,001. En la segunda fase del experimento se observó que las vaquillas con alta concentración de AMH presentaron el doble de folículos y COCs comparadas con las de baja concentración; sin embargo, el porcentaje de recuperación fue similar (57 %) en los dos grupos. Se ratificó la existencia de una correlación alta y positiva entre el RFA y la concentración de la AMH; además, se observó una relación fuerte entre la AMH y la cantidad y calidad de COCs recuperados por OPU. Vaquillas con más de 12 ng·mL-1 deberían ser seleccionadas como donadoras de ovocitos, pues proporcionaron el doble de COCs aptos para la producción de embriones in vitro (PIVE), lo cual influirá en la cantidad y calidad de embriones obtenidos al final de la PIVE.

Abstract
This study aimed to determine effects of exposure of recipient dairy heifers to heat stress (THI≥ 73) during the estrous cycle coinciding with embryo transfer (ET) on the risk of pregnancy establishment after transfer of in vivo produced embryos. Recipients exposed to THI values ≥ 73 during days zero (recipient estrus), 7 (day of ET), 14 (seven days after ET), 15 and 16 (maternal recognition of pregnancy) of the ET cycle were considered as heat stressed heifers (n=254), while heifers in the control group (n=470) were not exposed to THI≥ 73 at any of the previous days. Results revealed no significant effects of any of the investigated factors on the risk of pregnancy following ET. However, the mean THI above 77 was associated with a drastic numerical decrease in PR/ET (36.63%), when compared to a mean THI 72 (78.78%). In addition, PR/ET after transfer of second and third grade embryos were numerically lower in heat-stressed recipients, compared to first grade embryos (41.17 vs 56.36%, respectively). Our findings confirmed that transfer of blastocysts were associated with numerically higher PR/ET in heat stressed and control recipients, as compared to morula stage. Interestingly, PR/ET tended to be higher when sexed embryos were transferred to the control recipients compared to heat-stressed ones. In conclusion, PR/ET in dairy heifers was not significantly affected by heat stress during critical windows of their estrous cycle coinciding with ET, whereas transfer of sexed embryos gives lower results under conditions of heat stress.

Abstract
Cadmium, a toxic heavy metal that occurs in the environment in large quantities through human activities, has been shown to have adverse effects on female reproductive health. However, the association between cadmium exposure and primary ovarian insufficiency (POI), one of the most prevalent ovarian diseases in women, has not been examined yet. This case-control study involving 169 POI cases and 209 healthy controls was conducted in Zhejiang Province, China. The urinary concentrations of cadmium were determined by inductively coupled plasma mass spectrometry (ICP-MS). In addition, serum levels of reproductive hormones, including follicle-stimulating hormone (FSH), luteinizing hormone (LH), anti-Mullerian hormone (AMH) and estradiol, were measured. The median concentration of urinary cadmium in POI cases (0.43 μg/L, 0.58 μg/g for creatinine adjustment) was significantly higher than that of controls (0.29 μg/L, 0.43 μg/g for creatinine adjustment). The results of binary logistic regression models showed that the concentrations of urinary cadmium were positively significantly correlated with the odds ratio (ORs) of POI before the adjustment of confounders. After the adjustment, a significantly positive association was still present between the increased concentrations of cadmium and the ORs of POI (2.50, 95% CIs: 1.34-4.65 for the third tertile, p for trend = 0.001). The serum levels of FSH and LH were positively associated with urinary cadmium, while AMH and estradiol levels were inversely correlated. To the best of our knowledge, this is the first reported positive association of cadmium exposure with the risk of POI in women.

Abstract
The goal was to investigate the relationship among mRNA expressions of anti-Mullérian hormone (AMH), follicle-stimulating hormone receptor (FSHR) and responses to superovulation (SO) in embryo donor dairy cows. Holstein cows (n = 19) were submitted to a standard SO protocol, with twice daily FSH treatments, and artificially inseminated. Prior to SO (Day 0), relative mRNA expressions of AMH and FSHR in blood were determined for all cows. Day 7 embryos were collected and were graded to determine superovulatory response for each donor. Results showed that relative mRNA expressions of AMH and FSHR were positively correlated (R2 = 0.94). Relative mRNA expressions of both AMH and FSHR were positively correlated with total embryos (R2 = 0.68 and 0.69, respectively), total transferable embryos (R2 = 0.92 and 0.97, respectively) and total grade 1 embryos (R2 = 0.54 and 0.59, respectively). Further, transcript abundances of AMH and FSHR positively associated with milk production of donor cows, and meanwhile, they were negatively associated with days in milk (DIM) at submission of cows to SO (p < .05) protocol. The relative mRNA expression of AMH was higher (p < .05) in donor cows <5 years of age. However, age of donor at superovulation did not influence mRNA expression of FSHR. Collectively, we infer that the mRNA expressions of AMH and FSHR prior to superovulation can predict donor cows' positive response to superovulation.

Abstract
Despite a long history of bovine superovulation research, significant commercial applications did not start until the early 1970s. For some 20 years thereafter, superovulation represented the primary tool for the production of cattle embryos. In the early 1990s, commercial invitro production (IVP) was initiated in cattle. Although ovum pick-up and IVP are now commercially practiced on a wide scale, superovulation and embryo recovery by flushing remain a widespread and very effective approach to the production of cattle embryos. This review covers both the history and the effects of multiple factors on superovulation in Bos taurus cattle. There are three general protocols for suitable pre-FSH programming of donors so that gonadotrophin-responsive follicles are available. Superovulation protocols vary widely based on the FSH source, the diluent used, the number and timing of FSH injections and the timing and utilisation of various prostaglandins, controlled internal progesterone releasing devices, gonadotrophin-releasing hormone, and other means of controlling follicular development and ovulation. The number of oocytes that can be stimulated to grow and ovulate within any given donor can be estimated by either ultrasound-guided sonography or by measuring concentrations of anti-Müllerian hormone in the blood. Animal-related factors that can influence the efficacy of superovulation include cattle breed, age, parity, genetics, lactational status and reproductive history. In addition, nutrition, stress, season, climate, weather and several semen factors are discussed.

[PMID: 32062150 DOI: 10.1016/j.theriogenology.2020.02.006] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2019] [Revised: 11/10/2019] [Accepted: 02/04/2020] [Indexed: 12/12/2022]
Abstract
The objective was to determine associations between response to superovulation and body condition, subclinical endometritis and circulating metabolic biomarkers [adiponectin, leptin, insulin, IGF1, tumor necrosis factor (TNF) α, interleukin (IL) 1β, IL6, and urea] in lactating dairy cows. Ten multiparous lactating Holstein cows in each body condition score (1-5; 1 emaciated; 5 obese) category (BCSC) 2.00 to < 2.50 (BCSC1), 2.50 to < 3.00 (BCSC2), 3.00 to <3.50 (BCSC3), 3.50 to <4.00 (BCSC4) and 4.00 to 5.00 (BCSC5) groups (total n = 50) were randomly selected and superovulated, timed artificially inseminated with frozen-thawed semen from three sires and embryos collected (n = 50 collections). At embryo collection, blood samples and embryo recovery fluid were collected for determination of metabolic markers and presence of subclinical endometritis (lavage technique; > 6% PMN). In total, 379 embryos were collected (average of 7.6 embryos per superovulation). Mean numbers of total ova and embryos was greater for cows in BCSC2, BCSC3 and BCSC4 groups compared with cows in BCSC1 and BCSC5 groups (P < 0.01). Total number of transferrable embryos were greater for cows in BCSC 2 and BCSC3 groups compared with cows in BCSC1, BCSC4 and BCSC5 groups (P < 0.01). Mean number of total ova and embryos and of transferrable embryos was higher for cows with 0 or 1-6% PMN compared to cows with >6% PMN (P < 0.01). In addition, there was a quadratic association between blood urea nitrogen concentrations and % transferrable embryos (r2 = 0.85; P < 0.05) and between BCS and % transferrable embryos (r2 = 0.73; P < 0.05). Circulating adiponectin, leptin, insulin, IGF1 and TNFα were greater in cows with moderate to good body condition compared to thin or obese cows (P < 0.05). Circulating adiponectin, leptin, IGF1 and insulin were greater in normal cows (≤6% PMNs), whereas, TNFα and IL1β and IL6 were greater in cows with subclinical endometritis (P < 0.05). In conclusion, BCS and subclinical endometrial inflammation were associated with superovulatory response and embryo quality. Further, circulating metabolic biomarkers were associated with superovulatory response and embryo quality, likely due to donor's metabolic status and uterine environment. Optimizing superovulatory responses and embryo quality in lactating dairy cows requires management of nutrition and uterine health.

The effect of anti-müllerian hormone and progesterone concentrations on superovulation response and embryo yield in goats. Theriogenology 2019; 143:1-9. [PMID: 31816457 DOI: 10.1016/j.theriogenology.2019.11.041] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2019] [Revised: 11/29/2019] [Accepted: 11/30/2019] [Indexed: 11/21/2022]
Abstract
We aimed to evaluate the relationship of anti-Müllerian hormone (AMH) and progesterone concentrations with superovulation response in goats and to determine donors exhibiting better superovulation response by measuring AMH concentrations. For this, blood samples were collected from multiparous Angora goats (n = 24) for measuring the progesterone and AMH concentrations on the day the synchronization protocol was initiated (Day 0), on the day of the first FSH administration (Day 9), on the day the progesterone source was removed (Day 11), and on the day of uterine flushing. Descriptive statistics (mean, standard deviation, median, minimum value, maximum value, and percentile) were given for superovulation response and embryo yield. To compare the differences between the two groups, the Student's t-test was used. The relationship between two continuous variables was assessed by the Pearson Correlation Coefficient. The AMH cutoff values in superovulation responses were evaluated by ROC analysis on the day the synchronization protocol was initiated. A strong positive correlation was found between the AMH concentrations measured on the day the synchronization protocol was initiated (Day 0), on the day of the first FSH administration (Day 9), and on the day of removal of the progesterone source (Day 11) and the count of total corpus luteum (CL), total oocyte/embryo, transferable embryo, and Code I quality embryo (P < 0.05). Furthermore, AMH concentration increased on the day the synchronization protocol was initiated, the donor's superovulation response increased as well. The cutoff value was 4.74 ng/ml, as assessed by the ROC curve analysis conducted for selecting donors exhibiting better superovulation responses. The sensitivity and specificity of the selected cutoff value were found to be quite high (P < 0.01). However, a positive correlation was noted between the progesterone concentrations measured on the day of uterine flushing and total CL count, total oocyte/embryo count, transferable embryo count, and Code I quality embryo count (P < 0.01). In conclusion, it was determined that an increase in AMH concentrations in goats led to an increase in the total CL count, embryo count, and embryo quality and that AMH measurement could be used to identify donors that responded better to superovulation. Additionally, a positive correlation was found between the progesterone concentration measured on the day of uterine flushing and the total CL count, transferable embryo count, and embryo quality.

Hormonal stimulation in 4 to 7 months old Nelore (Bos taurus indicus) females improved ovarian follicular responses but not the in vitro embryo production. Theriogenology 2018; 118:130-136. [PMID: 29906662 DOI: 10.1016/j.theriogenology.2018.05.039] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2018] [Revised: 05/26/2018] [Accepted: 05/29/2018] [Indexed: 01/08/2023]
Abstract
The inclusion of pre-pubertal bovine females in reproductive management could allow in vitro embryo production and reduce generation interval, thereby causing faster genetic gain of the herd. However, oocytes of pre-pubertal females have lower competence, blastocyst production, and pregnancy rates than those collected from pubertal animals. This study aimed to evaluate the effect of an induced hormonal stimulation on the serum concentrations of Anti-Mullerian hormone (AMH) and FSH, ovarian responses, ovum pick up (OPU), and in vitro produced embryos (IVP) from oocytes obtained from four-to seven-months old Nelore female cattle. In a crossover design, these females were randomly allocated into: 1) Treated Group (TG, n = 9): the animals were subjected to a hormonal protocol (implanted progesterone device, estradiol benzoate, LH, and FSH) from Day 0 (the start of the treatment) to Day 7 (OPU day), and 2) Control Group (CG, n = 9): the females did not receive any hormonal stimulation, but they had ablation of their largest follicles on Day 2 of experiment. Blood collection for serum FSH measurements was done on Days 5, 6, 7, and 8, and collection for serum AMH measurements was done on Days 5 and 8. As hypothesized, TG had higher serum FSH concentrations (p < 0.05) on Day 5 (1.16 ± 0.31 ng/mL), Day 6 (1.21 ± 0.45 ng/mL), and Day 7 (0.95 ± 0.26 ng/mL) than CG (0.56 ± 0.17 ng/mL on Day 5, 0.60 ± 0.25 ng/mL on Day 6, and 0.60 ± 0.14 ng/mL on Day 7). However, serum AMH concentrations were neither significantly different (p > 0.05) between CG and TG, nor between the collection days. Hormonal stimulation also increased (p < 0.05) total follicular population (20.0 ± 4.95 CG vs 26.66 ± 4.24 TG), ovarian diameter (13.08 ± 1.0 mm CG vs 14.81 ± 1.38 mm TG) and number of follicles ≥2.5 mm (6.88 ± 2.14 CG vs 11.55 ± 4.09 TG). In TG, grades I and II oocytes predominated, whereas, in CG grades III and IV oocytes were more abundant (p < 0.05). No significant increases (p > 0.05) in the cleavage (49.33% CG vs 51.42% TG), cleavage > 4 cells (9.33% CG vs 16.19% TG), and blastocysts rates (1.33% CG vs 8.57% TG) were seen in TG. This hormonal protocol increased serum FSH concentrations that possibly contributed to increases in the observed follicle, as well as improving oocyte quality. This exogenous hormonal stimulation increased available oocytes numbers for IVP, despite no increase in the in vitro embryo production efficiency.
