Question

Calcium2+ is very important for fertilisation in humans. In the absence of Calcium2+ fertilisation does not occur. Comment

Answer 1

if lack of calcium in our body than our bone is tight and start pain. lack of calcium is also responsible less flexible in body

Answer 2

Hi mate.

Thanks for asking this question.

Here is your answer,




1. Calcium plays an important role in

our muscle contractions and signaling during

mammalian fertilization . The initial

development of embryo depends upon the

increased level of calcium ions in the egg,

which generally increased during fertilization.

The egg activation signals can be emitted by

increasing level of calcium ions. This is a first

stage of the embryo development

2. Roles of Ca2+ and Ca2+binding proteins during sperm activation

Depletion of extracellular Ca2+ by treating spermatids with EDTA or EGTA does not compromise sperm activation, which suggests that Ca2+from extracellular environment may not play a role in sperm activation .

The role of Ca2+ in triggering oocyte maturation is less clear, although preventing intracellular Ca2+ changes can inhibit meiotic maturation at specific stages.

Thank you.
