Misleading thread title

First, the title of your post is somewhat misleading. Technically the minimum age of pregnancy has been established as five years old. The case has been verified, multiple medical professionals have reviewed the data and the mother's and child's conditions postpartum. The newborn was delivered by cesarean section when the LG was five years seven months old after a seven month pregnancy. She was impregnated at five.

Second, " ... the minimum age to birth a child without troubles ... " is far lower than your assumptions. According to cited references by medical professionals, observed both during birth and/or postpartum, multiple LG's have successfully given birth to babies at 8 years of age, some with assistance, and a number unspecified, but many without surgery.

Third ... the youngest LG to pass menarche is cited as 12 months old. Yes ... I typed MONTHS, not years.

The examples provided are statistically unique, but they represent verified occurrences of a successful birth at an unusually young age. It's understood these are exceptions rather than the norm, but they represent the POTENTIAL for a successful birth.

During my research I found something that nearly made me fall out of my chair LMAO:

On the other hand, an older man involved in a sexual and childbearing relationship with a minor may possess developmental or psychosocial deficits that directly reduce his earning potential and other aspects of his attractiveness as a partner.

... and ...

The behavior of adult men who father children with minors is often looked at as "deviant" and representative of problem behavior and psychosocial deficits that may reduce their earning potential and personal stability, making such men less desirable partners to adult women. Adult men who become involved with a minor may be less able to compete successfully with other adult men for women of their own age.

... also ...

However, when we compare older men who father children with minors to their peers who father children with adult women, the men having relationships with adolescents appear to be less desirable partners, since they have comparatively lower earning potential and less established relationships. This probably indicates their lack of success in the market for adult female partners, and might explain why they seek substantially younger partners.

Obviously the researcher is completely unbiased and doesn't intend to impart their opinions in their paper. Yeah ... right!
