Retroverted uterus is a normal anatomical variant and should not interfere with your ability to conceive. Occasionally a sharply tilted (acutely retroverted) uterus that could be caused by endometriosis can make it challenging for the sperm to reach the egg. Polycystic ovary syndrome (PCOS) is associated with irregular ovulation which can contribute to infertility.
Approximately one third to half of women with endometriosis have difficulty conceiving. Endometriosis may also affect fertility in less direct ways such as damage to eggs, embryos.
Adenomyosis can also affect pregnancy outcome, and hyperthyroidism must be treated before pregnancy.
You seem to have a few conditions which may affect your chances of conceiving. I recommend that you seek a consultation with a specialist to address your concerns.
