Other hormonal causes for pregnancy not occurring
Many hormonal problems have an interactive effect. For instance, hypothyroidism (underactive thyroid) is usually associated with elevated prolactin levels, and PCOS with elevated androgen levels. Our specialists will analyse your hormones and provide you with comprehensive feedback about the causes and symptoms.
- Pituitary gland dysfunction/GnRH dysfunction: The pituitary gland (hypophysis) controls the production of the female sex hormones FSH and LH. If the pituitary gland or production of the messenger GnRH in the hypothalamus is impaired, this can affect egg maturation.
- Yellow body deficiency: If the yellow bodies resulting from ovulation produce too little yellow body hormone (progesterone), this makes implantation of an egg in the uterus more difficult and increases the risk of premature miscarriage.
- Elevated prolactin: The hormone prolactin is actually secreted during the lactation period and inhibits the production of FSH and LH so that ovulation will only rarely take place. If there is increased production of prolactin in women who are not currently breastfeeding, this is triggered by dysfunction of the pituitary gland.
- Hypothyroidism: If the thyroid produces too little iodine-containing thyroid hormone, this causes the hypothalamus to increase secretion of the thyroid-stimulating hormone TSH. TSH also stimulates the production of prolactin, and the elevated prolactin levels can lead to a failure to ovulate.
- Premature menopause (POF, premature ovarian failure): If a woman’s ovaries stop working before the age of 40, ovulation will no longer take place.
As a rule, specific hormonal problems can be established through blood analysis. However, please bear in mind that the causes for a failure to become pregnant are very complex – quite often, there are several different reasons. Our doctors align the diagnosis and subsequent treatment methods to your individual case, thereby giving you the best possible chances of a successful pregnancy.
