Summary
Selenium and zinc-enriched duck embryo egg (SZDE) powder is safe and effectively reduces inflammation in rats with prostatitis. This dietary supplement may offer a new strategy for improving prostate health.
Area of Science:
- Nutritional Science
- Immunology
- Reproductive Biology
Background:
- Selenium and zinc are vital for immune function and reproductive health.
- These elements have demonstrated potential in managing prostatitis and modulating reproductive performance.
- Duck embryo egg (SZDE) powder is rich in selenium and zinc.
Purpose of the Study:
- Analyze the composition of SZDE, focusing on trace elements and oligopeptides.
- Evaluate the acute toxicity of SZDE.
- Investigate the anti-inflammatory effects of SZDE in a rat model of prostatitis.
Main Methods:
- Compositional analysis of SZDE.
- Acute toxicity testing in male and female mice.
- Construction of a prostatitis rat model.
- Assessment of inflammatory markers, androgen levels, and the MAPK/p38 pathway.
Main Results:
- SZDE exhibited significantly higher levels of selenium and zinc compared to normal eggs.
- SZDE demonstrated no observable toxicity in mice.
- SZDE intervention led to reduced pro-inflammatory cytokines and increased androgen levels (P < 0.05).
- SZDE treatment significantly improved prostatitis by inhibiting the MAPK/p38 pathway (P < 0.05).
Conclusions:
- SZDE is safe for consumption.
- SZDE possesses significant prostatitis-regulating effects.
- SZDE may represent a novel dietary approach for maintaining prostate health.

During fertilization, an egg and sperm cell fuse to create a new diploid structure. In humans, the process occurs once the egg has been released from the ovary, and travels into the fallopian tubes. The process requires several key steps: 1) sperm present in the genital tract must locate the egg; 2) once there, sperm need to release enzymes to help them burrow through the protective zona pellucida of the egg; and 3) the membranes of a single sperm cell and egg must fuse, with the sperm...

01:22Sperm Structure and Semen Composition
16.7K
During ejaculation, males release around 2-5 milliliters of semen, which is a complex mixture of mature sperm and various fluids produced by accessory glands. The mature sperm cells measure approximately 60 micrometers in length and consist of a head, neck, midpiece, and tail. The head is flattened and tapered, measuring about 4 to 5 micrometers in length. It contains a nucleus with condensed chromosomes and an acrosome, a cap-like structure filled with enzymes essential for penetrating the...

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
