Based on existing research, it is found that eggs can be fertilized by more than one sperm in mammals, which was delivered by Prof. Maria Jose’ Izquierdo Rico, Ph.D. in One Day International Seminar held at the end of May by the Biology Education and Animal Husbandry departments of the University of Muhammadiyah Malang.

As Maria noted, the research finding has become one of the problems in Europe. Therefore, Maria and other lecturers from Universidad de Murcia, Spain, conducted a deeper study of the research result. “The research carried out was on the zona pellucida of mammals. The zona pellucida is a matrix that protects the egg and embryo from mechanical damage during ovulation. It also plays a vital role in spermatozoa binding,” explained Maria.

Also, she added that the zona pellucida is essential in successful insemination, and so is the zona pellucida in the ovum, which has different characters and specifications in every animal.

Bringing the theme “Trend in Reproductive Technology and Biology Research”, this seminar aimed to provide the latest information and inspire researchers, especially those specializing in biology and reproduction. That said, it can improve the passion and enthusiasm to research further, discover a new phenomenon, and contribute to science development.

Besides Maria, Prof. Francisco Alberto Garcia Vazquez, Ph.D., from the same university, presented material about sperm selection in the reproductive process. This selection is called Artificial Insemination. “This sperm selection aims to make artificial oviducts with bioprinting techniques using the decellularized extracellular matrix (dECM) method, also evaluating the toxicity of tissues obtained from incubation with spermatozoa and oocytes,” elaborated Fransisco.

On the other hand, Prof. Dr. Rr. Eko Susetyarini M.Si., the Head of the Biology Education of UMM, explained the development of bioinformatics research. According to him, bioinformatics development initially focused on DNA information only. However, increasingly here, the development of bioinformatics is getting faster. One example is to design the candidate drug molecules (drug design) and the relationship of a plant species. (imh/zak/wil)
