Egg and sperm necklace | sterling silver
The moment before fertilisation — egg and sperm, the two cells whose meeting initiates the entire cascade of human development.
Fertilisation
The human egg (oocyte) at the time of fertilisation is arrested at metaphase II of meiosis, awaiting completion of meiotic division upon sperm entry. It is the largest cell in the human body at roughly 120 micrometres in diameter. Sperm cells, by contrast, are among the smallest — roughly 60 micrometres end-to-end, highly streamlined for motility. Of the 200–500 million sperm deposited at intercourse, only a few hundred reach the fallopian tube, and only one typically fertilises the egg. Fertilisation occurs when a sperm penetrates the zona pellucida and fuses with the egg plasma membrane, triggering the cortical reaction — a wave of exocytosis that modifies the zona pellucida to prevent polyspermy — and completing meiosis II to form the diploid zygote.
