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.
Fertilization of an egg cells by pollen from different plant?
Self-Pollinationits actually cross pollination
What is the difference between germination and pollination?
Pollination occurs when pollen reaches the pistil (female parts) of the flower. Fertilization occurs when the sperm cells of the flower fuses with the egg. Germination happens when the conditions are right the plant embryo germinates and begins to develop into a young plant. It is the only stage that does not include fertilization. Pollination is the first step fertilization the second and germination the third and final step.
What process characterizes a sexual reproduction?
Fertilization
Is the first step aerobic respiration the first step in anaerobic respiration?
Yes
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 formed first after fertilization?
zygote
What is the first stage of fertilization?
embryo
What is the first stage of development after fertilization?
Zygote
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 first in the development of a human being?
