Article Abstract
In vitro and in vivo intraluminal perfusions of the uterovaginal junction of the oviduct were performed in an attempt to quantitate sperm release from the uterovaginal sperm host glands (UV-SHG) of breeder hens. Spermatozoa were present in the perfusate at all time periods examined. However, the quantity of spermatozoa recovered showed a significant (P<0.0001) decline over a 2-h perfusion period in all experiments. Furthermore, histological examination of the perfused oviduct revealed significantly lower percentages (P<0.05) of UV-SHG containing spermatozoa compared to unperfused control oviducts. The perfusion techniques used in this study seemed to influence the pattern of sperm release from the storage glands.

Doxorubicin (DOX) is a powerful antineoplastic FDA-approved anthracycline-derived antibiotic and is considered as the most suitable intervention for solid tumors and hematological cancers therapy. However, its therapeutic application is highly limited due to acute and chronic renal, hematological and testicular toxicity. Oxidative stress, lipid peroxidation and apoptosis in germ cells as well as low sperm count, motility and disturbing steroidogenesis are the principal machineries of DOX-induced testicular toxicity.

Background: Both intramural myomas and thin endometrium exert a detrimental influence on the outcomes of assisted reproductive technology (ART). The downregulation of gonadotropin releasing hormone agonists (GnRH-a) is regarded as an effective approach to reducing the size of intramural fibroids and enhancing endometrial receptivity. Consequently, we conducted this study to assess whether the GnRH-a combined with hormone replacement therapy (GnRH-a-HRT) can improve reproductive outcomes in frozen embryo transfer cycles for patients with a thin endometrium (≤7 mm) and intramural fibroids.

Sperm cryopreservation is widely used in assisted reproductive technology (ART) and livestock breeding. Although sperm cryopreservation accelerates breeding, the quality of cryopreserved sperm tends to be decreased. Improving the quality of frozen sperm is a hot topic, and spirulina polysaccharide, known for its immunomodulatory and antioxidant properties, is considered a promising natural extract for extensive studies.

The physical abrasion of plastics from simple everyday entered the food chain, with associated risks recently emphasized. Although many studies have reported the adverse effects of microplastics (MPs) on human, the reproductive implications of continuous exposure to physically abraded polyethylene terephthalate (PET)-MPs remain unexplored. Ingestion of physically abraded PET-MPs (size range: 50-100 µm) in mice from 5 to 34 weeks of age at an annual intake relevant dose of MPs (5 mg week) significantly impaired male reproductive function.

Preserving fertility is important in men under radiation therapy because healthy cells are also affected by radiation. Supplementation with antioxidants is a controversial issue in this process. Designing a biocompatible delivery system containing hydrophobic antioxidants to release control may solve these disagreements.
