Abstract
Anti-Müllerian hormone (AMH) reflects the population of growing follicles and has been related to mammalian fertility. In the horse, clinical application of ovum pick-up and intracytoplasmic sperm injection (OPU-ICSI) is increasing, but results depend largely on the individuality of the mare. The aim of this study was to assess AMH as a predictor for the OPU-ICSI outcome in horses. Therefore, 103 mares with a total follicle count above 10 were included in a commercial OPU-ICSI session and serum AMH was determined using ELISA. Overall, the AMH level was significantly correlated with the number of aspirated follicles and the number of recovered oocytes (p < 0.001). Mares with a high AMH level (≥2.5 µg/L) yielded significantly greater numbers of follicles (22.9 ± 1.2), oocytes (13.5 ± 0.8), and blastocysts (2.1 ± 0.4) per OPU-ICSI session compared to mares with medium (1.5-2.5 µg/L) or low AMH levels (<1.5 µg/L), but no significant differences in blastocyst rates were observed. Yet, AMH levels were variable and 58% of the mares with low AMH also produced an embryo. In conclusion, measurement of serum AMH can be used to identify mares with higher chances of producing multiple in vitro embryos, but not as an independent predictor of successful OPU-ICSI in horses.

Superovulation, embryo recovery, and pregnancy rates from seasonally anovulatory donor mares treated with recombinant equine FSH (reFSH). Theriogenology 2019; 142:291-295. [PMID: 31711702 DOI: 10.1016/j.theriogenology.2019.10.030] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2019] [Revised: 10/18/2019] [Accepted: 10/28/2019] [Indexed: 11/18/2022]
Abstract
The effectiveness of different treatments with recombinant equine FSH to stimulate follicular growth, multiple ovulations and embryo production in seasonally anovulatory mares was evaluated. During mid-winter season (July-August in Argentina, South America) forty light breed donor mares, presenting follicles <10 mm in diameter and no CL at ultrasound examination (deep-anestrus), were randomly assigned (n = 10/group) to one of the following treatments: Group 1: twice daily intramuscular (IM) injections of 0.65 mg reFSH (AspenBio Pharma, CO), Group 2: once daily IM injection of 1.3 mg reFSH, Group 3: twice daily IM injection of 0.32 mg reFSH, and Group 4: once daily IM injection of saline (control). Treatment was administered until a follicle of 35 mm was observed or for a total period of 10 days. When the largest follicle reached ≥35 mm in diameter, treatment was discontinued and 2500 IU hCG was injected intravenously (IV) 36 h later. Mares receiving hCG were inseminated with fresh semen every 48 h until ovulation(s) were detected or one dose of frozen semen (250 × 106 motile sperm) after the first ovulation was detected. Eight days after first ovulation, transcervical embryo recovery was performed. Recovered embryos were non-surgically transferred to anovulatory estrogen/progesterone treated recipients and pregnancy diagnosed by ultrasonography 7, 14 and 21 days later. All mares receiving reFSH, but none receiving saline control, responded to the treatment with follicular growth. On average, 6.5 days of reFSH treatment were required for mares to develop follicles of ovulatory size (>35 mm). Ovulations were detected in 80% of mares in Groups 1 and 2, 50% of mares in Group 3 and in none of Group 4 (Control). Among ovulating mares, no differences in number of ovulations, number of embryos recovered, or pregnancy rates were observed among reFSH treatments. Of treated mares, 6, 7, and 5 produced embryos in Groups 1, 2, and 3, respectively. The average embryo recovery rate per ovulated mare was 88%. The average embryo recovery rate per ovulation was 43%. Overall, a 59% pregnancy rate was achieved. These results indicate that treatment with reFSH during deep anestrus results in follicular development, ovulation of fertile oocytes, and production of embryos that established viable pregnancies after transfer. Also, a single daily administration of reFSH was as effective as two daily administrations, which allows for a simplified administration regimen.
