The Andalusian Registry of Pregnancies in patients with multiple sclerosis is the largest Spanish registry on multiple sclerosis (MS) and family planning. For the first time, it includes information on the fertility of men with MS. The influence of the use of a disease-modifying treatment (DMT) on the health of the foetus/newborn and the impact of breastfeeding on MS are also analysed.
This is a multicentre, prospective and observational study. Recruitment of patients took place between December 2018 and December 2020. Women were followed up for one year after delivery. Altogether 100 women and 16 men were included, with a total of 103 newborn infants.
The annualised relapse rate of the women with MS decreased significantly during pregnancy (from 0.23 to 0.065). A total of 11.2% of patients resorted to assisted reproductive techniques in order to conceive a child. No association was found between the use of a DMT at conception and/or pregnancy and the risk of miscarriage, prematurity or low birth weight. Over half the women with MS (54.2%) chose to breastfeed (26.7% of them while on a DMT).
MS does not affect the fertility of men. Neither does the use of a DMT at the time of conception affect their fertility or their children's health. Assisted reproductive techniques did not have a negative impact on the course of MS. Breastfeeding is a common practice among women with MS and there is no evidence of positive or negative effects on disease progression.
