What an important question! Ever since Abraham and Sarah had to use a surrogate (the Egyptian woman, Hagar) to give birth, we Jews have had issues with building families and fertility. Even during the time of the Talmud, there were people who understood marriage and fertility as two separate issues.
The first mitzvah given in the Torah is “pru ur’vu – be fruitful and multiply.” This mitzvah precedes any idea of marriage. And although this commandment is understood by Jewish legal decisors (poskim) to be a commandment specifically required of the male (not the woman), it still stands as a separate mitzvah from establishing a family or a marriage.
Also, in a time when the Jewish birth rate is very low, and infertility affects a higher proportion of Jews (perhaps mostly because we so often stay in school longer, putting off the beginning of attempts to give birth until age 28, on the average, when fertility is much reduced from that of 18-year-olds), the urge and desire to bring new Jewish children into the world is not only (only!) a mitzvah, it becomes a high value.
You thus have reason to be interested in being fruitful and multiplying from a number of important Jewish perspectives.
There is, actually, no halachic prohibition of reproducing using technology rather than intercourse. The Talmud records an opinion of Ben Zoma that individuals had been conceived in material left in bathwater. For a society that considered intercourse as one of the methods of contracting marriage, there was often not even a distinction between permitted sex and marriage. Premarital sex, a great bugaboo of Western society, is not even a term that is traditionally expressed in Hebrew or Aramaic, thus demonstrating that it is a foreign concept grafted onto Judaism at some late point to conform with a host society.
That having been said, our sources DO see Judaism as a system that calls for a high level of morality (certainly no less moral than the prevailing social norms). Thus, if the standard thinking in the United States deems “sleeping around (for which there IS a Hebrew term, pritzut)“ to be immoral and unseemly, Jews ought not make that their habit.
Also, Judaism sees the family (with two parents, etc) as being the ideal way to raise a family and to teach values, ideals and mitzvoth from one generation to the next. So although it may not be forbidden halachically to raise a child as a single parent, it is certainly not the desired state.
Although you should definitely find a rabbi with whom to share your concerns and queries, as well as the difficult journey of IVF, I would venture to say to you:
1) pursue parenting. It is one of the greatest challenges we have
2) Don’t, however, give up on marriage. That is generally the best way to raise a child and to live a life of mitzvot.
Don’t give up hope!
