An option that is available for any couples is IVF (in vitro fertilization) which harvests the eggs and sperm and places them in the woman's womb. An option for couples containing two women is a sperm bank, and an option for couples containing two men is surrogacy, which is where another person carries the baby for them.
All the other options seem like good reasons but are not as important as improving your overall skills (from my perspective at least). Hope this helps!
