Low zinc levels affect fertility: Women lacking in the mineral will struggle to conceive for up to three months, examine discoveries

A study from Pennsylvania State University found that zinc inadequacies can cause infertility by hindering egg development

More than 80 percent of women in the US don’t get enough zinc, known as’ the fertility mineral’

More than one in ten couples in the US struggle to conceive

Women who want to get pregnant should have their zinc levels tested three months in advance to see inadequacies that could cause fertility problems, new research suggests.

Infertility is on the rise in the US with more than one in ten couples in the US experiencing problems with conceiving.

A growing body of research suggests that girls take more supplements including zinc, known as’ the fertility mineral’ because of the large role it plays in regulating the reproductive system.

A study from Pennsylvania State University examined how low levels of zinc affect the often-overlooked initial stages of egg developing, exposing that the harmful effects begin months earlier than previously thought.

Fertility research has exploded in recent years as more couples open up about their struggles to conceive and search for a solution.

One specific area of research that’s received a lot of attention is how micronutrients in the ovaries influence the developing, viability and quality of egg cells.

Zinc is commonly thought of as the most important point of those micronutrients.

More than 80 percent of women in the US have zinc deficiencies.

The mineral assistances in regulation of hormones, cell division during the egg development process and preserving a health environment within the ovaries.

The ovary is made up of about one million structures called follicles, which consist of one egg cell supported by layers of somatic cells.

Each month several follicles begin to matured, but typically one will be released in ovulation and have the chance to be fertilized.

Most of the current surveys available focus on different groups that begin to mature each month, known as the antral stage, which ends at ovulation.

In the study published Tuesday the researchers took a more novel approach and looked at the pre-antral stage, which refers to the period before the antral stage when follicles are still growing.

The pre-antral stage begins 90 days before an egg could be ovulated.

‘Previous analyses showed that zinc levels are critical in the antral follicle, but no one had tested the effect of zinc inadequacy on preantral follicle growth ,’ said lead writer James Hester, a graduate student in Integrative and Biomedical Physiology at Pennsylvania State University .

The researchers collected preantral follicles from mice and ripened them in two different environments that mimicked that of the ovary during the maturation process, one with normal levels of zinc and one with insufficient levels.

The most striking finding was that insufficient levels of zinc impaired the egg cell’s ability to properly divide, a necessary and appropriate measures before successful fertilization can occur. This flaw persisted even after more zinc was introduced to the environment.

The zinc-deficient surrounding was also found to disrupt follicle cell growth, resulting in smaller eggs and fewer somatic cells, which are needed to support the egg.

Overall the findings revealed that low levels of zinc impeded the body’s ability to produce eggs that would be able to become fertilized.

They also indicate that the harmful effects of zinc inadequacy began much earlier than was previously thought, and were difficult to reverse.

Hester said these findings have wider implications for people employing expensive and invasive in-vitro fertilization.

‘Interestingly, the[ eggs] commonly used for IVF are collected from antral follicles, so any consequences from preantral developing have already occurred ,’ he said.
