A randomized study in 2013 came to the result that the rates of intrauterine pregnancy two years after treatment of ectopic pregnancy are approximately 64% with radical surgery, 67% with medication, and 70% with conservative surgery. In comparison, the cumulative pregnancy rate of women under 40 years of age in the general population over two years is over 90%. Hydrosalpinx is the most frequent. This happens when there is a presence of fluid on the tubes. We have some ways to test it: Hysterosalphingography, in which we can see both the uterus (Hystero) and the tubes. Hysterosonosalphingography, in which we see only the uterus. This tests are used to check if the tubes are permeable or if   there is any obstacle in the path to the uterus. We have to introduce a liquid contrast via vagina, and we check its path via x-ray. If the tube is blocked, the contrast liquid will be stopped in the tubes, but if its not blocked, it will end in the abdominal cavity. The flow of this contrast needs peristaltic movements. This blockage can be produced by sexually transmitted diseases, previous surgery, peritonitis or endometriosis. Uterine factors
Uterine malformations
Uterine fibroids
Ashermans syndrome
Implantation failure without any known primary cause. It results in negative pregnancy test despite having performed e.g. embryo transfer.Previously, a bicornuate uterus was thought to be associated with infertility, but recent studies have not confirmed such an association. Cervical factors
Cervical stenosis
Antisperm antibodies
Non-receptive cervical mucus

Vaginal factors
Vaginismus
Vaginal obstruction

Interrupted meiosis
Meiosis.
Proper nutrition in early life is also a major factor for later fertility.A study in the US indicated that approximately 20% of infertile women had a past or current eating disorder, which is five times higher than the general lifetime prevalence rate.A review from 2010 concluded that overweight and obese subfertile women have a reduced probability of successful fertility treatment and their pregnancies are associated with more complications and higher costs. In hypothetical groups of 1,000 women undergoing fertility care, the study counted approximately 800 live births for normal weight and 690 live births for overweight and obese anovulatory women. For ovulatory women, the study counted approximately 700 live births for normal weight, 550 live births for overweight and 530 live births for obese women. The increase in cost per live birth in anovulatory overweight and obese women were, respectively, 54 and 100% higher than their normal weight counterparts, for ovulatory women they were 44 and 70% higher, respectively. Radiation
Exposure to radiation poses a high risk of infertility, depending on the frequency, power, and exposure duration. Radiotherapy is reported to cause infertility,. the amount of radiation absorbed by the ovaries will determine if she becomes infertile. High doses can destroy some or all of the eggs in the ovaries and might cause infertility or early menopause. Chemotherapy
Chemotherapy poses a high risk of infertility. Chemotherapies with high risk of infertility include procarbazine and other alkylating drugs such as cyclophosphamide, ifosfamide, busulfan, melphalan, chlorambucil and chlormethine.
