Treatment of idiopathic oligozoospermia with tamoxifen--a randomized controlled study.

1992

There is no conclusive evidence of the usefulness of tamoxifen in the treatment of idiopathic oligozoospermia (OAT-syndrome), as it has been used mostly in uncontrolled studies. We herein report on the controlled treatment of OAT-syndrome with tamoxifen versus placebo following a randomized design. Seventy-six men with sperm counts of 2-20 x 10(6) ml-1, sperm motility of 20-50%, and sperm morphology (abnormal cells) between 50 and 80% were involved in the study. Patients with varicocele, a history of testicular maldescent or genital inflammation were excluded. Thirty-nine patients received tamoxifen (30 mg daily), 37 patients placebo. There was a statistically significant increase in the me…

Successful gamete intrafallopian transfer following failed artificial insemination by donor: evidence for a defect in gamete transport?

1988

Gamete intrafallopian transfer (GIFT) was offered as an alternative treatment to 48 women who failed to conceive after artificial insemination with donor semen (AID) in numerous attempts (9 to 24 cycles). The evaluation of these women showed no major cause of infertility as evidenced by normal endocrine, cervical, uterine, and tubal factor studies. Their partners were either azoospermic or severely oligoasthenospermic. During the GIFT cycle, follicular development was induced with (1) clomiphene citrate (days 3 to 7) plus human menopausal gonadotropins (hMG) from day 6 on or (2) human follicle-stimulating hormone (days 3 to 4) plus hMG (day 5 on), until ultrasound revealed 2 follicles 16 mm…

Seminal plasma-induced suppression of the respiratory burst of polymorphonuclear leukocytes and monocytes.

1984

Summary: Based on recent findings indicating suppression of lymphocytic functions by seminal plasma (SP) we tested the effects of SP from men with normo- and oligozoospermia (n = 7, each) on the generation of luminol-enhanced chemiluminescence (CL) of polymorphonuclear leukocytes (PMN) and monocytes (Mo) stimulated in vitro with zymosan. We found a complete suppression of CL of PMN and Mo by undiluted SP's, 1,000-fold dilutions still induced ≥ 20 percent inhibition. There was no difference between normo- and oligozoospermic men in inhibition of CL both with PMN and Mo. Protein concentrations of SP's were closely the same; all SP were free of the complement components C4 and C3c. After dialy…
