In Vitro Fertilization01:24

In Vitro Fertilization

1.6K
In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...

Infertility in Females

4.8K
Female infertility is defined as the inability to conceive after a year of regular, unprotected intercourse and affects about 10–15% of couples worldwide. The primary cause of female infertility is ovulatory disorders, which hinder the release of eggs. These disorders can be classified as hypothalamic amenorrhea, polycystic ovarian syndrome (PCOS), premature ovarian failure, and hyperprolactinemic anovulation disorders.
Endometriosis, a condition characterized by abnormal growth of...

Fertilization

During fertilization, an egg and sperm cell fuse to create a new diploid structure. In humans, the process occurs once the egg has been released from the ovary, and travels into the fallopian tubes. The process requires several key steps: 1) sperm present in the genital tract must locate the egg; 2) once there, sperm need to release enzymes to help them burrow through the protective zona pellucida of the egg; and 3) the membranes of a single sperm cell and egg must fuse, with the sperm...

Birth Control Methods

5.6K
Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although...

Infertility in Males

665
Male infertility affects millions of couples worldwide, arising from various factors that impact different stages of the reproductive process. An endocrine imbalance resulting from conditions like hypogonadism, Klinefelter syndrome, or pituitary disorders can disrupt hormone levels and reduce sperm production. Testicular defects, such as tumors, cryptorchidism, atrophic testes, abnormal sperm morphology, and low sperm count or motility, may arise due to genetic factors, structural...

Intrauterine Drug Delivery Systems01:21

Intrauterine Drug Delivery Systems

168
Controlled-release systems for intravaginal and intrauterine drug delivery have been developed primarily for the administration of contraceptive steroid hormones. These delivery routes circumvent first-pass hepatic metabolism, thereby enhancing bioavailability and allowing for reduced systemic dosages compared to oral administration. Such approaches contribute to improved therapeutic efficacy and patient compliance, particularly in long-term contraceptive regimens.Intravaginal Drug Delivery...

Summary

Having intercourse during the peri-implantation window may reduce pregnancy chances. Timing intercourse to the fertile window could improve conception rates and decrease time to pregnancy.

Area of Science:

  • Reproductive endocrinology and fertility studies.
  • Human reproductive physiology.
  • Clinical obstetrics and gynecology.

Background:

  • Understanding factors influencing natural conception is crucial for fertility management.
  • The optimal timing of intercourse for conception remains an area of interest.
  • Previous research has focused on the fertile window, but the peri-implantation phase's impact is less understood.

Purpose of the Study:

  • To investigate the association between sexual intercourse during the peri-implantation window and the probability of achieving pregnancy.
  • To determine if intercourse timing around implantation affects natural fertility outcomes.

Main Methods:

  • A time-to-pregnancy cohort study was conducted.
  • Day-specific probability of pregnancy modeling was used to analyze intercourse timing.
  • Data from a community cohort of women aged 30-44 trying to conceive naturally were analyzed.

Main Results:

  • Analysis included 1,332 cycles from 564 women.
  • Intercourse during the peri-implantation window was significantly correlated with intercourse frequency during the fertile window.
  • Cycles with intercourse on 2 or more days during the implantation window showed a significantly lower probability of pregnancy (fecundability ratio, 0.62).

Conclusions:

  • Sexual intercourse during the peri-implantation window may negatively impact natural fertility.
  • Timing intercourse to the fertile window may enhance conception probability and reduce time to pregnancy.
  • This suggests that avoiding intercourse during the peri-implantation phase could be beneficial for couples trying to conceive.
