ABSTRACT
Objective: The aim of the present study was to examine
the effect of assisted hatching (AH) using zona-drilling
techniques on pregnancy rate, miscarriage rate and
multiple pregnancy rates, in a selected group of patients.
Design: Aretrospective study.
Setting: The Lister Hospital Assisted Conception Unit.
Patients: Between July 1996 and December 2000, 141
patients were treated with AH prior to embryo transfer.
The effect of AH was compared to a control group of 456
patients who underwent embryo transfer without AH
during the same time period.
Intervention: Assisted Hatching.
Main outcome: Pregnancy rates, live births, single and

multiple pregnancies and miscarriage rates.
. The pregnancy rates, live birth rates, the incidence
of single and multiple pregnancies and miscarriage rates
were comparable in both groups.
Conclusion: These results suggest that assisted hatching
is not detrimental to health and may improve the
outcome in patients with poor prognostic factors,
resulting in rates of pregnancy comparable to that of the
ovarian hyperstimulation syndrome
Abstract
Objective:
To present our experience in 48 coasted
patients and how they performed in terms of the
number of eggs collected, numbers of embryos
available for embryo transfer after In-Vitro
Fertilization, pregnant and on going pregnancy
rate.
Methods:
The study was conducted in Lister Hospital,
London, United Kingdom. For the purpose of
the study we selected coasted cycles in patients
who were less than 38 years of age (n=48 cycle
48 patients). A control group of cycles
consisted of all cycles during the same period
in patients less than 38 years of age, who were
not coasted because they did not fulfil the at
risk criteria but yet we collected 20 oocytes or
more (n=115 cycles, 113 patients).
