Background: In vitro maturation (IVM) of germinal vesicle intact oocytes prior to in vitro fertilization (IVF) is practiced widely in animals. In human assisted reproduction it is generally reserved for fertility preservation or where ovarian stimula...

Humans are ubiquitously exposed to complex mixtures of environmental chemicals (ECs). This study characterised changes in post-natal and peripubertal growth, and the activation of the reproductive axis, in male and female offspring of sheep exposed t...

Developmental exposure to a real-life environmental chemical mixture alters testicular transcription factor expression in neonatal and pre-pubertal rams, with morphological changes persisting into adulthood (2023)
Journal Article
Elcombe, C. S., Monteiro, A., Ghasemzadeh-Hasankolaei, M., Padmanabhan, V., Lea, R., Sinclair, K. D., …Bellingham, M. (2023). Developmental exposure to a real-life environmental chemical mixture alters testicular transcription factor expression in neonatal and pre-pubertal rams, with morphological changes persisting into adulthood.

Environmental chemical (EC) exposure may be impacting male reproductive health. The translationally relevant biosolids treated pasture (BTP) sheep model was used to investigate gestational low-level EC mixture exposure on the testes of F1 male offspr...

Enhanced progesterone support during stimulated cycles of transvaginal follicular aspiration improves bovine in vitro embryo production (2023)
Journal Article
Simmons, R., Tutt, D. A., Tutt, D. A., Guven-Ates, G., Kwong, W. Y., Labrecque, R., …Sinclair, K. D. (2023). Enhanced progesterone support during stimulated cycles of transvaginal follicular aspiration improves bovine in vitro embryo production. Theriogenology, 199, 77-85. https://doi.org/10.1016/j.theriogenology.2023.01.003

The in vitro production (IVP) of cattle embryos requires that germinal-vesicle stage oocytes undergo a period of maturation in vitro prior to fertilization and culture to the blastocyst stage. Success of IVP in taurine cattle is enhanced following ov...
