Comparison of plasma oxytocin level in women with natural and surgical menopause.

Objective: We aimed to investigate plasma oxytocin level in women with natural and surgical menopause and its relation with other metabolic parameters.

Methods: This study included 89 postmenopausal women admitted to menopausal outpatient clinics and gave written consent to participate. Participants were allocated into natural (Group 1; n = 61) and surgical (Group 2; n = 28) menopause groups based on causative process for the onset of menopause.

How do thiol disulfide balance and copper-ceruloplasmin levels change in women using copper intrauterine devices?

We aimed to examine the change in plasma copper (Cu) level and copper transport proteins level before inserting Cu-IUD and after one menstrual cycle and to show the effect of this change on the thiol disulfide balance in women using copper-containing intrauterine device (Cu-IUD).Thirty-three reproductive women who admitted to the gynecology clinic and inserted Cu-IUD were examined in this study. Thiol-disulfide homeostasis, plasma Cu and ceruloplasmin levels and ceruloplasmin ferroxidase activity were measured using the blood samples collected just before inserting Cu-IUD and after one menstrual cycle.

Neopterin and hsCRP are not correlated in gestational diabetes mellitus.

Objective: To determine serum neopterin and high sensitive C-reactive protein (hsCRP) levels in patients with and without gestational diabetes mellitus (GDM).

Methods: Neopterin and hsCRP levels were quantified in 28 women with GDM and 20 pregnant women with normal glucose tolerance (NGT). Postpartum neopterin and hsCRP levels were measured in a follow-up study.

Comparison of copper intrauterine device with levonorgestrel-bearing intrauterine system for post-abortion contraception.

Aim: The aim of this study was to compare the safety, bleeding pattern, effects, side-effects, complications and 6-month continuity rates of levonorgestrel-bearing intrauterine system (LNG-IUS) with conventional copper intrauterine device (Cu-IUD) inserted immediately after voluntary termination of pregnancy up to 10 weeks of gestation.

Methods: One hundred women who underwent voluntary pregnancy termination and preferred IUD insertion as a contraceptive method after counseling were enrolled. The patients were randomly allocated to Cu-IUD or LNG-IUS and followed up at 10 days, and at 1, 3 and 6 months.

Clomiphene citrate 'stair-step' protocol vs. traditional protocol in patients with polycystic ovary syndrome: a randomized controlled trial.

Purpose: To evaluate the efficacy of the stair-step protocol using clomiphene citrate (CC) and to assess the uterine and systemic side effects in patients with polycystic ovary syndrome (PCOS).

Methods: A total of 60 PCOS patients who failed to respond to 50 mg/day for 5 days of CC treatment within the cycle were randomly allocated to the control (traditional protocol) and study (stair-step protocol) groups. In the stair-step protocol,patients were treated with CC 50 mg/day for 5 days and then in nonresponsive patients, the dosage was increased to 100 mg/day for 5 days in the same cycle.
