Female reproductive aging is a normal phase of life that eventually leads to menopause and reproductive senescence. The current experimental investigation was intended to study zinc supplementation effects on early embryonic development and neonates in 26-28 weeks old female mice. In this investigation, 80 mature female mice were used that were divided into two groups of forty each. Two control groups received distilled water, while two Zn groups were given 0.115 mg/kg/day Zn orally daily during 2-3 estrous cycles. The female mice were all mated with adult males. Twenty female mice from both the control and Zn groups were euthanized by CO2 gas inhalation, and then a longitudinal incision in the abdomen of each female mouse was performed and uterine horns and oviducts were detached from the body in order to obtain two-cell embryos. On the other hand, 20 pregnant mice from each group were permitted to complete their pregnancy until birth and then their neonates were collected for macroscopic examination. The findings showed that the Zn supplementation significantly (P≤0.01) improved the mean embryonic development and the quality of 2-cell stage embryo grade A. Whereas, it decreased the mean embryonic development of 2-cell stage embryo grade D in aged female mice significantly (P≤0.01) in comparison with aged control groups. Also, the count and quality of neonates from Zn-treated aged female mice enhanced significantly (P≤0.01) as compared to non-treated aged female mice. It was concluded from these findings that the Zn can improve embryonic development and neonate count and quality in aged mice.

Approximately 15% of all couples all over the world suffer from difficulty conceiving their first child. The word "infertility" is used to describe this problem.
When a couple had regular, unprotected sexual intercourse for a year or longer, it indicates that they have been unsuccessful in their efforts to conceive.
The current investigation aims to find out if there is a relationship between PROTAMIN-1(PRM-1) and INTERLEUKINE-12 (IL-12) gene expressions and their effect on the development of infertility. The current investigation comprised 100 teratozoospermia patients and 100 healthy fertile controls who had their semen examined. Samples were given by Al-Nahrain University's Biotechnology Research Center and the Kamal Al-Samarie IVF Hospital in Baghdad, Iraq. Determinations Reverse Transcription quantitative Polymerase Chain Reaction (RT-qPCR) was employed to test the expression of the PRM gene in semen and blood samples, as well as the IL-12 gene in blood samples. And the titer of IL-12 was evaluated in the seminal plasma employing the Enzyme Linked Immune Sorband Assay (ELISA) technique. The difference between the mean threshold cycle (ΔCt) of PRM-1 and IL-12 mRNA in the infertile patient group versus the healthy control group was also statistically significant. Evaluating the means of 2 ̄ΔΔCt revealed an important finding, a decrease in the expression of PRM-1 mRNA in the infertile group in comparison to the control group in the two types of samples. Conversely, there was an increase in the expression of IL-12 mRNA between the two study groups. In infertile Iraqi men, the expression of the PRM-1 gene was found to be down-regulated, whereas the expression of the IL-12 gene was found to be up-regulated. Our data revealed the diagnostic value of these genes and might be considered as predictive biomarkers in infertile people with idiopathic infertility.
