BACKGROUND Spermatozoa are highly differentiated, transcriptionally inert cells
characterized by a compact nucleus with minimal cytoplasm. Nevertheless they contain a …

BACKGROUND Spermatogenesis generates a small and highly specialised type of cell that
is apparently incapable of transcription and translation. For many years, this dogma was …

Spermatogenesis is a highly regulated process that produces sperm to transmit genetic
information to the next generation. Although extensively studied in mice, our current …

In mammals, male gametes are produced inside the testis by spermatogenesis, which has
three phases: mitotic proliferation of spermatogonia, meiosis of spermatocytes, and haploid …

Spermatogenesis is a complex process in the testis and is a cornerstone of male infertility.
The abundance of unsaturated fatty acid and high cell division rate make male germs cells …

Although male factors account for approximately 50% of all infertility, the mechanisms
underlying their origin are unknown. Currently, clinicians rely primarily on semen analyses …

Among infertile couples, 25% involve both male and female factors, while male factor alone
accounts for another 25% due to oligo-, astheno-, teratozoospermia, a combination of the …

Background Infertility in dairy cattle is a concern where reduced fertilization rates and high
embryonic loss are contributing factors. Studies of the paternal contribution to reproductive …

Infertility is a common problem affecting one in six couples and in 30% of infertile couples,
the male factor is a major cause. A large number of genes are involved in spermatogenesis …

Sperm DNA methylation abnormalities have been detected in oligozoospermic men.
However, the association between sperm DNA methylation defects, sperm parameters and …
