Congenital anomalies of the müllerian system

Congenital anomalies of the müllerian system, the most common of which are uterine malformations, are associated with fertility problems. Multifactorial polygenic and familial factors are involved in their formation. The result may be deficient development (agenesis, rudimentary horn, unicornuate uterus), nonfusion (didelphys or bicornuate uterus), or defective canalization of the müllerian ducts (septate uterus). The principal diagnostic procedures include HSG, laparoscopy, hysteroscopy, and US. The clinical presentation varies from symptoms of obstruction of the menstrual flow in adolescence to hypomenorrhea and fertility problems in adult life. Repeated fetal loss, after excluding other reasons, is usually the indication for surgical intervention. Uterine septa should be resected hysteroscopically. A prophylactic cerclage has been suggested by various authors, including those of this work, in cases of symmetric uterine anomalies, especially bicornuate uteri, as a simple and effective treatment to be tried before embarking on major surgery such as metroplasty.

Delayed fertilization and poor embryonic development associated with impaired semen quality

Delayed fertilization is common in cycles with immature oocytes. This phenomenon was observed in 42 of 423 with mature oocytes. Of the 42 cycles, 16 were excluded because of the presence of sperm autoantibodies. Sperm parameters of the remaining 26 (6.1%) cycles (group A) were compared with those in cycles with no fertilization at all (group B) and those in the control group (group C). The percentage of normal forms was 15% in group B and 24% in group A compared with 51% in group C. Fertilization rates were 32% in group A compared with 81% in group C. The incidence of poor embryonic morphology was 82% in group A compared with 29% in group C. Delayed fertilization and poor embryonic morphology associated with impaired sperm quality is of clinical and prognostic importance.

Male genital mycoplasmas and Chlamydia trachomatis culture: its relationship with accessory gland function, sperm quality, and autoimmunity

To study the effect of mycoplasmas and Chlamydia trachomatis infection on semen quality, these microorganisms were cultured from the semen and anterior urethra respectively, in a group of 175 infertile men suspected of a silent genital infection with a poor postcoital test. Chlamydia infection, but not mycoplasmas, was parodoxically more frequent in the apparently normal than oligotetratoasthenozoospermia patients. Mycoplasmas male infection, but not chlamydia, was more frequent in cases with female, mechanical, and/or organic infertility factors. Infection was unrelated to the accessory gland evaluation or sperm variables. However, seminal antisperm antibody activity was significantly increased in cases with any positive culture. By this local antibody increase, chlamydia and mycoplasmas may significantly reduce sperm egg penetration ability.

Investigation of the uterine cavity in recurrent aborters

To prospectively compare the diagnostic ability of both HSG and diagnostic hysteroscopy in recurrent aborters, an HSG followed by a diagnostic hysteroscopy was performed in 106 patients during an investigation into recurrent abortions. The uterine cavity findings on HSG and at hysteroscopy were compared. Among the 60 abnormal HSG patients, intrauterine pathology was demonstrated in 37 (34.9%). Among the 46 normal HSG patients, a normal uterine cavity was found in 33 (31.3%). The sensitivity of the HSG in revealing intrauterine abnormalities was therefore 79% and its specificity 60%. In 23 pathologic HSG, no abnormalities were seen by hysteroscopy. In 13 cases, hysteroscopy demonstrated mild intrauterine findings overlooked by HSG. The false-positive rate was 38% and the false-negative rate was 28%. Hysterosalpingography showed a high false-positive rate, especially in the intrauterine adhesions group. In view of the low specificity and high false-positive and false-negative rates, we believe that hysteroscopic evaluation of the uterine cavity is superior to HSG in recurrent abortions.

Ovarian pregnancy: A report of twenty cases in one institution

A series of 20 cases of primary ovarian pregnancy that were diagnosed and treated in one institution is reported. The prevalence rate of 1:3600 deliveries seems to be increasing in past years and comprises 3.3% of all extrauterine pregnancies. Clinical presentation, possible pathogenesis, diagnostic steps, preferred management, and future fertility are detailed. Inasmuch as all our 18 fertile patients used an intrauterine contraceptive device before the operation, special emphasis is made on the controversial relationship between use of intrauterine contraceptive devices and ovarian pregnancy.

Hysteroscopy is superior to hysterosalpingography in infertility investigation

Background. The development of advanced endoscopic instrumentation in recent years has demonstrated the superiority of direct visual examination over radiographic demonstration of various body cavities. Just as laparoscopy has gradually taken a primary role in the surgical investigation of the ovulatory infertile patient, the role of intrauterine endoscopy in comparison to hysterosalpingography (HSG) needs to be reevaluated.

Mifepristone (RU486) alone or in combination with a prostaglandin analogue for termination of early pregnancy: a review

The availability of a medical mode of termination of early pregnancy by the administration of RU486, an antiprogesterone alone, or in combination with one of the PG analogues significantly reduces the maternal morbidity and mortality associated with the classical surgical abortion. RU486 given alone in early pregnancy induces complete abortion in 60% to 85% of cases, and when combined with prostaglandin analogues, gemeprost or sulprostone, reaches a success rate of 95% to 99%. RU486 may also be of potential value in the medical treatment of ectopic pregnancy. Its use as a postcoital contraception is suggested, but further research is required to determine whether RU486 can be used on a once-a-month basis for contraception.

Pregnancy rate and ovarian hyperstimulation after luteal human chorionic gonadotropin in in vitro fertilization stimulated with gonadotropin-releasing hormone analog and menotropins.

The value of luteal phase supplementation with human chorionic gonadotropin (hCG) was assessed after a combined protocol of ovarian stimulation, using a long acting gonadotropin releasing hormone analog (GnRH-a) and human menopausal gonadotropins (hMG), in a randomized prospective study of 36 consecutive cycles in an in vitro fertilization (IVF) program. The patients were allocated on the transfer day to either luteal phase supplementation with hCG (Group A, n = 18) or none (Group B, n = 18). Nine patients of Group A conceived as compared with 3 in Group B. Five patients, all in Group A, developed ovarian hyperstimulation syndrome (OHSS) (3 moderate and 2 severe forms). Analysis of the hormonal profiles disclosed similar progesterone (P), estradiol (E2), and E2/P ratio up to the 6th post ovum pick-up day. Then, E2 and mainly P levels decreased only in Group B resulting in a rising E2/P ratio. These findings stress the importance of luteal support in IVF cycles treated with GnRH-a. In light of the increased risk of OHSS among hCG treated patients, further studies are needed to assess the optimal preparation needed.

Conservative management of adnexal torsion in premenarchal girls

STUDY OBJECTIVE To evaluate treatment of premenarchal girls with torsion of the adnexa. DESIGN Retrospective review of medical records (Canadian Task Force classification II-2). SETTING Tertiary care, university-affiliated hospital. PATIENTS Eight premenarchal girls (age range 3-12 yrs) with twisted adnexa. INTERVENTION Laparoscopic detorsion and follow-up with B scan and Doppler ultrasound imaging. MEASUREMENTS AND MAIN RESULTS Duration of complaints ranged from 8 to 72 hours (mean 34.6 hrs) and the interval from admission to surgery ranged from 6 to 24 hours (mean 18.7 hrs). Four patients had torsion of normal-appearing adnexa. The other four had ovarian neoplasms. Two had cystic mature teratomas (dermoid cysts) and one a serous cystadenoma that required additional operation. The fourth girl had a simple ovarian cyst that was aspirated laparoscopically. Seven girls (87%) had normal-appearing ovaries on follow-up ultrasound. In one patient, a small ovary was seen, with no intraovarian blood flow on color Doppler. CONCLUSION Although the diagnosis of torsion of the adnexa in premenarchal girls is difficult and usually delayed, laparoscopic detorsion seems to be an effective adnexa-sparing approach. We suggest that laparoscopy should be the treatment of choice and that detorsion, rather than adnexectomy, be performed more often in these patients.

Role of Sonography in the Diagnosis of Retained Products of Conception

Objective. To present our experience with clinical and sonographic diagnosis of retained products of conception and to evaluate its correlation with histopathologic findings. Methods. This was a retrospective study on 156 patients admitted for retained products of conception. Women were referred because of 1 or more of the following: abdominal pain, bleeding, and fever. The status of the cervix was evaluated by bimanual examination. The diagnosis of retained products of conception was made when a sonographic finding of hyperechoic or hypoechoic material was seen in any part of the uterine cavity or the presence of a thickened endometrial stripe greater than 8 mm and an irregular interface between the endometrium and myometrium was found. One hundred twenty‐one women (77.6%) were admitted after dilation and curettage for abortion, and 35 (22.4%) were admitted after spontaneous labor. Results. Histopathologic reports confirmed the diagnosis of retained products of conception in 86 (71%) of 121 women in the postabortion group and in 17 (48.5%) of 35 women in the postpartum group. The overall false‐positive rate for sonographic diagnosis was 34%. For women after abortion and after delivery, the false‐positive rates were 28.9% and 51.5%, respectively. Conclusions. Reliance on common signs and symptoms to diagnose retained products of conception as well as the use of sonography is associated with an unacceptably high false‐positive rate, mainly after delivery. A more conservative approach to the treatment of retained products of conception is suggested.
