Özet

Boron (B) is the 5th element in the periodic table and is found in nature as

borax, boron, boric acid, colemanite, kernite, ulexite, and borate (4). It also

plays a role in the absorption and balance of phosphorus, magnesium, and

calcium in bones and joints (5, 10, 11). Although the biochemical mechanism

of boron is not fully known, it is thought that it may be a metabolic regulator

in cell membrane functions (12) and enzymatic system (5). In addition, it also

has antibacterial and antifungal effects. There are a limited number of studies

in the literature regarding animal embryo culture with boron or boric acid.

The first study on embryo development in the literature found that 12-25 μM

boric acid supported blastocyst development with the addition of mouse

embryo culture (9). There were several studies on animal reproduction of

boron for potential beneficial effects (1, 3, 6-8, 13). In addition, in a recent

study, 20-250 μM/L boric acid as an antioxidant did not support embryo

development after developing in vitro bovine embryo culture conditions (7).

According to the latest research in the literature; after adding 2, 1 and 0.4 μg

of boric acid to the in vitro culture medium for bovine embryo development,

blastocyst development was 47%, 49%, 54%, respectively, and a significant

difference was observed positively compared to the control group. In this

study, the highest improvement was achieved especially in the low dose 0.4

μg boric acid group (13). In our study, boric acid at doses of 1.62x10-1 μM,

1.62x10-3 μM, 1.62x10-5 μM was added to the in vitro maturation medium of

ovine oocytes obtained from the slaughterhouse and incubated for 24 hours

to mature and reach the MI stage.
