IVF and Reproductive Health

Assisted reproduction is the umbrella term for the techniques that help conception when it has not happened naturally. IVF is the central one: eggs are matured with hormone medication, collected from the ovaries, fertilised with sperm in the laboratory, grown into embryos and then transferred to the womb. Where the difficulty lies on the male side, a single healthy sperm can be injected directly into each egg, a method called intracytoplasmic sperm injection or ICSI. When no sperm appears in the ejaculate, it can sometimes be recovered directly from the testis through a small procedure. Eggs, sperm and embryos can also be frozen and stored for later use, and embryos can be tested for inherited conditions before transfer. IVF is usually considered when a couple has not conceived after about a year of regular unprotected attempts, or sooner when there is a clear reason such as severe male infertility, blocked tubes or advancing age.

Fertility care addresses causes that can sit with either partner, and often both. On the female side these include difficulty releasing eggs, as in polycystic ovary syndrome, blocked or damaged fallopian tubes, endometriosis, a reduced ovarian reserve with advancing age, and structural problems of the womb such as fibroids, polyps or adhesions. On the male side they include a low sperm count, poor movement or shape of sperm, and the complete absence of sperm in the ejaculate. Recurrent miscarriage, where pregnancies are lost repeatedly, is investigated and managed as its own pathway, sometimes with embryo genetic testing. Many couples have no single identifiable cause, described as unexplained infertility, and still benefit from treatment. Fertility preservation, freezing eggs or sperm before cancer treatment or for personal reasons, is a growing part of the field.

A treatment cycle usually begins with hormone injections that encourage several eggs to mature at once, monitored by ultrasound and blood tests. A final trigger injection completes maturation, and the eggs are collected in a short procedure through the vaginal wall under light sedation. In the laboratory the eggs are fertilised, either by mixing them with prepared sperm or, more often, by injecting one sperm into each egg. The embryos are grown for several days, sometimes to the blastocyst stage, and the most suitable one is placed into the womb in a quick, painless transfer. Supportive hormone medication follows, and a pregnancy blood test is done about two weeks later. Spare good quality embryos can be frozen for a future attempt. When needed, minor surgery on the womb, such as hysteroscopy to remove a polyp, or surgical sperm retrieval for the man, is carried out before the main cycle.

Planning a cycle rests on a careful assessment of both partners. For the woman this includes hormone blood tests, an ultrasound count of the resting follicles to estimate ovarian reserve, and imaging or hysteroscopy to check that the womb cavity and tubes are healthy. For the man a semen analysis measures the number, movement and shape of sperm, with hormone and genetic tests where the count is very low. Modern embryology laboratories use time lapse incubators that photograph embryos continuously so they are disturbed as little as possible, and preimplantation genetic testing can screen embryos for chromosome problems or specific inherited diseases such as thalassaemia or muscular conditions before transfer. These tools help match the treatment to the individual and improve the chance of a healthy single pregnancy.

For people who travel, a cycle is usually mapped out in advance so that the time abroad is as short as possible. After a remote consultation and the first tests, much of the early hormone stimulation can sometimes begin at home under guidance, with the visit timed around egg collection, fertilisation and transfer. A typical stay for the active part of a cycle is around two to three weeks, though plans vary with the protocol and the laboratory results. The male partner usually needs to be present to provide a sperm sample around the time of egg collection, although sperm can sometimes be frozen in advance if travel is difficult. Many patients choose a frozen embryo transfer in a later, shorter visit, which separates the demanding stimulation phase from the transfer and can suit a travel schedule well. Interpreter and international patient support is widely available to coordinate appointments, medication and the emotional side of treatment.
