When male and female gamete fuse together fertilization occur. In human it takes place in the fallopian tube. The zygote formed then divides itself and implants in the uterus/ womb. Where it is richly supplied with blood vessels.

Answer:
In human beings, one egg is released from either of the ovaries once in a month. The egg is transferred to the fallopian tubefrom the ovaries. Sperms swim up to the fallopian tube. Only one sperm is able to penetrate the egg. That is how fertilization takes place.
A menstrual cycle is composed of about 28 days. This means only one egg is available for fertilization in one menstrual cycle. Hence, it can be said that fertilization can occur only once in a month.
