The process is know as Meiosis II, the second stage in the process of cell division for sexual reproduction.
Spermatogenisis produces four gametes while oogenesis produces only one. Oogenesis produces one egg and three polar bodies (that immediately die off). Spermatogenisis produces four sperm that are al equally complex. The egg is the major part of the potential fertilized cell and it takes a lot of energy to make (think about it, all it needs to start dividing is a few extra chromosomes) and therefore most of the process's energy goes to the egg.
It would take cell divisions for one original cell to produce
Oogenesis is the formation of the ovum, and spermatogenesis is the formation of the sperm. These two processes are similar as they are both formed by meiosis, (reduction division). Meiosis is the process of cell division where one mother cell will create four daughter cells with half the amount of genetic information. Or in other words, oogenesis and spermatogenesis are creating gametes.

spermatogenesis produces 4 sperm cells and oogenisis produces one ovum. Both have 23 chromosomes each

It would take cell divisions for one original cell to produce
In oogenesis after the first meiotic division one egg and one tiny cell are created. In Meiosis II the egg and three small cells are created. The three small cells are thrown away and the egg undergoes fertilization. In spermatogenesis after meiosis II four working sperms are ready to be used. There is only one usable cell created in oogenesis while in spermatogenesis four cells are created. the end result of oogenesis is only one viable cell while in sprematogenesis there are four.
In a typical somatic cell, mitosis produces one diploid "daughter" cell from one diploid parent cell. In a gametic cell, meiosis produces 4 haploid "daughter" cells from one diploid parent cell.
Meiosis produces 4 cells from one mother cell. Each of these four cells has half the genetic material as the original.

True. Your question is self-explanatory. Multiplying any number by one produces the original number.
1 egg from the original cell
One cell divides into two in a process called mitosis. Mitosis produces two genetically identical “daughter” cells from a single parent cell. Another type of cell division, meiosis, creates four daughter cells that are genetically distinct from one another and from the original parent cell.
The formation of male gametes or sperm cells is called spermatogenesis. This is a form a meiosis, in which four daughter cells are formed. The process takes places in the male reproductive organs, the testes. The female counterpart to this is called oogenesis, which produces one usable daughter cells, an oocyte or egg cell, (and three discarded cells called polar bodies) this process occurs in the ovaries.
