The world's population is increasing at an alarming rate and is projected to reach nine billion
by 2050. Despite this, 15% of couples world-wide remain childless because of infertility. Few …

Mammalian fertilization comprises sperm migration through the female reproductive tract,
biochemical and morphological changes to sperm, and sperm-egg interaction in the oviduct …

Understanding mammalian spermatozoan development and the events surrounding
fertilization has grown slowly, in part because of uncertainty about the number and identity of …

Mammalian fertilization is a fascinating process that leads to the formation of a new
individual. Eggs and sperm are complex cells that must meet at the appropriate time and …

Fertilization is defined as the process of union of two gametes, eggs and sperm. When
mammalian eggs and sperm come into contact in the female oviduct, a series of steps is set …

This chapter examines the novel structural features of the spermatozoon, their composition
and assembly, and the mechanisms regulating their function. The spermatozoon is a highly …

An integrated system combining a magnetically‐driven micromotor and a synthetized protein‐
based hyaluronic acid (HA) microflake is presented for the in situ selection and transport of …

Fertilization in mammals requires the successful completion of many steps, starting with the
transport of gametes in the reproductive tract and ending with sperm-egg membrane fusion …

Spermiogenesis is a long process whereby haploid spermatids derived from the meiotic
divisions of spermatocytes undergo metamorphosis into spermatozoa. It is subdivided into …

We produced transgenic mouse lines that accumulate mutated green fluorescent protein
(EGFP) in sperm acrosome, a membrane limited organelle overlying the nucleus. The sperm …
