Fertility preservation in >1,000 patients: patient's characteristics, spectrum, efficacy and risks of applied preservation techniques

Data on the characteristics of female patients counselled for fertility preservation and the efficacy and risk of the applied procedures are still poor. We therefore analysed the registry of a network of 70 infertility centers which are involved in fertility preservation in Germany, Switzerland and Austria, called FertiPROTEKT ( hhtp://www.fertiprotekt.eu ).

Clinical recommendation on fertility preservation in borderline ovarian neoplasm: ovarian stimulation and oocyte retrieval after conservative surgery

To evaluate safety and fertility outcome after assisted conception in patients who were treated conservatively for a borderline ovarian tumor (BOT).

Bluetongue disease: impact of the 2008 vaccination on fertility in supervised dairy herds

In June 2008 the compulsary nationwide vaccination against BTV-8 (Bluetongue virus serotype 8) was started. After a short time, several owners complained about undesirable effects of the vaccination on fertility and milk quality. Data from 47 dairy farms, regularly supervised by herd health practitioners, were analysed in order to clarify a possible connection between vaccination and fertility. Both vaccinations given each cow for basic immunization were evaluated according to their effects on conception rate and pregnancy. In model calculations the first vaccination had no significant effect on the first service conception rate (FCR), the all service conception rate (ACR) and on the abortion rate. The second vaccination led to a significantly reduced FCR when the cow was inseminated within 20 days of being vaccinated and to a significantly worse ACR when inseminated 10 days before or after vaccination. However, these individually established reductions of the insemination rate had only little influence on overall data.

Gonadal function and fertility in survivors after Hodgkin lymphoma treatment within the German Hodgkin Study Group HD13 to HD15 trials

To optimize fertility advice in patients with Hodgkin lymphoma (HL) before therapy and during survivorship, information on the impact of chemotherapy is needed. Therefore, we analyzed gonadal functions in survivors of HL.

Fertility preservation in women with malignant tumors and gonadotoxic treatments

Because of improved survival rates and recent advances in reproductive medicine, fertility preservation methods in women of reproductive age with malignant or autoimmune diseases have risen in importance.

Fertility preservation in women with vasculitis: experiences from the FertiPROTEKT network

Fertility preservation is not only important for malignant diseases but should also be offered to patients with autoimmune diseases (AID) like vasculitides, prior to cyclophosphamide therapy. No recommendations are available for patients with AID.

Fertility preservation methods in young women with systemic lupus erythematosus prior to cytotoxic therapy: experiences from the FertiPROTEKT network

Despite new treatment options, some patients with systemic lupus erythematosus (SLE) need to be treated with the cytotoxic agent cyclophosphamide (CYC). Unlike malignant disease, there are no recommendations for ovarian protection in SLE. The clinical experience of the FertiPROTEKT network as well as recommendations after literature review will be presented in this paper.

Fertility and gonadal function in female survivors after treatment of early unfavorable Hodgkin lymphoma (HL) within the German Hodgkin Study Group HD14 trial

In the HD14 trial, 2×BEACOPPescalated+2×ABVD (2+2) has improved the primary outcome. Compared with 4×ABVD, this benefit might be compromised by more infertility in women. Therefore, we analyzed gonadal function and fertility.

[Modalities of acupuncture treatments in assisted reproductive technology--a comparison of treatment practice in Swiss, German, and Austrian fertility centers with findings from randomized controlled trials]

One in 5 couples is affected by infertility. To increase the effectiveness of assisted reproductive technology (ART) adjuvant acupuncture treatments are frequently administered. However, little is known about acupuncture treatment modalities employed in fertility centers. The aim of our study was to assess modalities of acupuncture treatments in fertility centers and compare them with investigated acupuncture treatments in randomized controlled trials (RCTs) related to ART.

Effects of a single administration of prostaglandin F2alpha, or a combination of prostaglandin F2alpha and prostaglandin E2, or placebo on fertility variables in dairy cows 3-5 weeks post partum, a randomized, double-blind clinical trial

BACKGROUND: Delayed uterine involution has negative effects on the fertility of cows; use of prostaglandin F2alpha alone as a single treatment has not been shown to consistently improve fertility. Combined administration of PGF2alpha and PGE2 increased uterine pressure in healthy cows. We hypothesized, that the combination of both prostaglandins would accelerate uterine involution and have, therefore, a positive effect on fertility variables. In commercial dairy farming, the benefit of a single post partum combined prostaglandin treatment should be demonstrated. METHODS: 383 cows from commercial dairy farms were included in this study. Uterine size and secretion were evaluated at treatment 21-35 days post partum and 14 days later. Cows were randomly allocated to one of three treatment groups: PGF2alpha and PGE2, PGF2alpha or placebo. For every animal participating in the study, the following reproduction variables were recorded: Interval from calving to first insemination, days open, number of artificial inseminations (AI) to conception; subsequent treatment of uterus, subsequent treatment of ovaries. Plasma progesterone level at time of treatment was used as a covariable. For continuous measurements, analysis of variance was performed. Fisher's exact test for categorical non-ordered data and exact Kruskal-Wallis test for ordered data were used; pairwise group comparisons with Bonferroni adjustment of significance level were performed. RESULTS: There was no significant difference among treatment groups in uterine size. Furthermore, there was no significant difference among treatments concerning days open, number of AI, and subsequent treatment of uterus and ovaries. Days from calving to first insemination tended to be shorter for cows with low progesterone level given PGF2alpha and PGE2 in combination than for the placebo-group (P = 0.024). CONCLUSION: The results of this study indicate that the administration of PGF2alpha or a combination of PGF2alpha and PGE2 21 to 35 days post partum had no beneficial effect upon measured fertility variables. The exception was a tendency for a shorter interval from calving to first insemination after administration of the combination of PGF2alpha and PGE2, as compared to the placebo group. Further research should be done in herds with reduced fertility and/or an increased incidence of postpartum vaginal discharge.

[Antirheumatic therapy and reproduction. The influence on fertility, pregnancy and breast feeding]

Antirheumatic drugs can have a negative effect on reproduction in both men and women. Possible negative effects are impairment of fertility, harmful effects on the fetus and adverse effects on the breastfed child. In women non-steroidal antiinflammatory drugs (NSAID) and cyclophosphamide can impair fertility. In men infertility can result from the use of salazopyrine and cyclophosphamide. A desire for children should be taken into account before the start of disease modifying drugs (DMARD). Treatment with NSAID is possible at some stages of pregnancy as well as during lactation. A limited number of DMARD is compatible with pregnancy and is presented. Cytostatic drugs and leflunomide must be prophylactically withdrawn before a planned pregnancy. TNF alpha antagonists should be discontinued at the start of pregnancy. Safe birth control must be practised during therapy with drugs that are gonadotoxic or teratogenic. Treatment with immunosuppressive drugs during lactation is limited because of insufficient documentation of safety for the breastfed child.
