Judaism's stance on egg and sperm donations can vary among different denominations and communities. Generally, Orthodox Judaism may have more restrictions due to concerns about lineage and the sanctity of procreation, while Conservative and Reform Judaism tend to be more accepting of such practices. Many Jewish authorities emphasize the importance of fulfilling the commandment to be fruitful and multiply, which can lead to support for assisted reproductive technologies, including donations. However, specific guidance often depends on individual circumstances and rabbinic interpretation.
The egg need pores because the roaster need to produce sperm
An acrsome is an organelle that develops over the anterior half of the sperm's head. Its purpose is to break down the outer layer of the ovum so the sperm can join the egg.
they have long tails for swimming and heads to get into the ovum
Sperm have a streamlined shape and a flagellum that allows them to swim efficiently through the female reproductive tract in search of the egg. They also contain enzymes that help to penetrate the outer layers of the egg for fertilization to occur. Additionally, sperm have a high energy metabolism to sustain their journey to the egg.
Fertilization occurs when a sperm and egg unite.
The egg must break the zonato do thatProteins of the sperm surface must hook up precisely to the set of proteins in the egg surface. If they match the egg is held fast.Next, it sheds it outer coating releasing enzymes that dissolve a hole in the zona to allow the sperm to push its way through.At its final pass, the sperm still does not trust its way alone to the the egg its self, rather the membrane of the two cells fuse, and the egg draws the entire content of the sperm inside.

The size of egg is larger than sperm because the the sperm enters inside the egg and egg has to accommodate the sperm. And egg contains fats and nutrients in order to feed zygote in case of pregnancy.
The cervix acts as a door between the vagina and the uterus. It opens and thins during ovulation to allow sperm to enter the uterus and potentially fertilize an egg.
The change in the egg's covering is due to a process called the zona reaction, which is triggered by the entry of the sperm into the egg. This reaction helps prevent other sperm from entering the egg, ensuring that only one sperm fertilizes the egg.
