In vitro fertilization. The Jamaican experience

In June 2000, twenty-eight infertile couples were treated by in vitro fertilization and embryo transfer at our initial assisted reproduction programme carried out in conjunction with Midland Fertility Services, Aldridge, Birmingham, England. A pre-requisite for treatment was that on day 3 of the menstrual cycle the levels of follicle stimulating hormone (FSH) and oestradiol (E2) should be < 10 i mu/l and < 100 pg/ml respectively in the female partner. The ages of the women ranged from 26 to 42 years with a mean age of 35.5 years. Down regulation was carried out by using buserelin acetate 0.5 microgram subcutaneously from day 21 of the cycle for 21 days. This process was completed when the ovaries and pituitary gland were quiescent and the endometrial thickness < 4 mm in diameter. On completion of down regulation the gonadotrophin hormone, pergonal (dosage of 150-450 units) was used for ovarian hyperstimulation. A total of 294 oocytes (mean of 10.5, range 2-45) were retrieved of which 138 were fertilized (mean of 4.9, range of 0-28). Twenty-four patients each received a mean of two embryos. Five patients (20.8) had positive pregnancy tests. Three patients (0.1) developed ovarian hyperstimulation syndrome (OHSS), one had the severe, and two, the mild form of the syndrome. All three cases were treated successfully. The success at the initial IVF controlled ovarian hyperstimulation augers well for the future of infertile couples seeking treatment at the Fertility Management Unit, The University of the West Indies, Jamaica.

A case of severe ovarian hyperstimulation syndrome

Ovarian hyperstimulation syndrome (OHSS) is the serious physiological complication in patients undergoing controlled ovarian hyperstimulation. In a recently concluded treatment cycle of 28 women at the fertility management unit at the University Hospital of the West Indies, one patient developed symptoms and signs of severe ovarian hyperstimulation syndrome. Administration of human chorionic gonadotrophin (HCG) had a direct influence on the development of the syndrome. High risk cases, such as young patients, particularly those with polycystic ovaries or those with serum oestradiol levels >10,000 pmol/l and a large number of follicles, must be identified. Preventative measures include cylce cancellation, reduction of HCG dosage, egg retrieval and cryopreservation of embryos rather than embryo transfer.(Au)

In vitro Fertilization: the Jamacian experience

In June 2000, twenty-eight infertile couples were treated by vitro fertilization and embryo transfer at our initial assisted reproduction programme carried out in conjunction with Midland Fertility Services, Aldridge, Birmingham, England. A pre-requisite for treatment was that on day 3 of the menstrual cycle the levels of follicle stimulating hormone (FSH) and oestradiol (E2) should be <10iu/l and <100pg/ml respectively in the female partner. The ages of the women ranged from 26 to 42 years with a mean age of 35.5 years. Down regulation was carried out by using buserelin acetate 0.5 ug subcutaneously from day 21 of the cycle for 21 days. This process was completed when the ovaries and pituitary gland were quiescent and the endometrial thickness <4 mm in diameter. On completion of down regulation the gonadotrophin hormone, pergonal (dosage of 150-450 units) was used for ovarian hyperstimulation. A total of 294 oocytes (mean of 10.5, range 2-45) were retrieved of which 138 were fertilized (mean of 4.9, range of 0-28). Twenty-four patients each received a mean of two embryos. Five patients (20.8 percent) had positive pregnancy tests. Three patients (0.1 percent) developed ovarian hyperstimulation syndrome (OHSS), one had the severe, and two, the mild form of the syndrome. All three cases were treated successfully.
