Venous blood samples were taken daily from 21 regularly menstruating Sudanese women throughout one complete menstrual cycle. FSH, LH, estradiol-17 beta and progesterone were assayed in all plasma samples and normal reference ranges were thus established. Fifteen subjects had a luteal phase of more than 12 days whilst in 3 subjects it was shorter. Two subjects were found to be hyperprolactinemic and one had an anovulatory cycle with an elevated LH. The plasma concentrations of estradiol-17 beta in the follicular phase and progesterone in the luteal phase were significantly lower in subjects with short luteal phase than in those with a luteal phase of more than 12 days. The hormonal profile of FSH, LH, estradiol-17 beta and progesterone throughout a normal menstrual cycle in regularly menstruating Sudanese women was similar to what has been reported in the literature for other ethnic groups.

Effect of overweight and obesity on live birth rate in single euploid frozen embryo transfers.

Research Question: Does endometrial preparation using a natural cycle lead to higher live birth rates (LBR) in single euploid frozen embryo transfers (FET) compared with programmed cycles, for women who are normal weight, overweight and obese.
Design: Retrospective study of 845 single euploid FETs from 688 couples. Patients were stratified by body mass index (BMI) into normal weight, overweight and obesity class I/II categories.

Purpose: To investigate an optimal strategy by assessing the effectiveness of varying follicular sizes on trigger day during luteal phase stimulation protocol and provide evidence for personalized protocol adjustment.
Methods: This was a retrospective study including a total of 661 patients who had started their in vitro fertilization cycle with a luteal phase stimulation (LPS) protocol during 2015-2023. We classified patients into groups according to the size of the dominant proportion of follicles on the human chorionic gonadotropin (hCG) trigger day: large, medium, and small.
Oestrogen and progesterone fluctuate cyclically in women throughout their adult lives. Although these hormones cross the blood-retinal barrier and bind to intraocular receptors, their effects remain unclear. We present the first review to date on associations between posterior pole structures-specifically the macula, choroid, and optic disc-and both the menstrual cycle and post-menopausal period, utilising multimodal imaging techniques in healthy adult non-pregnant women.

An important part of the side effects of combined oral contraceptives (COC) usage is its psychological impact, which includes mood changes, anxiousness and depression. The psychological impacts are expected to be caused by physiological fluctuations of sex hormone levels during the menstrual cycle; this cycling is, however, suppressed in COC users. In our study, we assessed the differences in emotional awareness and anxiousness between women long term users of anti-androgenic COC (AA) and women with no COC use in their medical history (C).

Seed cycling therapy (SCT) involves the consumption of specific seeds during the follicular and luteal phases of the menstrual cycle to help balance reproductive hormones. This study aimed to investigate the effects of SCT on healthy female Wistar albino rats to prevent hormonal imbalances. For SCT, a seed mixture (SM1) consisting of flax, pumpkin, and soybeans (estrogenic seeds) was administered at doses of 5.
