Advantages-

-No threat to custody no matter what happens in your romantic life, your relationship with any woman will not jeopardize your children

-Ability to choose gametes from healthy young high quality women that you may be unable to get to commit to having children at such a young age. In the future one will be able to create eggs and sperm from his own skin cells so you won't even need to pay some random woman for this.

-Ability to choose sex, and in the future potentially other genetic characteristics at your whim. Can also mean the difference between the preservation or death of recessive traits in your genetic line.

-A way for those who married outside their race to make a positive contribution to their people

-Can implant 2-4 embryos in one go which isn't a guarantee the natural route, can achieve your goals with repopulation in one fell swoop

-Children raised in single father households show none of the issues that those in single mother households do and have similar outcomes to those in traditional nuclear families.

Disadvantages-

-Costs 6 figures in total for a pregnancy including the egg donor, surrogate, hospital fees, etc, though the cost per child can be mitigated by implanting more embryos at once.

-Difficult to control diet and other epigenetic factors for both the egg donor and the surrogate which can have knock-on effects. In the book Deep Nutrition it's described how the diet and environment of the mother can determine the hormonal environment and the facial aesthetics of the child

-More expenses would be needed to take care of child rearing and acquiring breastmilk than would be needed if you had a stay at home mother, this almost seems practical only if you have passive income/work at home or you have parents willing to help out (preferably both).

-Some would say the lack of mother in the child's life is unnatural and cruel

-For those who are religious, this is reproduction outside of marriage. Though no intercourse is involved the child is still conceived outside of a union recognized by God.

Bottom line

With current technology any man can have 3-4 kids for a relatively small low 6 figure sum. For the purposes of this community this means the survival of the White race is no longer contingent on the rehabilitation of women, and can continue in the future as long as even one White person exists and has the cash. Do what you will with this information.
