5.1 Can fertility be affected in schizophrenia?
“The short answer is: fertility is usually preserved, but several interacting factors can influence it.”
Elena:
Dr. Stein, many families wonder whether schizophrenia affects the ability to have children. Is fertility reduced?
Dr. Stein:
That’s a very important and very common question.
The short answer is: fertility is usually preserved, but several interacting factors can influence it. Even with this information, many people still feel uncertain. “Does this apply to me?” is a common question.
Fertility in people living with schizophrenia is not absent, but it may be lower on average or more variable, depending on individual circumstances.
Elena:
The issue is not impossibility, but variability?
Dr. Stein:
Historically, people with schizophrenia have had lower birth rates, but this is not only due to biological factors. It is also influenced by social and health-related aspects, such as relationship opportunities, overall health, and access to care.
Today, this is changing, as care improves and more people can plan their lives, including having children. But for many, the question still comes with hesitation, not only hope.
What factors can influence fertility?
Elena:
What are the main things that can influence fertility?
Dr. Stein:
There isn’t just one single factor.
In real life, it’s usually a combination of different things that come together, sometimes biological, sometimes related to overall health, and sometimes connected to everyday life.
Elena:
Can you give us a sense of what that looks like?
Dr. Stein:
Of course.
Sometimes it starts with the body’s internal balance. Hormones play an important role in fertility, and one hormone we often look at is prolactin.
When prolactin levels are higher, it can affect things like menstrual cycles in women, or testosterone and sperm production in men.
What’s important to know is that these changes don’t always come only from treatment. They can also be part of how the illness affects the body itself.
Elena:
It’s not always something people can see or immediately notice.
Dr. Stein:
Beyond hormones, there are also very everyday aspects of health that matter.
Things like changes in weight, general physical condition, or habits such as smoking can influence fertility over time. These are not specific to schizophrenia, but they tend to appear more often in this context, which is why we pay attention to them.
Elena:
Is fertility also connected to general well-being?
Dr. Stein:
Yes, it is.
And there is another layer that is just as important.
Fertility is not only about biology. It’s also about life circumstances.
Things like feeling stable in a relationship, having access to care, or simply being able to talk openly about plans all play a role.
In practice, we often see that these elements are closely connected. Sometimes people expect a simple explanation, and it can be frustrating when things are more complex. It’s not just one factor, but how they come together in a person’s life. And that can feel confusing at first, because there isn’t always a single clear answer.
Elena:
When families hear that fertility may be affected, it doesn’t mean that having children is unlikely.
Dr. Stein:
It’s more accurate to say that fertility can be influenced, sometimes in subtle ways, but not removed.
In many cases, these challenges can be understood and addressed. And with the
right support and planning, many people may have children.
