Abstract
- Assisted reproductive technology (IVF-ET) can help couples to overcome problems of infertility.
- IVF-ET is complex and risky.
- Success is not always guaranteed.
- Theoretical concepts and outcomes may differ.
- There are ethical and legal issues to consider.
Introduction
- In vitro fertilization and embryo transfer (IVF-ET)has existed for over 30 years.
- Many million babies have been conceived through IVF-ET.
- IVF-ET technology procedure is developed to aid conception in couples for whom other fertility therapies have been unsuccessful or are not possible (Georgia Reproductive Specialists, 2007).
- IVF-ET is complex with multiple steps.
- Every procedure is risky.
- Procedures result in the insemination and fertilization of oocytes (eggs) in laboratory.
- Embryos are placed in uterus for implantation.
Benefit of IVF-ET
- IVF is an elective medical therapy.
- Couples unable conceive may use IVF-ET to develop pregnancy.
- IVF-ET is a costly therapy.
- IVF-ET needs specialists and elaborate laboratory.
- The risk of congenital baby malformation is yet to be determined.
IVF-EF Procedure
- Several hours after insemination, oocytes are examined for pronuclei or potential fertilization.
- Oocytes are further cultured for additional 24 hours.
- Embryo transfer (ET) into the uterine cavity is conducted.
- The women may go home 2 to 3 hours after the procedure (Georgia Reproductive Specialists, 2007).
Procedures & Risks of IVF-EF
- Superovulation:
- Stimulates egg development to produce several eggs;
- Multiple eggs enhance chances of embryos (fertilized eggs);
- Medications are required for superovulation;
- Medication is administered via injection.
- Risks include:
- Allergic reactions;
- Hyperstimulation of the ovaries;
- failure of the ovaries to respond;
- Cancellation of the treatment cycle due to some adverse outcomes.
- Ovarian Hyperstimulation Syndrome (OHSS):
- High-level of estrogen;
- Excessive fluid retention in the abdomen or chest cavity;
- Thrombosis of arteries or veins may occur and cause stroke;
- Excessive enlargement of ovaries.
- Constant monitoring is required and blood samples needed:
- Pain;
- Skin infection;
- Scarring at the point of extracting blood.
- Use intravaginal ultrasound to monitor follicular development.
- Retrieving the Oocytes (egg retrieval):
- Procedure conducted under transvaginal ultrasound guidance.
- Risks:
- Negative reactions during drug administration and anesthesia;
- Risks from the inserted needle.
- Collecting and Preparing the Sperm:
- Collected through masturbation;
- It is recommended to abstain for two to five days before specimen collection;
- Men may experience stress and failure to produce specimen sperm.
- Insemination of Eggs and Embryo Culture:
- All eggs should be inseminated to enhance the quantity of embryos for transfer;
- Eggs may not be fertilized;
- Progesterone is administered to the woman after transfer, but has side effects, including:
- Vaginal dryness;
- Bloating, breast tenderness;
- Depression, mood swings;
- Delay of menses;
- Some may cause birth defects (Synthetic progesterone-like medications).
- Transferring Embryos to the Uterus:
- Transfer may take place after three days;
- Healthy embryos should be identified;
- Transfer is done through catheter;
- Transfer procedure should aim for the uterus;
- Use medications to increase success rate (DeCherney, 1986; Farquhar, Rishworth, Brown, Nelen, & Marjoribanks, 2013).
- Embryo transfer risks:
- Mild cramping;
- Loss through displacement to the cervix;
- Tubal / ectopic pregnancy due to displacement;
- Minimal risks of bleeding or infection;
- Miscarriage.
Theoretical Concerns & Possible Outcomes
- IVF-ET procedure does not guarantee conception or a successful outcome of pregnancy.
- The known reasons for pregnancy failure:
- Failure of egg development during treatment cycle, premature ovulation, lost egg, pre-existing pelvic condition or technical difficulties;
- Abnormal eggs;
- Insufficient semen;
- Failed fertilization;
- Failed development of embryos;
- Difficulties with embryo transfer;
- External factors, including lab environments (Kovacs, 1999).
Alternatives to IVF-ET
- Couples are unique and thus causes of infertility.
- Consider the following alternatives, which may work or not:
- Intrauterine insemination (IUI);
- Medicinal therapy.
- Consult with physician before opting for IVF-ET.
Other Issues with Assisted Reproduction
- Psychological stress.
- Anxiety.
- Disappointment.
- Time and money commitment are required and thus there is need to reduce costs and ensure success (Nargund, 2009).
- Changes in schedule to meet therapy requirements.
Ethical and Legal Issues
- Written consent form is required from patients.
- Couples must choose how to handle any remaining embryos.
- Potential harm to the embryo (Goldworth, 1999).
- Embryos should be destroyed if the couples are dead.
- Nurses and physicians must observe all legal and ethical concerns (Giddens, 2013).
