For women under 35, there is around a 25% chance of becoming pregnant when the woman is ovulating. After 35, women’s reproductive potential decreases and after the age of 40 the chances of becoming pregnant naturally fall to 10% during ovulation.

To diagnose infertility, the IVI clinic will obtain a full medical history and complete a physical examination of both members of the couple. For women, the basic tests are a basal hormone study, an ultrasound scan and a hysterosalpingography (an x-ray to investigate the uterine cavity and fallopian tubes). The range of tests may be extended, depending on the patient. For men, there is an assessment of semen quality via a seminogram test.

What is the difference between primary infertility and secondary infertility?

We talk about causes of primary infertility when a couple falls pregnant spontaneously on two or more occasions, but it is impossible for them to carry the pregnancy to full term.

How can you know which days you are ovulating?

Ovulation, or a woman’s fertile period, occurs around halfway through each cycle, on roughly the fourteenth day in a supposed 28-day cycle. It has been proven that 24 hours after ovulation there is a rise in base body temperature of between 0.4 and 0.6 degrees. This is the signal on which the control method is based, marking the days on which ovulation occurs.

How often should a couple have sex in order to achieve pregnancy?

Once the ovum (egg) has left the ovary it survives approximately 48 hours and it is only during this time that it can be fertilised by spermatozoa, which maintain their capacity for fertilisation for a maximum of 72 hours. In any case, it is better not to be obsessed with monitoring ovulation, because anxiety about pregnancy is counterproductive to getting pregnant and it can even damage a couple’s relationship. Nevertheless, the probability of a spontaneous pregnancy after one year of trying decreases greatly, even with careful scheduling of sexual relations.

Does age affect fertility?

Many women are choosing to have children later in life, but fertility decreases over time. Female fertility decreases more rapidly after 35 and male fertility gradually decreases after the age of 40. Men and women are most fertile in their early 20’s.

Is there an age limit for having fertility treatment?

There is no legal limit that prevents a couple from having fertility treatment. Outcomes depend on the circumstances of each couple, on their health and physical condition. For women, 50 is a reasonable limit beyond which fertility treatment is not typically recommended.
