Successful pregnancy outcomes are improved when hypothyroidism is treated. [129] Levothyroxine treatment may be considered at lower TSH levels in pregnancy than in standard treatment. [15] Liothyronine does not cross the fetal blood-brain barrier, so liothyronine (T 3) only or liothyronine + levothyroxine (T 3 + T 4) therapy is not indicated in ...
Levothyroxine, also known as L-thyroxine, is a synthetic form of the thyroid hormone thyroxine (T 4). [5] [8] It is used to treat thyroid hormone deficiency (hypothyroidism), including a severe form known as myxedema coma. [5]
Also in normal pregnancies, adequate levels of maternal thyroid hormone are vital in order to ensure thyroid hormone availability for the foetus and its developing brain. [88] Congenital hypothyroidism occurs in every 1 in 1600–3400 newborns with most being born asymptomatic and developing related symptoms weeks after birth.

So wherever a normal distribution could be used for a hypothesis test, a chi-squared distribution could be used. Suppose that Z {\displaystyle Z} is a random variable sampled from the standard normal distribution, where the mean is 0 {\displaystyle 0} and the variance is 1 {\displaystyle 1} : Z ∼ N ( 0 , 1 ) {\displaystyle Z\sim N(0,1)} .
The parents of the affected individual are usually genetically normal. [14] The incidence of the syndrome increases with the age of the mother, from less than 0.1% for 20-year-old mothers to 3% for those of age 45. [4] It is believed to occur by chance, with no known behavioral activity or environmental factor that changes the probability. [2]
