ABSTRACT
Tubal factor is still a common cause of female infertility, accounting for more than 40%. The results of tubal reconstructive surgery depend on the condition of tubal wall, the cause of the lesions, the length of follow-up as well as the womans age. The introduction of microsurgical techniques in the treatment of tubo-peritoneal infertility has significantly improved the pregnancy rates as compared to conventional macrosurgery. Laparoscopic surgery is associated with the same reproductive outcome but with less discomfort, shorter hospitalization and quicker resumption to normal activities since the laparotomy incision is avoided. The opportunity to overcome the disturbed tubal function by in vitro fertilization (IVF) raised the question about the treatment strategy in cases of tubal factor infertility. It seems that young patients with extensive destruction of the tubes or older women even with less severe tubal damage should be directed from the beginning to IVF. However, hydrosalpinges may have a negative impact on IVF outcome and salpingectomy prior to IVF seems to improve the chances of conception.

Hysteroscopic endometrial ablation.

ABSTRACT
Ablation of the endometrium for the treatment of dysfunctional
uterine bleeding is a relatively new technique in gynecology. The hysteroscope
allowed this transcervical approach using one of three main modalities
namely Nd:YAG laser, endometrial resection by electrosurgery or rollerball
electrosurgery. The main indication for endometrial ablation is heavy menstrual
loss in the absence of organic disease.
Most surgeons prefer to induce thinning of the endometrium preoperatively
by either GnRH-a or danazol. Amenorrhea or reduced menstrual flow are considered
as successful treatment outcome. This varies in different studies and depends
upon the used ablation technique, power density, time of the device on
tissue, preoperative preparation, age and hormonal status of the patient
population.
Endometrial ablation performed by a competent hysteroscopist
is associated with a high degree of success and a low rate of complications.
It is a reasonable alternative to hysterectomy for the surgical management
of menorrhagia. Proper selection of patients and meticulous technique after
adequate training are mandatory.

Embryo cryopreservation.

ABSTRACT
The first successful pregnancy after transfer of cryopreserved human embryo was described in 1983. The technique has rapidly been incorporated into most in-vitro fertilization (IVF) programs. While the advantages are evident there is little to cause concern regarding its safety. Supernumerary embryos can be frozen and used in subsequent cycles without ovarian hyperstimulation and it is possible to achieve pregnancy rates comparable to those resulting from fresh embryos. Most religiously- influenced ethicits accept that surplus embryos should be kept to assisst the infertile couples in future cycles. Previous studies have reported an increase in obstetric complications in pregnancies resulting from the transfer of frozen embryos. Recent evidence showed that there is no difference when compared with children conceived spontaneously. The incidence of birth defects is not affected by freezing and subsequent development of children appears normal. Nevertheless, emphasis is placed on long-term follow-up of children conceived from frozen embryos to allow further evaluation of growth, development and morbidity.

ABSTRACT
Objective: To investigate the effect of gonadotropic stimulation for IVF on the sonographic evidence of hydrosalpinges.
Design: Retrospective study.
Setting: Governmental IVF Center.
Subjects and Methods: 321 women undergoing gonadotropic stimulation for IVF in 445 consecutive cycles. Those included 30 patients, in 47 cycles, with untreated mono- or bilateral hydrosalpinx. Transvaginal scanning (TVS) was used to perform a basal examination on cycle days 1 to 3, and ,later on, to monitor the response to gonadotropic stimulation.
Results: On basal examination, the sensitivity of TVS in diagnosing hydrosalpinx was 44.7% (21 out of 47 cycles). On repeated scanning, 7 hydrosalpinges, in 6 cycles, were found to be enlarged 2 to 4 days before ovum pick-up (OPU). Another 6 hydrosalpinges, in 6 cycles, were first seen late during late gonadotrophic stimulation and were noted to enlarge on repeated scanning.
Conclusion: On gonadotrophic stimulation for IVF/ET, hydrosalpinges may become evident and/or enlarged on transvaginal sonography (TVS) during late phase of ovulation induction. Balance between the tubal fluid secretion and drainage might explain the presence or the lack of enlargement or sonographic evidence of hydrosalpinges. The awareness of these sonographic findings of hydrosalpinges is important because of its implications on planning for and outcome of IVF/ET therapy.

Department of Obstetrics and Gynecology, Cairo University, Cairo, Egypt.
ABSTRACT
Objective: To report our preliminary experience on the effectiveness of Argon beam coagulation; a new surgical tool in laparoscopic surgery for treatment of pelvic endometriosis.
Design: Prospective study.
Patients and Methods: Forty one patients with pelvic endometriosis were treated laparoscopically using argon beam coagulation (ABC) are presented in this study. Patients were classified into stage I (9 patients), stage II (11 patients), stage III (12 patients) and stage IV (9 patients) [American Fertility Society stages of endometriosis]. At initial laparoscopic surgery endometriotic implants were ablated using ABC. Adnexal and pelvic adhesions were scored and lysed. Patients were followed for a period of at least one year for improvement of pelvic pain, dysmenorrhea, occurrence of pregnancy and recurrence. Second look laparoscopy was performed 3-6 months postoperatively in patients with infertility and pelvic adhesions to assess results of surgical treatment and adhesiolysis procedure.
Results: Subjective improvement of pelvic pain and/or dysmenorrhea occurred in 75.86% of patients. Recurrence of pelvic endometriosis occurred in 12.19%. Four of these cases were stage III or IV disease. In three patients recurrence was limited to ovarian endometriomas. The mean adhesion score at second look laparoscopy in infertile patients (19 cases) was 9.4 (SD±3.6) compared with 15.7 (SD ± 3.1). The difference was statistically significant. Pregnancy occurred in 5 cases (17.8%), 3 of them had no adnexal adhesions at initial laparoscopic surgery.
Conclusion: Preliminary results have shown that ABC is a safe and effective new surgical tool for use in laparoscopic surgery for pelvic endometriosis. Further evaluation is however needed.

ABSTRACT
Objectives: The study was designed to assess the impact of limited proteolysis, using a-chymotrypsin in high viscosity semen specimens, on the qualitative and quantitative characteristics of spermatozoa recovered via the SpermPrep filtration and Percoll gradient centrifugation methods for possible use in assisted reproductive technologies (ART).
Design: Controlled clinical study.
Setting: Andrology Institute of Lexington.
Patients: Thirty patients producing high viscosity semen specimens, which otherwise were within normospermic limits, participated in this study.
Main Outcome Measures: Treatment of high viscosity semen specimens via limited proteolysis using a-chymotrypsin and preparation via the SpermPrepTM filtration or Percoll gradient centrifugation methods.
Results: The method of semen liquefaction as applied in this study aided in the recovery of greater numbers and higher quality spermatozoa (P<0.05) as compared to the conventional method. Improvements in all qualitative measurements assessed were noted between the conventional and the a-chymotrypsin liquefied specimens regardless of the sperm selection method employed.
Conclusions: The limited proteolysis of high viscosity semen specimens with a-chymotrypsin was shown to be a treatment which can assist significantly in the handling and preparation of human seminal specimens with viscosity difficulties. Furthermore, limited proteolysis of high viscosity semen specimens with a-chymotrypsin assisted in the recovery of greater numbers and higher quality spermatozoa which can be used further in the various assisted reproductive techniques.

ABSTRACT
Objective: To prevent the onset of a severe OHSS (ovarian hyperstimulation syndrome) different protocols of luteal phase support depending on the estradiol value and the number of follicles are used in this study. In a high risk group, the patients receive 600 mg per day micronized progesterone intravaginally. If at least one high grade embryo is transferred in this high risk group, the patients additionally receive 5000 IU of hCG on day of embryo transfer. Otherwise the patients received three hCG injections.
Design: Reprospective study of 678 consecutive ICSI (intracytoplasmic sperm injection) cycles.
Setting: Infertility day clinic, Department of Gynecology and Obstetrics.
Patients: Six hundred and seventy eight cycles undergoing infertility treatment.
Main outcome measures: Differences in the pregnancy rate after the three different ways of luteal phase support.
Results: There was no difference between the groups regarding the mean age of the patients, the contribution of the different kinds of sterility, or the number of previous cycles. The implantation and pregnancy rates were low in the progesterone-only group. This may be due to either the protocol of luteal phase support - chosen as a consequence of a threatening OHSS and/or the lower rate of good quality oocytes received.
Conclusion: An injection of hCG on the day of embryo transfer in addition to the administration of progesterone in patients at risk of OHSS may increase the pregnancy rate. To exclude other variables from this analysis and to answer, whether there is really a benefit for these patients, a prospective, randomized study has to be done.

ABSTRACT
Objective: To compare two sperm immobilization-injector pipette loading-injection techniques.
Design: Prospective randomized study.
Setting: Miami IVF/ICSI center, Alexandria, Egypt. It is a private center.
Subjects: 728 oocytes were retrieved from
109 patients stimulated by a long agonist protocol and undergoing intracytoplasmic
sperm injection (ICSI) for severe male factor infertility in the period
from 1/8/96 to 15/11/96.
Interventions: Oocytes were randomly assigned to one of the following
microinjection techniques: 1) Technique A (Single loading technique): The
number of motile sperm required for the injection of the available oocytes
were selected and immobilized. Thirty to fifty minutes after immobilization
all the required immobilized sperm were loaded together in the microinjection
pipette and oocytes were injected one after the other using the loaded
pipette. 2) Technique B (Multiple loading technique): For every oocyte
one motile sperm was selected, immobilized and immediately used for oocyte
microinjection. One sperm is loaded in the injection pipette at a
time.
Main Outcome Measures: Fertilization and
cleavage rates, and percentage of grade I or II embryos.
Results: Technique B compared to technique A showed a significantly
higher fertilization and cleavage rates (62.4% versus 46.6%, and 84.3%
versus 71.8% respectively). The percentage of grade I or II embryos
were comparable in both techniques (71.8% versus 78% respectively).
Conclusion: Immobilization-injection interval and the technique of injector loading seem to be important variables that affect ICSI performance.
Key words: Intracytoplasmic sperm injection, sperm immobilization-injection interval, cytosolic factor.

ABSTRACT
Objective: To study the effect of intravenous albumin combined with low dose human chorionic gonadotrophin and late step-down administration of menotropins on the prevention of ovarian hyperstimulation syndrome.
Materials and Methods: Ninety three high risk patients with an E2 level >20000 pmol/l on the day of hCG day were followed by serial ultrasonographic examinations and complete blood count analysis after embryo transfer until the day of pregnancy test. All the patients received long GnRHa/HMG protocol. Patients were administered 5000 IU HCG for ovulation triggering and 20 grams 100 cc intravenous albumin at the retrieval day. In addition to this, dose of HMG was reduced in the last few days of the ovulation induction if E2 levels tended to reach the cut off point.
Results: The level of estradiol on the day of hCG was 26171.06 ± 4332.04 pmol/l. No patients developed severe OHSS. In 4 patients moderate OHSS occurred, they were hospitalized only for a few days. Two of them were pregnant. A control group of 313 patients were treated during the same period and had a mean E2 level of 10508 ± 2835.6 pmol/l, and two patients developed severe and 7 patients developed moderate ovarian hyperstimulation syndrome. Both of the severe and one of the moderate OHSS patients were pregnant. The overall pregnancy rate of 406 cycles per retrieval dthe same time period was 29.2 % and this rate in the high risk group was 31.18 %.
Conclusion: Intravenous albumin combined with low dose hCG and late step-down administration of menotropins proved to be effective in the prevention of severe ovarian hyperstimulation syndrome.

ABSTRACT
Objective: To study morbid anatomy of the pelvis in women with secondary infertility who had delivered once by cesarean section (CS).
Design: retrospective study.
Setting: Teaching Hospital Ministry of Health, Makkah, Saudi Arabia.
Patients: 40 patients with secondary infertility
, 40 fertile patients with one previous CS and 40 patients with secondary
infertility after vaginal delivery. The three groups were of the same age
and race.
Interventions: Pelvic ultrasound scan, Hysterosalpingography
(HSG), Hysteroscopy and Laparoscopy. Day 3 hormonal profile: follicle stimulating
hormone (FSH), luteinizing hormone (LH), Prolactin, Estradiol, testosterone,
Thyroid stimulating hormone (TSH) and luteal phase progesterone assay.
Main outcome measures: morbid anatomy of cervix, uterus, tubes, ovaries, and pelvic peritoneum.
Results: The uterus was found adherent to the abdominal wall with limited mobility in 20 cases (50%) compared to 5 cases in control group 1. 5 cases had high ovarian position. Short cervix ( less than 2 cm) was present in 5 cases and the anterior lip of the cervix was absent in 3 cases. Cervix to uterus ratio was increased in 3 cases. There were 10 cases of tubal block of whom 7 cases were bilateral .Control group 2 included 6 cases of tubal block of whom 4 were bilateral. Moderate tubo-ovarian adhesions were present in 9 cases compared to 2 cases of mild adhesions in both control group 1 and control group 2. There were 3 cases of hydrosalpinges, and two cases of frozen pelvis in the study group. In addition, there were two cases of severe intrauterine synaechia , one case of endometritis and two cases of vesico-uterine fistula.
Conclusion: This study demonstrates that patients with secondary infertility and a history of previous one cesarean section, may have significant pelvic abnormalities and these women should be screened for such abnormalities prior to their infertility therapy.
