Infertility affects thousands of couples around the world and is a source of emotional and physical strain. Knowing what treatments are available for fertility and their success rates can aid a couple in making up their minds regarding their parenthood. The blog lists major fertility treatments, their methodologies, and associated success rates in general with special reference to the Indian scenario.
Understanding Infertility
Infertility is defined as the inability to conceive after one year of unprotected intercourse. It affects both the male and female population in equal numbers, each having a wide array of underlying conditions such as hormonal abnormalities, structural problems, or idiopathic factors.
Human Fertility Treatment Options
1. Medication:
The most common approach to treating infertility is the use of medications. The medications are mainly involved in regulating and stimulating ovulation in women. Among the common fertility drugs are the following:
Clomiphene Citrate:
The drug stimulates ovulation by increasing the production.
Gonadotropins (FSH and hCG):
They act by direct stimulation of the ovary to form eggs.
Letrozole:
While primarily indicated for breast cancer, it can stimulate ovulation.
Although these medications are effective, they come with the risk of giving birth to multiple pregnancies and ovarian hyperstimulation syndrome (OHSS).
2. Surgery:
Surgical procedures can be used to correct structural abnormalities in the reproductive organs. Some of the surgeries are:
Tubal Surgeries:
Unblock or repair any blockages or damage in the fallopian tubes.
Laparoscopic or hysteroscopic:
Surgeries for removal of uterine fibroids, polyps.
These procedures are not done as often because of the high success rates of less invasive treatments, but they become essential in some cases.
3. Intrauterine Insemination (IUI)
In IUI, this method places sperm into a woman’s uterus to coincide with ovulation. Since the number of sperm that reach the fallopian tubes is increased, fertilization chances are also improved. The procedure is quite simple, with only minimal risks of rare infections and mild pain.
4. In Vitro Fertilization (IVF)
IVF is one of the best-known fertility treatments. The process involves the fertilization of an egg by sperm outside the body and then the implantation of the embryo in the uterus. The steps include:
Ovarian Stimulation:
This is the use of medications to produce several eggs.
Egg Retrieval:
Collection of eggs from the ovaries.
Fertilization:
Egg and sperm are mixed together or ICSI (Intracytoplasmic sperm injection) in a laboratory.
Embryo Transfer:
Placing embryos into the uterus.
The range of the in vitro fertilization success rates varies with the major condition set out as a parameter to the life conditions in general: age and health. Success rates with each cycle of in vitro fertilization can be as high as 30 – 35% for women under 30 years but steadily decline with age.
5. Intracytoplasmic Sperm Injection (ICSI)
ICSI is used to tackle severe male infertility. Most often it is performed along with in vitro fertilization; however, it also has success rates by itself. A single sperm is directly injected into an egg. This method has proved especially useful in the case of serious problems with sperm quality or quantity.
6. Donor Eggs, Sperm, or Embryos
Couples for whom one or both partners have infertility issues may also be using donor eggs, sperm, or embryos. This involves third-party genetic material to achieve pregnancy.
7. Surrogacy
Surrogacy is a case of another woman carrying a pregnancy for the intended parents. It is considered in cases where the intended mother cannot take a pregnancy to term due to medical reasons.
Success Rates
Success rates of treatment differ by many variables such as age, cause of infertility, and specific treatment protocol used:
Medication varies, and ovulation induction reportedly achieves a success rate of 40-50% per cycle.
Surgery:
This varies greatly depending on the type and extent of surgery but can be very effective for some conditions.
IUI:
Success rates range between 10% and 20%.
IVF:
IVF is successful in up to 45% of cases in women who are under 30 years of age.
ICSI:
Like in vitro fertilization, but really good for male infertility.
Programs for Egg/Sperm Donors:
Usually show a higher success because of the quality of the egg or sperm through donors.
Surrogacy:
Success, especially when done by IVF.
Conclusion
While infertility is hard to face, many couples can reach for hope from among the treatments available. Knowledge of treatment types and their success rates will help lead couples to decide what is best for them. Consulting with a specialist in fertility is key in personalizing treatment according to individual needs and circumstances.
