Thyroid hormone receptor (THR) α and THRβ mediate the genomic action of thyroid hormones (THs) that affect bovine embryo development. However, little is known about THRs in the preimplantation embryo. The aim of the present study was to investigate

So far, the characteristics of a good quality egg have been elusive, similar to the nature of the physiological, cellular, and molecular cues leading to its production both in vivo and in vitro. Current understanding highlights a strong and complex i

When examining gene expression profiles for the purposes of assessing embryo quality, it is imperative that sex be considered, because many embryonic transcripts have sex-related expression patterns. The objective of this study was to systematically

The aim of this study was to determine and compare the concentrations of total (T) and free (F) fractions of thyroid hormones (T3-triiodithyronine and T4-thyroxin) in peripheral circulation and follicular fluid of cows in relation to ovarian follicul

Early embryo development (EED) forms the basis of assisted reproductive technologies (ARTs), which are used to treat human infertility and to propagate other mammalian species. Thyroid hormones (THs) play an important role in the post-implantation de

SummaryThyroid hormones (THs) have been shown to improve in vitro embryo production in cattle by increasing blastocyst formation rate, and the average cell number of blastocysts and by significantly decreasing apoptosis rate. To better understand tho

Contents With the advancement of assisted reproductive biotechnologies, preselecting the sex of offspring has become an important goal for cattle and other livestock breeding as well as for research. The aim of this study was to investigate the feasi

Sexual dimorphisms such as differences in growth rate and metabolism have been observed in the early embryo, suggesting that sex chromosome-linked gene expression may play an active role in early embryo development. Furthermore, in vitro sex ratios a

Thyroid hormones (TH) play an important role in the physiology of vertebrates, ranging from the regulation of metabolic processes to cell proliferation, differentiation, and embryo development. We have previously shown a beneficial effect of suppleme

Testis-specific protein, Y-encoded (TSPY) is a gene found on the Y chromosome that, like many genes on the Y chromosome of mammalian species, has multiple copies. Humans have between 20–60 copies, whereas cattle can have up to 200 copies. Genomic c
