Not is a normal production of thyroid hormones essential for successful pregnancy, deficiency of these hormones may lead to infertility in both men and women.
Thyroid secretion is vital for quality and quantity of sperm production, and also for fertilization of egg. If there an insufficient production of thyroid hormones, the sperm count may decrease. Also, the sperms lifespan is shortened. This means, if your partner has hypothyroidism, your prospects of becoming pregnant is reduced to a certain extent.
In women, the effects of hypothyroidism on pregnancy as well as fertility are even more complicated. An underactive thyroid gland can caused decreased libido, irregular menstrual cycle, and inability to ovulate. In pregnant women, this condition can lead to preeclampsia, miscarriage, and premature childbirth.
These are all very serious consequences and as such, timely monitoring and treatment is a must for hypothyroidism. Decreased sexual drive, menstrual cycle irregularity, and ovulation problems drastically reduced the chances of women becoming pregnant.
Also, in pregnant women with thyroid dysfunction, there is an insufficient production of progesterone, a hormone which prepares and maintains the uterus for and during pregnancy.
Insufficient level of progesterone may lead to prevention of the embryo from attaching. Also, the luteal phase in woman is shortened in women with hypothyroidism and hence there is a risk of miscarriage involved.
Considering the negative effects of hypothyroidism on fertility and pregnancy, you should always look out for its symptoms so that timely actions can be taken. Symptoms of hypothyroidism include unexplained weight gain, fatigue, irritability, depression, quicker heart beat, irregular menstrual cycles, dry skin, and sensitivity to cold.
Even if you have a few of these signs, consult with your physician. A blood test will be advised to see if your thyroid gland has any dysfunction.
Thankfully hypothyroidism treatment is rather simple. Thyroid hormone replacement therapy is recommended for patients with borderline cases. In other cases, where this therapy may not be effective, oral thyroid hormone supplements are given to make up the deficiency.
