What are some of the Key Blood Tests for Fertility?

March 27, 2024

Getting your blood tests done is a very important part of your fertility journey. Your blood holds important clues about your health, your body’s function, and also your fertility. Here at NSA, we go beyond the conventional “normal” ranges provided by mainstream medicine. There is an important difference between blood test result that are in the “normal range”, versus results that are in the “optimal range” for fertility. So we interpret your test results through the lens of optimal health, especially for those on the path to parenthood. In this blog, we look at a few key blood tests to pay close attention to.  

 

Key Blood Test 1: Iron 

 

Blood_Test_IronIron is often overlooked but it plays an important role, particularly in fertility and pregnancy. For women, iron deficiency is commonly due to monthly blood loss during menstruation. During pregnancy, the demand for iron skyrockets to support the growing foetus and the expansion of the mother’s blood volume.

When iron levels are low, your body prioritises supplying blood to essential organs like the brain and heart. This leaves the blood supply to reproductive organs at the bottom of the list which could cause problems with fertility.

In our clinic, we frequently encounter patients with low ferritin levels (ferritin is the stored iron). This may require an iron supplement or even an iron infusion. It is however important to note that ferritin levels can rise in response to inflammation or infection. Therefore, by merely testing ferritin levels we may overlook iron deficiency.

It is always important to get a comprehensive iron study done. This includes an iron and transferrin level, the iron saturation, and a ferritin level.  This is essential for a thorough understanding of your iron status and your fertility.

 

Key Blood Test 2: Vitamin D

 

Vitamin D is often recognised as an immunity booster but it also plays an important role in fertility. It is involved in hormonal regulation and it influences the production of oestrogen and testosterone. These hormones are essential for the development of eggs and sperm.

A 2017 study revealed that women with lower levels of vitamin D may face challenge in conceiving [1]. Furthermore, research has provided reassuring evidence regarding the safety of vitamin D supplementation during pregnancy. A study done in 2011 demonstrated the safety and effectiveness of pregnant women taking up to 4000iu of vitamin D during pregnancy [2].  

Even though western medicine regards a level of 50 nmol/l or above sufficient, a level of around 100 nmol/l is a more optimal level for fertility from our point of view.

While high cholesterol levels can disrupt hormonal balance and affect fertility, having excessively low cholesterol levels can also pose risk.

Cholesterol serves as the building blocks for sex hormones such as oestrogen, progesterone, and testosterone. Maintaining an optimal cholesterol level is crucial for hormonal balance and reproductive health.
