TL;DR: Semen quality of the reference population was superior to that of the men from the general population and normozoospermic men, and provide an appropriate tool in conjunction with clinical data to evaluate a patient's semen quality and prospects for fertility.
Abstract: BACKGROUND Semen quality is taken as a surrogate measure of male fecundity in clinical andrology, male fertility, reproductive toxicology, epidemiology and pregnancy risk assessments. Reference intervals for values of semen parameters from a fertile population could provide data from which prognosis of fertility or diagnosis of infertility can be extrapolated. METHODS Semen samples from over 4500 men in 14 countries on four continents were obtained from retrospective and prospective analyses on fertile men, men of unknown fertility status and men selected as normozoospermic. Men whose partners had a time-to-pregnancy (TTP) of < or =12 months were chosen as individuals to provide reference distributions for semen parameters. Distributions were also generated for a population assumed to represent the general population. RESULTS The following one-sided lower reference limits, the fifth centiles (with 95th percent confidence intervals), were generated from men whose partners had TTP < or = 12 months: semen volume, 1.5 ml (1.4-1.7); total sperm number, 39 million per ejaculate (33-46); sperm concentration, 15 million per ml (12-16); vitality, 58% live (55-63); progressive motility, 32% (31-34); total (progressive + non-progressive) motility, 40% (38-42); morphologically normal forms, 4.0% (3.0-4.0). Semen quality of the reference population was superior to that of the men from the general population and normozoospermic men. CONCLUSIONS The data represent sound reference distributions of semen characteristics of fertile men in a number of countries. They provide an appropriate tool in conjunction with clinical data to evaluate a patient's semen quality and prospects for fertility.

TL;DR: Fertility preservation is often possible in people undergoing treatment for cancer and should be considered as early as possible during treatment planning, to preserve the full range of options.
Abstract: Purpose To develop guidance to practicing oncologists about available fertility preservation methods and related issues in people treated for cancer. Methods An expert panel and a writing committee were formed. The questions to be addressed by the guideline were determined, and a systematic review of the literature from 1987 to 2005 was performed, and included a search of online databases and consultation with content experts. Results The literature review found many cohort studies, case series, and case reports, but relatively few randomized or definitive trials examining the success and impact of fertility preservation methods in people with cancer. Fertility preservation methods are used infrequently in people with cancer. Recommendations As part of education and informed consent before cancer therapy, oncologists should address the possibility of infertility with patients treated during their reproductive years and be prepared to discuss possible fertility preservation options or refer appropriate and interested patients to reproductive specialists. Clinician judgment should be employed in the timing of raising this issue, but discussion at the earliest possible opportunity is encouraged. Sperm and embryo cryopreservation are considered standard practice and are widely available; other available fertility preservation methods should be considered investigational and be performed in centers with the necessary expertise.

TL;DR: In this paper, the main states of India are broadly grouped into two demographic regimes, i.e., northern kinship/low female autonomy and southern kinship /high female autonomy, and the analysis suggests that family social status is probably the most important element in comprehending Indias demographic situation.
Abstract: The main states of India are broadly grouped into 2 demographic regimes. In contrast to states in the north southern states are characterized by lower marital fertility later age at marriage lower infant and child mortality and comparatively low ratios of female to male infant and child mortality. The division between the 2 regimes broadly coincides with the division areas of northern kinship/low female autonomy and southern kinship/high female autonomy. The analysis suggests that family social status is probably the most important element in comprehending Indias demographic situation. Women in the south tend to be more active in the labor force are more likely to take innovative action in adopting fertility control and are more apt to utilize health services for themselves and their children. Changes in India are also compared to those other South Asian countries. (authors modified) (summaries in ENG FRE SPA)

TL;DR: No studies have yet demonstrated that women on oral pills are at increased risk for growth of these tumors, and low-dose contraceptives should not be contraindicated in patients with leiomyomata if they desire to use this form of contraceptive.
Abstract: PIP: 1 out of 4-5 women develop uterine leiomyomata, the most common solid pelvic tumors in women. This paper assesses the reports of 4714 myomectomies and records of 59 personal cases. Townsend et al. suggested that leiomyomata are unicellular in origin. Estrogen, growth hormone, and progesterone may influence the growth of the tumors. In the performance of myomectomy, the 2 major technical concerns are the minimization of blood loss and the prevention of postoperative adhesions. Although most leiomyomata are asymptomatic and grow slowly, 20-50% of the tumors are estimated to produce symptoms, the severity of which depends upon the number, size, and location of the tumors. The symptoms include menorrhagia, infertility, fetal wastage, pelvic pain/pressure, polycythemia, ascites, impingement, and related complications (e.g., ulceration and infection, fever, pain, uterine inversion, sarcomatous change). Asymptomatic patients with uteri of less than 10-12 weeks' gestational size require no more than observation at 6-month intervals regardless of fertility status. For women with uteri of 10-12 weeks gestational size or longer, management will depend on the patient's desire for fertility. Women desirous of fertility should have a 6-12 month trial for conception. If tumor growth is rapid, myometomy may be performed earlier. Women not desirous of fertility (e.g., pre- and post-menopausal) should have total abdominal hysterectomy and bilateral salpingo-oophorectomy. For symptomatic patients desirous of fertility, myomectomy using the transabdominal approach or hysteroscopy should be performed. For symptomatic patients not desiring fertility, dilatation and curettage and hysterectomy should be performed. With regard to oral contraceptive use, no studies have yet demonstrated that women on oral pills are at increased risk for growth of these tumors. Low-dose contraceptives should not be contraindicated in patients with leiomyomata if they desire to use this form of contraceptive. With IUD users, the device should be discontinued if bleeding occurs.
