I assume that would be ovulation and ejaculation. There can't be fertilization without there being an egg to fertilize. Same thing goes if there's nothing to fertilize said egg.
If you're talking more specifically, a sperm needs to match the protein receptors on the surface of the egg, allowing the sperm to burrow through the protective jelly-like coating of the egg for the release of the head while the jelly-like coating hardens to prevent polyspermy.

What are the steps of fertilization in flowering plants?
Fertilization in plants is achieved by union of male gamete with an egg nucleus. The first step in fertilization is formation of male and female gametes, Second step is transfer of male gametes containing pollen to stigma of female reproductive organ by pollination. The third step is germination of pollen grain for movement of male gamete to the vicinity of female gamete. The fourth step is the union of the nucleus of male gamete with egg nucleus in the embryo sac. The fourth step of fertilization in angiosperms is the act of double fertilization. During this process one of the two gametes released by a pollen tube fuses with secondary nucleus. The secondary nucleus is formed by fusion of two nuclei of embryo sac. Thus double fertilization is also called triple fusion.
What is a developing human known as during the first eight weeks after fertilization?
A developing human during the first eight weeks after fertilization is known as an embryo.
Fertilization of an egg cells by pollen from different plant?
When pollen is transferred from one plant to fertilize the egg cell of a different plant, it results in cross-fertilization. This process increases genetic diversity and leads to the formation of seeds with different traits. Cross-fertilization can occur through various mechanisms such as wind, insects, birds, or other animals.
Is the first step of the nitrogen cycle?
The first step of the nitrogen cycle is nitrogen fixation.
What process characterizes a sexual reproduction?
Fertilization
What is the first stage of fertilization?
embryo
What is formed first after fertilization?
zygote
What purpose does fertilization serve?
The purpose of fertilization is the first step in the reproduction of new offspring, which contributes to the longevity of different species, so that they do not become extinct.i.e. human fertilization occurs when a haploid sperm cell & haploid secondary oocyte produce a diploid nucleus

What is the first step of a project?
planning is your first step.
What comes first fertilization or ovulation?
Ovulation has to happen first before fertilization can take place. Otherwise, the egg would still be in the ovary and the sperm wouldn't be able to reach it.
Which process takes place first in the development of a human being?
The very first is sperm (fertilization)... The second first, is cell division, The third first, is the tail of the sperm begans to form the Septums of the heart and when the heart is completed and begins to beat, the first is a living organism.

Can fertilization take place without pollination?
No, fertilization in plants typically occurs after pollination. Pollination is the transfer of pollen from the male reproductive organ to the female reproductive organ of the same or a different plant, leading to the eventual fertilization of the ovule. Therefore, pollination is a necessary step for fertilization to occur in most plants.
What is the first step for the scientifc method?
The first step is to identify the problem
