Serum and Seminal Plasma Zinc Levels and Immunopositivity of the ZIP6 and ZIP14 Transporters in Men with Normo- and Teratozoospermia

Current Issues in Molecular Biology
Zinc plays a crucial role in spermatogenesis, sperm function, and fertilisation. Zinc homeostasis is regulated by ZIP and ZnT transporter proteins, which mediate Zn2+ influx and efflux across sperm cell membranes.

Angiotensin-converting Enzyme Insertion/Deletion Polymorphism Distribution in the North Indian Population of Jammu and Kashmir and Its Positive Correlation with Male Infertility: A Case Control Study

Journal of Human Reproductive Sciences
Background: A precise balance among angiotensin-converting enzyme (ACE), angiotensin-II (Ang-II) and Ang-II type 1 receptor is essential for spermatogenesis. Any alteration in this balance can potentially lead to infertility.
