Here's the thing...
If cursed women give birth only to daughters who are also cursed, there is only one solution... Kill them all! Right now! Before any of them escape!
...or at the very least, have them sterilised. Immediately!
Yes, it's a draconian solution... but consider the alternative: Extinction of the entire human species in 65 generations - about 1300 years.
Here's how it would happen:
Let's suppose that we have 200,000,000 humans on earth: 100,000,000 men, 99,995,000 women and 5000 cursed women. Let the rate of population increase be 2.02 surviving adult children per woman. Women are fertile for 1 generation. Men are fertile for 2 generations, and life expectancy averages 2 generations. On average, each male partners with 10 women during their life.
Each generation, the fertile normal women will each produce 1.01 males and 1.01 females, while each generation, the cursed women will each produce 2.02 cursed women.
Hopefully you can see where this is going... unless these cursed women can be distinguished from the normal women, the cursed women will produce more female offspring than the normal women. By Generation 25, there will be more cursed women than uncursed and eventually (at around Generation 31, or 620 years) the cursed women will compete for the proportionally dwindling number of men, to the point where there are literally not enough men to impregnate all the fertile women. Two generations after that, human population will plateau, and from that point, the human population will decline as there are fewer and fewer men born to fewer and fewer uncursed women. By generation 64, the last man and uncursed woman will die... and the cursed women will have at most around a century before they all die - childless, for lack of any male to impregnate them.
I ran the math on an Excel workbook, and while my model may not have been perfect, the undeniable fact is that only women can contribute to population growth, and the cursed women are producing twice as many new women each generation as the normal women - and no men. This will inevitably lead to a growing gender imbalance that will doom the species.
If these cursed women are killed, but just one fertile cursed woman escapes, humanity is still potentially doomed: By Generation 46, cursed women will outnumber the uncursed, by Generation 52, men will be in short supply such that they can't impregnate all the fertile women, and by Generation 86, all the uncursed women and all the men will have died.
As The Nate has pointed out, this assumes perfect mixing, and this is as stated a localised phenomenon at the beginning. However, consider that we are talking about humans, and unless the surviving non-cursed can identify and at the least shun the cursed women, a gender imbalance is going to occur, and as it worsens, at least some of the excess women are going to go looking for men elsewhere... by the time that the gender imbalance grows to the point where some women cannot find a mate locally, there will be over a billion cursed women and only around a hundred million or so uncursed women. You can't tell me that these sexually frustrated women won't scour the whole world in their search for more men... and who is going to stop them?
If we assume that as women come to outnumber men, male fertility and availability will rise, from an average of around 10 per male per lifetime with gender balance, to 5000, based on genetic studies that have shown that Ghengis Khan fathered as many as 2000 children by himself... This will only make things worse. The numbers of cursed women will explode to the point where women will begin to fight wars for access to resources... and men.
If there is no way to identify uncursed women, the only way that this scenario wouldn't turn out to be an extinction-level disaster for humanity is if the cursed women can still concieve sons, but the sons are all stillborn, along with an associated significantly increased risk of death for the cursed mother and any female siblings in-utero with the doomed male fetus. That way, the population of cursed women would be self-limiting.
This all assumes a lack of human intelligence. If uncursed women can be identified, they could be nurtured and supported and encouraged to have as many children as possible, while cursed women could be restricted from bearing children, the more strictly, the better off humanity will be. In order for humanity to survive this, the rate of births of uncursed women must exceed that of the rate of births of cursed women.
A possible strategy could be implementing a strict one-child policy for any woman who cannot show that a relative or ancestor on their maternal line has given birth to a boy, and incentives for uncursed women to have as many children as possible.
This could lead to a rare-male society, where males and breeder females are cherished and protected, males are encouraged to be highly promiscuous and the cursed women are assigned the more dangerous jobs - like fighting wars.
