No, sperm is not considered an antigen at the time of fertilization. Antigens are substances that the immune system recognizes as foreign and can trigger an immune response. Sperm is a normal component of reproduction and does not elicit an immune response during fertilization.
lets check it together with proper time measurement
Fertilization occurs when the sperm cell successfully enters and fuses with the egg cell, resulting in the formation of a zygote with a complete set of chromosomes. This typically happens in the fallopian tube after sexual intercourse or assisted reproduction procedures.
After fertilization the ovary develops into the fruit

The grasshopper's method of fertilization is internal. They undergo both complete and incomplete metamorphosis.
it is completed during the 2nd week of fertilization

Internal fertilization is considered more advantageous than external fertilization because it provides a safer and more controlled environment for the vulnerable eggs and sperm to meet, increasing the chances of successful fertilization. It also allows for the development of specialized structures and behaviors that can enhance reproductive success, such as copulatory organs and courtship rituals. Additionally, internal fertilization helps prevent desiccation of gametes in terrestrial environments and reduces competition from other sperm.
A secondary oocyte will complete meiosis II after fertilization by a sperm cell.
I'm gonna say complete metamorphosis because they undergo internal fertilization the same as humans

In vetro fertilization, not just vetro. A egg is taken from the woman and sperm is injected into it in a lab and then the egg is implanted back into the woman. It may or may not develop.
No, in most fungi, fertilization is not complete after the cells fuse together. Fusion of the cells (plasmogamy) is followed by the fusion of their nuclei (karyogamy) to form a diploid zygote, which then undergoes meiosis to produce haploid spores. This process completes the sexual cycle in most fungi.
the sperm may not alwayse get to the egg
